How often on average should you change the oil in your car? ›

Depending on vehicle age, type of oil and driving conditions, oil change intervals will vary. It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles.

Explanation: The equation that can be used to find the sale price, s, of an oil change is option 3: s = 0.85 (30). To calculate the sale price, you multiply the original price by 0.85 (or 85% of the original price). In this case, the known value is 30 (the original price) and the unknown is s (the sale price).

However, it's generally recommended to follow the guidelines provided by your vehicle manufacturer. Most car manufacturers suggest an oil change every 5,000 to 7,500 miles or every 6 months, whichever comes first.

Generally, it is best to follow the oil life indicator provided by your vehicle's onboard computer, as it gives a more accurate reflection of your oil's condition. However, if your vehicle doesn't have an oil life monitor, adhering to the mileage recommendations in your owner's manual is a reliable method.

Your owner's manual lists the required oil viscosity (the thickness of the oil), the engine's oil capacity, whether your vehicle takes conventional or synthetic oil, and exactly how often to change your oil. These are the key factors that affect the cost of an oil change, and they vary from vehicle to vehicle.

That means you need to take both figures into consideration. It would be best thought of as “3 months or 5,000 miles, whichever is sooner”.

“While synthetic generally holds up better and can serve for more miles, it is equally important to not extend oil changes beyond the time interval recommended by the manufacturer, typically six months or a year if it is a motor that is not driven many miles or on many short trips.”

Most manufacturers don't recommend leaving the same oil in your engine for more than a year. After interviews with oil experts, mechanics and automakers, one thing is clear: The 3,000-mile oil change is a myth we need to lay to rest.

Can I go 10,000 miles on synthetic 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.
