Know What You Want
Know What You Want From Sonoma County Auto Oil Change Centers

Before you start looking for an auto oil change shop in Sonoma County, it’s important to know precisely what you want. If you’re unsatisfied with your current auto oil change facility and need a new  mechanic for routine automobile maintenance, ask yourself what you are unhappy with.

Is it the manner of service you’ve received? Is it the quality of the service? Knowing exactly what you’re dissatisfied with in your previous Sonoma County auto shop experience will help you find a new auto oil change shop with the things you’re looking for. You will have a better idea of the right questions to ask to avoid problems and ensure high quality auto oil changes.

You may need your car to be maintained or repaired immediately and quickly. You will want to be precise in describing the problems you’re having and your expectations for the auto oil change shop, which will help you to evaluate the response you receive from the individual auto oil change shop and its fit for your automotive needs. Be able to answer to these questions:

  • Do I want a Diamond Certified company that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  • How often will I need to return for oil change, oil filter, or other automotive lube services?
  • What is the owners’ manual recommendation for engine oil change intervals and other automotive fluid requirements?
  • What grade and weight and brand of motor oil do I need?
  • What is the motor oil capacity of my vehicle, and does that amount exceed the engine oil amount provided for the standard shop fee?
  • Is my engine oil level decreasing too rapidly, and what does that mean?
  • Are there particular engine performance problems I am hoping to resolve by the motor oil change, and is an oil change likely to resolve these?
  • Does the cost of the oil change include other complimentary services?
  • How long will the typical range of services take?
  • Do I also want brake fluid, power steering fluid, windshield wiper fluid and automotive coolant fluid to be checked and replenished, and do I need transmission fluid changes, differential fluid, automotive refrigerant, and engine oil additives?
  • Do I want the additional value (and expense) of such maintenance services as tire-pressure checks and tire rotations, overall engine inspection, hose, belt, exterior light and battery connection inspections, and smog checks?
  • Do I want to combine oil change and other preventive services with other types of auto maintenance and repair, such as brake pad replacement, tire replacements, fuel filter changes, or air filter replacements?
  • Am I hearing unusual noises, or feeling vibration or pulling that I also need to have addressed?
  • Are the oil change technicians properly trained and certified, and is there API certification for the products used in the process?
  • Does the auto maintenance shop offer any particular credentials or evidence of good reputation in the community?

What To Ask In Person
What to Ask Sonoma County Auto Oil Change Mechanics in Person

Once you’ve addressed your itemized questions for an auto oil change shop, you should personally visit some local shops in Santa Rosa, Healdsburg, Windsor, Rohnert Park, and Petaluma and other areas of Sonoma County.

Questions you may want to ask there include:

  • How long will it take your auto oil change center to do the auto maintenance and repair work?
  • What information will you need to contact me on my auto oil change or other auto maintenance work?
  • What brands of motor oil and engine oil filters do you use?
  • Will your motor oil service shop honor any warranties on my vehicle?
  • Will the oil change maintenance affect my manufacturer’s warranty?
  • Do you provide a written, itemized estimate for all the auto maintenance work to be undertaken?
  • How do you price auto oil change services? (Flat fee pricing or otherwise?)

  • What To Ask References
    Questions for Previous Auto Oil Change Customers in Sonoma County

    How can you know that auto oil change facilities in Sonoma County have a record of providing high-quality auto oil change services?

    That’s where research and independent surveys come in. All Diamond Certified auto oil change shops have undergone a ratings process that most other companies can’t pass. If you want quality from an auto maintenance shop in Sonoma County and the greater Bay Area, you’ll have confidence when choosing Diamond Certified companies.

    You can read Diamond Certified reports on all certified companies, including verbatim survey responses. And you’ll never be fooled by fake reviews because all research is performed by live telephone interviews of a large, random sample of real customers.

    If you can’t find a Diamond Certified auto maintenance shop within reach, you’ll need to conduct some research of your own. Even if you’re in a hurry to get your maintenance done right away, it is still a good idea to take a little time to check references. If you do, auto oil change shops in Sonoma County should be willing to give you a list of recent engine oil change customers you can call.

    Keep in mind, though, that references provided by the shops are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references are “cherry-picked,” not randomly selected from all customers, so shops are likely just giving you a few satisfied customers to call.

    If you do call on auto maintenance references, specifically ask for a list of their most recent customers (to help avoid them giving you only customers they know were satisfied) and call those references. Ask general questions about their experience with the shop’s personnel as well as specific questions about the car maintenance.

    Questions you might want to ask include:

    • What auto oil change, lube, or maintenance services did _(auto oil change shop name_) do for you?
    • Were you satisfied with the car maintenance at this Sonoma County auto oil change shop?
    • Were you satisfied with the auto oil change technicians’ turn-around time?
    • Did the auto oil change mechanics and service writers listen to you courteously and communicate with you promptly?
    • Do you feel the final price was fair for the auto oil changes you had done?
    • What did you most like about this particular Sonoma County automotive maintenance shop?
    • Would you go back for auto maintenance?
    • Would you recommend or have you recommended this auto oil change garage?

  • Review Your Options
    Making Your Final Decision on an Oil Change Location in Sonoma County

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Finally, review the notes you took during phone and in-person interviews with the auto oil change and auto maintenance shops and determine if one stands out from the rest.

    Pay attention to the following:

    • Can an auto oil change shop in Sonoma County satisfy your requirements for scheduling, auto oil changes, part preferences (OEM parts or aftermarket auto parts), and meet your expectations for courteous and timely service?
    • Does the representative communicate clearly and effectively?
    • Is the auto oil change shop committed to quickly and safely getting your car back on the road?
    • Have I carefully identified my auto oil change and auto maintenance needs,
    • Do I have reason to believe from my search that the shop I have selected is an excellent fit for those needs?

  • How To Work With
    Before you Hire an Oil Change Expert

    Although all auto oil change shops in California must be licensed by the Bureau of Automotive Repair, it does not follow that any particular one will provide the best match for your car maintenance needs.

    Bear in mind your specific goals and expectations for auto oil change services, and remember that all Diamond Certified companies have already been thoroughly vetted on your behalf. If you’re unable to choose a Diamond Certified auto maintenance or auto oil change shop in your area of Sonoma County, you should find the best company based on your own search.

    Auto oil change mechanics in Sonoma County, including those in the larger cities of Healdsburg, Santa Rosa, Rohnert Park, Windsor and Petaluma, may have more experience in particular areas of auto maintenance, and may have special certifications.

    Accurate Auto Oil Change Estimates at Sonoma County Oil Change Services
    Be as detailed as possible, and don’t let yourself be rushed. It’s important to answer the representative’s questions and listen to his or her suggestions and observations. If you don’t understand something, ask for an explanation. You should fully understand the auto maintenance services to be provided.

    The preventive maintenance estimate must be provided to you in writing before the work begins. This estimate must include the total estimated cost for all parts and labor.

    If the estimated auto maintenance or auto oil change costs are more than the original estimate, the shop must contact you before they move ahead with the maintenance.

    Sign a Contract with Your Auto Oil Change Shop for Auto Oil Change Work
    When you’re satisfied with the information your Sonoma County shop has given you, sign the estimate and service agreement. Verify that the auto oil change facility has a phone number where the representative can reach you at all times while your vehicle is in the shop.

    He or she must get your approval for any additional work, and it can slow down or even stop progress on your maintenance if he or she can’t reach you to get consent for work not listed on the original work order.

  • Be a Good Customer
    How Can You Be a Good Auto Oil Change Shop Customer?

    It’s the auto oil change shop’s responsibility to perform a thorough and complete oil change on your car. But you play a big part in the success of your automobile’s lube and maintenance. Here are a few simple steps you can take when you take your minivan, truck or car into an auto oil change shop.

    • Be clear and upfront with the auto oil change representative. Let him or her know what the problem is, what outcome you’re expecting from the vehicle maintenance and specific ways he or she can satisfy your expectations.
    • Ask your service writer to call you with updates, or whether you should call to check on the progress of your vehicle maintenance.
    • Be sure your service writer has a phone number where he or she can reach you at all times while your car or truck is in for car maintenance in Sonoma County, including the larger cities of Sebastopol, Cloverdale and Sonoma.

Top 10 Requests
Oil Change Locations in Sonoma County Offer These Services and More

Automotive maintenance and repair shops in Sonoma County provide all types of automobile maintenance services. The following are the most familiar requests for local auto oil change shops.

Engine Oil Change Service
Engine oil, or motor oil, provides a layer of hydrocarbon fluid between engine parts to reduce friction. Friction creates heat, decreases power, increases fuel usage, and wears down engine surfaces: leading to disrepair and failure in internal combustion engines and transmissions. During regular vehicle use, motor oil deteriorates and loses valuable lubrication properties, and therefore needs to be replaced regularly, probably at least every 7,500 miles.

Engine Oil Filter Change Service
Engine oil filters capture contaminants from engine oil. During routine engine operation over time, motor oil breaks down and forms a sludge of combustion products and metal particles, and engine oil filters become clogged. Regular oil filter changes are therefore necessary.

Motor Oil Replacement Services in Sonoma County
Motor oil is made up largely of additives. Although motor oil itself perhaps does not deteriorate, the additives which make up some one third of its volume, do degrade over time. In addition some motor oil loss inevitably occurs during typical operation, from leakage, and this motor oil must be replaced.

Lube and Oil Change Service
Lube is the short version of the term “lubrication.” Lubrication refers to decreasing friction between moving engine and transmission parts, and thus lube services are generally synonymous with engine oil changes and transmission fluid or transmission oil changes. These services will also sometimes include the replacement of engine oil filters and transmission oil filters. Chassis lubrication is another service sometimes performed in a routine lube service package.

Auto Fluid Maintenance
Fluid levels are very important in automotive maintenance. Engine oil is hardly the only consideration, and the point of motor oil and oil filter change is a convenient time to consider auto filter maintenance. Transmission fluid, brake fluid, power steering fluid, and automotive coolant levels are all very significant for reliable vehicle operation. Even windshield wiper fluid can be crucial, as anyone who has run out can easily confirm. Remember as well that it is always a good idea to have a quart or two of motor oil in your car for emergencies that may develop.

Auto Filter Maintenance
The engine oil filter is perhaps the most crucial for vehicle operation, but several others are important as well. These include the transmission filter, the fuel filter, the cabin air filter, and the engine air filter. Getting oil change services may be a convenient reminder for having auto filter maintenance done as well.

Tire Pressure Checks and Tire Rotation
Tire care is a necessary element of automobile maintenance due to the effect of constant road friction and road hazards. Tire rotation can help maximize effective tire life, and tire pressure checks help maintain optimum tire pressures for safety, longevity, and fuel efficiency.

Synthetic oil
Synthetic oil is now widely used for engine lubrication. Synthetic oil offers premium lubrication properties, and may be particularly important in extreme weather conditions.

Glossary Of Terms
Glossary of Terms Associated with Oil Change Facilities

Below are key auto oil change and auto maintenance terms that are frequently used by local oil change and lube centers.

air filter
A paper or synthetic filter that prevents dust, dirt and debris from entering the engine.

Also known as: auto air filters, car air filter, performance air filter, auto air filter replacements, auto cabin air filter

aftermarket oil change parts
Auto oil change parts not made by the original manufacturer. Aftermarket parts are made by a secondary company to fit and function like the original parts, but are generally less expensive because they are not made by the car manufacturer.

auto oil change shop
An automotive shop that specializes in auto oil changes and may offer other services to maintain automobiles.

Also known as: auto oil change garage, car maintenance shop, auto maintenance shop, automotive maintenance facility

auto engine oil service
Provision of engine lubrication and filter replacement. Fresh engine oil reduces wear and power loss in internal combustion engines by providing a layer of lubrication between engine parts, and clean engine oil filters improve the removal of contaminants.

Also known as: motor oil service, lube and oil change service, oil filter change, change oil filter

auto transmission oil service
Provision of transmission lubrication and filter replacement. Fresh transmission oil reduces wear and power loss by providing a layer of lubrication between transmission parts, and clean transmission oil filters improve the removal of contaminants.

Also known as: transmission lube and oil change service, transmission fluid change, transmission oil filter change

engine oil
The substance that lubricates and cools engine parts. Oil eventually becomes contaminated by moisture, soot and fuel, and moisture causes build-up. Additives in engine oil account for nearly a third of engine oil volume, and their deterioration is a key reason for frequent engine oil changes.

Also known as: motor oil, engine lubrication, auto lubrication

engine oil additives
Additional substances in motor oil. About a third of motor oil volume is engine oil additives which fight contamination and suffer wear between oil changes.

Also known as: motor oil additives, engine lubrication additives, auto lubrication additives

engine oil filter
The device that strains and removes dirt from the engine oil to improve engine lubrication. Oil filters eventually become full of contaminants such as particles and sludge, and need to be replaced.

Also known as: motor oil filter

engine oil consumption
A fact of automobile engines; engine oil gets past rings and seals and is burned in the fuel chamber. Although some motor oil consumption is normal, a given amount may also be too great. Engine use of no more than a quart of oil in 3000 miles indicates good condition, and use of no more than a quart in 1500 miles is also fairly good. Blue exhaust and excessive use of engine oil may indicate the need for engine repair.

Also known as: motor oil use, motor oil consumption, engine oil burning, engine oil loss

engine oil gauge
The dashboard indicator of oil pressure. A warning light means a low oil level requiring immediate refill, and is a serious automotive emergency.

Also known as: engine oil pressure gauge, engine oil warning

engine oil pan
The pan at the bottom of the automobile crankcase. In the engine oil change process, used motor oil is drained away by removal of the oil drain plug at the bottom of the engine oil pan.

Also known as: engine oil plug

foreign auto oil change shops
Foreign auto oil change shops may be available to perform maintenance on vehicles manufactured by foreign car companies, including some models built in the United States.

synthetic engine oil
Synthetic oils provide engine oil fluidity in sub-freezing conditions. They also have lubrication advantages at high temperatures.

Also known as: synthetic lubricants

Frequently Asked Questions
FAQs for Local Oil Change Services

Q: Why choose a Diamond Certified auto oil change shop?
A: Diamond Certified ends the guessing game by offering a list of top rated local companies that have passed the country’s most in-depth rating process. Most companies can’t pass, so only local auto oil change shops rated Highest in Quality and Helpful Expertise® earn the Diamond Certified award.

And your purchase is backed by the Diamond Certified Performance Guarantee, so you’ll feel confident choosing a Diamond Certified auto oil change shop for your vehicle maintenance.

Q: What rights do I have as a consumer in Marin County when it comes to automotive maintenance?
A: You have the right, under the Automotive Repair Act of 1974,  to a written estimate for all car maintenance or repair work, and the right to detailed invoices that list all work done and parts supplied. Visit the Bureau of Auto Repair’s website for more information.

Q: What is an oil change?
A: An engine oil change is a crucial element of automobile maintenance, and specifically of preventive auto maintenance, perhaps the most important aspect of automotive service.  An oil change replaces degraded engine oil with freshly manufactured high quality motor oil for superior lubrication of moving engine parts.

Q: What is an oil filter change?
A: An engine oil filter change is a crucial complement to an engine oil change in preventive automobile maintenance. An oil change replaces the deteriorated engine oil; an oil filter change replaces the filter impaired by a collection of sludge and engine particles with a new clean one, for maintaining the optimal engine lubrication provided by the fresh engine oil.

Q: Why is an engine oil change and engine oil filter change important?
A: Automobile engines are subject to wear, power loss, and eventual failure because of friction between the moving parts of motors.  Motor oil decreases engine friction, thus increasing power and gas mileage and prolonging automobile engine life.  Oil filters keep the engine oil relatively free from products of combustion and engine surface breakdown.  Over time, engine oil deteriorates, and engine oil filters are filled up with contaminants, so the motor oil and the engine oil filter need to be replaced.

Q: What engine oil SAE viscosity grade should I use?
A: Your manufacturer may specify the grade of engine oil in your owners manual, and you should realize that motor oils perform differently based on typical operating environment temperatures. In general, thicker oil is used in hotter environments, and thinner oil is preferred in colder weather.  Lower viscosity engine oil may be recommended more commonly in newer vehicles.

Q: When or how often should I change my engine oil and engine oil filter?
A: Some have advocated engine oil and filter changes every 3 months or 3,000 miles.  The California EPA has led a campaign against this relatively short interval in favor of the recommendations of the automobile manufacturer. Manufacturers commonly indicate that an interval of 7,500 miles is appropriate. One important factor is the quality of the motor oil.  Synthetic engine oils provide a higher quality than others through improved stability. Conditions of automobile use are also significant: frequent trips of under 10 miles in which the oil does not reach full temperature may be reason for more frequent engine oil changes.

Q: Which brand of engine oil and which engine oil filter should I use?
A: Numerous brands of engine oil and engine oil filters are available, and consulting your manufacturer’s owners manual will provide recommendations.  Having a reliable and experienced auto maintenance provider will be helpful in making this decision.

Q: Why do I need to have my transmission fluid changed?
A: Changing transmission fluid or transmission oil maximizes lubrication, for protection from damaging friction between moving parts and eventual transmission failure. This procedure is specified at certain intervals by your manufacturer in the owners manual. Automatic transmission fluid change is best done with a transmission flusher by an experienced mechanic.

Q: Is it a good idea to choose an auto oil change shop that has certifications?
A: While certifications don’t guarantee you’ll get better car maintenance or better service at Marin County vehicle centers, certifications are often an indicator of how serious an auto oil change shop is about providing customers with outstanding auto maintenance. Certifications such as ASE (Automotive Service Excellence) and memberships in automotive service organizations show that the car mechanics have demonstrated an increased degree of professionalism.

Q: Is there a difference between independent auto oil change shops and dealership maintenance shops in Marin County?
A: Where you take your vehicle for car maintenance is your own careful decision based on thorough consideration, the shop where you feel most comfortable and where your car receives the best maintenance service. However, keep in mind the differences between independent auto oil change shops and dealerships located in Novato, San Anselmo, San Rafael, Mill Valley and Larkspur and the rest of Marin County. Local independent maintenance shops are free to use any brand or quality of parts they choose. This, along with the fact of lower hourly rates for car maintenance, can mean big savings.

However, dealerships may be superior in training on newer makes and models. Many newer cars are also still under warranty, and this means some maintenance can be done for free at a dealership. It may even be the case that having warranty maintenance done at an independent automotive maintenance shop will void existing warranties.

Q: Is it really important to take my car to a local shop for regularly scheduled maintenance? Isn’t that just a way for them to make more money?
A: Routine auto maintenance is costly but important.  Engine lubrication in particular is essential.  While it makes sense to achieve cost savings wherever possible, for example by the use of engine oil change and engine filter change coupons, it is important not to disregard routine car maintenance.  A small investment in preventive auto care preserves and protects the large investment you have already made in your vehicle. Be aware of the maintenance schedule in your owner’s manual, and let your trusted local Marin County auto oil change help you with regular car maintenance to protect your automotive investment.

Q: Routing car maintenance is so expensive. Can’t I save money by going to a discount auto oil change garage in Marin County?
A: There are always ways to maximize savings in auto maintenance, and you should be careful to choose an engine oil change price that is prudent and economical. Remember however that a lower engine oil change price may reflect a lower quality job, and be sure  the auto oil change shop you have chosen is reliable for the automotive maintenance services you need.  Remember the assurances available from a Diamond Certified auto oil change shop.

Q: Is there a reason I should request OEM parts instead of aftermarket auto parts?
A: Because aftermarket parts are often cheaper than OEM parts, some auto oil change garages in Marin County install them to lower car maintenance prices. Your mechanic should be able to explain the choice of auto parts for reliable and cost-effective car maintenance.
