How many miles to change synthetic oil
Knowing when to change the oil in your vehicle used to be simple. There was a common standard: Do it every 3,000 miles. With technologically advanced engines and synthetic oils constantly being developed and reformulated, it’s not quite that easy anymore.

Your car’s engine needs oil to keep moving parts lubricated, especially since the tolerances are minuscule between parts such as the bearings, crank, rings, and cylinder walls. Differing temperatures cause the metal parts to expand and contract, and when those parts are expanded, the tolerances are even tighter. Without a lubricant, the engine might seize. Changing this lubricant — your oil — on a regular basis ensures that it performs as designed.

Synthetic Oil Change Interval

If you are using synthetic oil, the interval between oil changes can be extended. Manufacturer recommendations range from 5,000 miles to 7,500 miles, on average. Some recommended intervals might be shorter or longer. So, how many miles between oil changes is just right? Even when using synthetic oil, it depends on the manufacturer’s recommendations and the way you drive. It’s also worth noting that a full synthetic oil change, while pricier than a regular oil change, is better for the environment and does allow you more time between oil changes.

Determine the Optimal Number of Miles Between Oil Changes

Oil detergents and additives are what break down over time. The additives also prevent sludge from building up, and they prevent corrosion as well. As these detergents break down, the oil offers less protection for your engine.

To answer the question: “How often do I need an oil change?” check your owner’s manual. It may recommend 7,500-mile oil changes when using full synthetic oil and 5,000-mile intervals for oil that is only partially synthetic. Be sure to read all of the material the manufacturer provides, as the way you drive will determine which recommendations to follow. Factors that could affect the recommended interval between oil changes include:

  • Driving less than 10 miles per trip frequently, especially during the cold months.
  • Towing, especially uphill.
  • Frequently driving on gravel roads and in other dusty conditions.
  • Whether your vehicle’s engine is turbocharged.
  • Whether you drive a diesel-powered vehicle.
  • Whether you do a lot of stop-and-go driving.
  • Whether you drive at sustained highway speeds during the hot months.
  • The age and condition of the vehicle.

The owner’s manual will state the recommended oil change interval for adverse driving. The interval could be as low as 3,000 miles if you constantly drive your vehicle in adverse conditions.

Synthetic Oil vs. Conventional Oil

If you still use mineral oil — regular oil — the answer to your question, “When do I need an oil change?” is quite simple: every 3,000 miles. Mineral oil has more impurities and the oil detergents tend to break down sooner than is the case with synthetic oil. This is because synthetic oil is cleaner than mineral oil.

For Longer Oil Life, Turn to STA-BIL

Regular oil changes are necessary, and there’s no replacement for this routine maintenance. However, you can make your oil last longer and protect your engine by adding STA-BIL® 360° Oil Stabilizer from Gold Eagle. This product, when added to the oil crankcase, gives the oil detergents a boost when they are wearing down. STA-BIL 360° Oil Stabilizer:

  • Helps prevent rusting and corroding.
  • Gives the engine more protection at startup, when the oil has drained into the crankcase after sitting.
  • Reduces wear from friction and heat caused by running the engine, especially at higher speeds.
  • Prevents thermal breakdown.
  • Improves the lubrication properties of oil.
  • Lowers the engine’s operating temperatures, which extends the oil life.
  • Reduces wear on the engine.

Add a bottle with every oil change — it is safe for use with all types of oil.

How Long Can You Go Without Changing Your Oil?

How often do you really need to change your oil? We have been told for years that it’s important to change our engine oil “every 3 months or every 3000 miles” so hopefully you’re at least looking for a quick oil change a few times a year, but how long can you go between oil changes?

Do you still need to change your oil every 3000 miles? How long can you go with full synthetic oil? Can your Mercedes really go 10,000 miles between oil changes? Well don’t worry! Today I will tell you once and for all the truth!

Short Answer – It depends….

I know I know, not what you wanted to hear! So, as best I can, here is the medium length answer.

Conventional Oil and Older Cars – 3000 Mile Oil Change

If your car does not require a synthetic blend oil assume 3,000 miles is the rule. On a side note, oil change specials for $19.95 use conventional, so make sure your car is old enough and doesn’t need a blend. Older vehicles were built with older technology and engineered with non-synthetic oils in mind.

What if your car’s a little newer? You may be wondering “how often should I change my oil if my car has high mileage”? If you have a newer car with 150,000 or 200,000 miles you likely should also change your oil every 3,000 miles. If you burn more than 1 quart of oil or your oil is very dark before you get to 3,000 miles it’s likely time to change it! If you’re oil is still medium brown and not low after 3,000 miles you’re in luck! In spite of the high miles you’re engine is in good shape and you can go a little longer.

Synthetic Blend Oil and Higher Oil Capacity – 5,000 Mile Oil Change

Most Oil Changes Use Synthetic Blend Oil These Days

Just about all cars now require synthetic blend oil. “How much more expensive is synthetic blend oil” you wonder? The good news is that the cost is very close. If you’re looking for an oil change near Indian Trail, NC 28079 Kindred Automotive doesn’t even charge extra for a synthetic blend oil change.

Synthetic blends hold up longer and won’t break down, even after 5000 miles of driving. Newer cars also have better filtration systems, allowing you to safely drive 5000 miles between oil changes.

If your car holds more than the typical 5 Quarts you may also be able to safely run 5,000 mile oil changes. More oil means more additives and more storage for the carbon and gas your filter can’t trap.

Synthetic Blend Oil Changes are much better for your engine, and safe for older cars, but you still need to check your oil at 3,000 miles and follow the advice listed above for high mileage engines.

Full Synthetic and European Oil Change – 7,500 Miles to….. well, it’s complicated!

Full synthetic oils will actually last well beyond 10,000 miles. The lifespan of synthetic oil depends, but it’s not crazy to see oils still working at 15,000 miles or longer. Synthetic technology is pretty amazing, but it isn’t magical. Just because the oil additives still work and the oil isn’t breaking down doesn’t mean it’s safe for your engine.

Euro cars like BMW, Jaguar and Mercedes hold 8+ Quarts of Synthetic Oil due to their higher performance and longer service intervals

Over time engine oil gets diluted with gasoline and loses the ability to lubricate properly. Oil also has limited space to suspend particles, there’s only so much real estate to go around! Another complication seen in newer engines is the very tiny passages that oil must travel through, setting the stage for a clogged engine artery and a mechanical heart attack!

How long can your car go using Full Synthetic Oil depends on the amount of oil it holds, how large and how good the oil filter is, how well the engine was designed and how much it has worn over the years. We have seen a huge increase in engine repairs due to “Extended Oil Changes” leading to rapid failures.

Our standard recommendation is 7,500 miles for a normal vehicle based on the thousands of engine repairs we’ve seen over the years. This seems to be the most cost-effective balance of more frequent oil changes and less frequent repairs. Changing your oil sooner than 5000 miles will typically just increase your cost without any additional benefits. Likewise, waiting past 10,000 miles leads to thousands of dollars in future repairs and will not pay off in the long run.

Our personal vehicles hold between 6 and 9 quarts of Full Synthetic Oil and we shoot for every 5,000 miles. That means roughly 6,000 miles when we finally get around to it… Yes, we forget sometimes too! ?

How many miles can I go between oil changes with synthetic oil?

If you own a car that runs on synthetic oil, you're probably wondering, “How often do you change synthetic oil?” Depending on the type of car you have, most synthetic oils last between 7,500 miles and 15,000 miles. However, you'll need to check your owner's manual for more specific figures.

Can you go 10000 miles with synthetic oil?

Change Every 10,000 Miles If your car's manufacturer recommends synthetic oil, or if you decide to make the switch, you could go as many as 10,000 miles or more between oil changes. Though synthetic oil is much more expensive than regular oil, it has more benefits.
