The question of how often used cars should get an oil change depends on a number of factors: type and age of the vehicle, what kind of motor it has, and driving style and usage all come into play. The good news is that not only is oil service a ​quick, affordable, and simple ​service, but it’s also one of the best ways to keep the heart of your car running smoothly and performing its best for years to come.

Mileage, Months, and Usage

Your car should have a sticker from its previous oil service with two indicators: one for a mileage at which to change the oil, one for the date at which the next oil service should be scheduled. It’s important to change the oil whichever comes first and not to wait for both. Oil degrades both with use and with time. Additionally, your vehicle’s owner’s manual will have guidance on oil type, change frequency, and more.

The Importance of Clean, Fresh Oil and Filters

Motor oil performs several crucial functions in your car’s engine. First, it helps cool the engine, preventing overheating. More importantly, it lubricates the moving parts, ensuring smooth operation. It also helps remove any particulate buildup, including tiny metal shavings, contaminants, and more, which then is filtered out by the oil filter. When oil is left in a motor for too long, it can cause sludge buildup and damage, and if it runs out, the engine can seize, necessitating expensive repairs.

Conventional, or Synthetic?

Both conventional and synthetic oil have their advantages. Conventional oil is more affordable, though the longevity of synthetic oil tends to offset this. Synthetic oil may be a better choice if you drive hard or drive off-road, experience extreme heat or cold, spend a lot of time in traffic, or if you tend to take short trips (since synthetic performs better in cold engines). Your maintenance team can help you make a great decision either way.

Your Car Shouldn’t Burn Oil

No matter how old your car is, an engine burning through an excessive amount of oil isn’t normal. If you find yourself putting in quart after quart between changes, there may be something else wrong. Be sure to tell your technicians if your engine burns through oil so they can correctly diagnose the problem, whether it’s a slow leak, a valve stem issue, or something more serious.
