How Often Should You Change Your Oil? Quick Tips:

  • Follow guidance in your car’s owner’s manual regarding how often to change the oil.
  • The type of motor oil used determines how often oil changes are needed.
  • Changing your oil and filter every 3,000 miles is an old-school habit for conventional motor oil.
  • Synthetic blends and fully synthetic varieties can last 5,000 miles and up to 10,000 miles between oil changes.
  • High-compression engines, auto start and stop technology, turbocharging, and more have put increasing demands on oil and lubricant technology.

Some car owners say oil changes are similar to heading to the dentist for a biannual cleaning. It’s an inconvenient task but necessary maintenance for longevity and preventing future problems.

Once upon a time, local service stations and oil change franchisees recommended changing your car’s oil and replacing filters every 3,000 miles. That rule of thumb might have come partly from a marketing ploy. No matter, today’s synthetic blends or fully synthetic motor oil often last two to three times as long as conventional motor oil.

How Often Should You Change Your Oil?

Engines with newer technology often use synthetic oil and can travel 5,000, 7,500, and even 10,000 miles between oil changes. While more exacting standards in engine-building tech are now in play, the quality of synthetic oils has also improved.

Your owner’s manual has the manufacturer’s suggested oil change schedule. Still, there are also general recommendations regarding oil change frequency based on many factors, including your driving habits and location.

Drivers in the United States travel about 12,700 miles annually. So, if you’re average and log about 6,000 miles every six months during your excursions around town, it’s probably good to get an oil change twice a year. More frequent oil changes might be needed if you do a lot of highway or long-distance driving, or if you drive in sandy or dusty surroundings like the deserts of Nevada or Arizona.

An oil-use monitoring system is a helpful bit of technology that can help keep your oil changes up to date. About half of today’s new cars have this feature that will notify you when it’s time to change the oil.

Why Is Changing Oil Important?

Engines have made quantum leaps in technology. How we lubricate them has remained a constant, and the need to keep that oil clean helps ensure a long engine life. That involves periodically draining the used oil, replacing the oil filter, and refilling the engine with new lubricant.

High-compression engines, auto start and stop technology, turbocharging, and more have put increasing demands on oil and lubricant technology.

Types of Motor Oil for Your Vehicle

Several types of engine oils are on the market. It is widely available at your dealership, service center, auto parts shop, or big box stores. Motor oil varieties are tailor-made for the vehicle type and your driving habits.

Conventional oils are derived directly from crude oil. Newer synthetic oils blend traditional oil with lubricants and other additives that enhance its performance but come at a higher price, on average, than regular oils.

Should I Use Synthetic Oil? 

Any car with a gasoline engine can benefit from using synthetic oil. (Electric cars do not use any oil.) Only a few vehicles require synthetic oil. Synthetic engine oil and blends cost more than conventional oil. Still, drivers may save money over time by using a synthetic variety because it lasts longer, requiring fewer oil changes.

To decide what type of lubricant is suitable for your vehicle’s engine, it’s best to consult your owner’s manual. Inside it, you will find the type, grade, and guidance on how often oil changes are needed.

How Heat Affects Motor Oil in Your Car

Regional temperature fluctuations have always been a moving target. And they can affect the duration of your motor oil’s effectiveness. Your local auto shop will help you select the proper grade of oil for your vehicle to be sure it gets what it needs. Where you live and how you use your vehicle are just as important as how much you drive.

The introduction of higher temperatures can cause oil to break down sooner than expected. At the same time, wind-blown sand and grit can get into the engine, especially under extreme conditions.

Oil Change Cost Factors

A typical conventional oil change and filter replacement will run in the neighborhood of $60 to $85, depending on which neighborhood you live in, of course. You can use our Car Maintenance Pricing tool to find the estimated cost of an oil change for your vehicle in your area. Using synthetic oils may increase those prices by $20, give or take.

Doing it yourself will save a considerable amount of money when you need to get an oil change. Depending on your location, five quarts of conventional motor oil and an oil filter will cost around $35. The same amount of synthetic motor oil and a new filter will cost about $50 plus tax.

Check local auto parts suppliers and service centers for specials.

What’s Involved in an Oil Change?

Your local dealership service department knows your vehicle best. Its technicians have undergone factory training to properly maintain and repair your car, truck, or SUV. While traditional oil is still widely used and likely was in your vehicle when it came from the factory, your dealership service department stocks a range of brands and oil types. Your service advisor will suggest the oil that will suit your vehicle’s needs.

Many vendors, such as a dealership express lane or quick-lube shop, advertise “in and out in 30 minutes or less” for oil changes. Our experience tells us to set aside an hour for the service.

If you plan to perform an oil change yourself, consult the owner’s manual for oil type and amount, oil filter size, and the location of the oil pan and drain plug.

Do-It-Yourself Oil Change Tips  

  • Park on a flat, level surface. Apply your vehicle’s parking brake and turn the engine off. If needed, raise the front end of your car with a pair of jack stands. Open your hood and remove the oil dipstick to allow complete oil drainage from the crankcase.
  • Make sure to wear safety glasses. Once your vehicle is secure on the jack stands, crawl under and move to the engine’s oil pan. Consult the manual for the location.
  • Locate the drain plug at the bottom of the plan.
  • Position a catch pan under the drain plug. Make sure it is large enough to capture all the oil draining from your engine. Check the manual for oil pan capacity.
  • Using the proper socket wrench or box-end wrench, loosen the drain plug over the catch pan to flow the draining oil into the pan. CAUTION: The oil may still be hot!
  • Inspect the drain plug for any stripping of the threads or the bolt itself. If it is okay, replace it once the oil has completely stopped draining. If in need of a replacement, hopefully, you will have already acquired it. Tighten the plug with the wrench used to remove it.
  • Locate your oil filter. Have your oil catch pan ready in case of any residual oil remaining. Loosen the oil filter with an oil filter wrench. Check the gasket to make sure it was removed with the filter. Replace with a new filter after applying a coat of oil to the new filter’s gasket.
  • Remove the oil filler cap and pour the proper amount of fresh synthetic or conventional oil back into the engine, using a funnel to avoid spillage. Replace the cap.
  • Start the engine, letting it idle for at least a minute. Check underneath for any leakage. If all is good, turn off the engine, and lower the vehicle by using the jack and removing the jack stands.
  • Check the oil level using the dipstick once on solid, level ground. Use the oil dipstick as a gauge. Add additional oil if necessary.
  • Properly dispose of old oil by taking it to your local dealership service department or auto service center to be recycled.

Consistent routine maintenance can enhance the resale value of your vehicle in the long term. Any potential buyer will appreciate your diligence in taking care of the car.

And in the short term, you can rest assured that your vehicle will be ready to go when you are by keeping the oil fresh and clean.
