The old rule of changing oil every 3,000 miles is outdated for most modern cars. Many manufacturers now specify intervals of 5,000 to 10,000 miles or more, often with an oil-life monitor.

But the right interval depends on your car and how you use it.

Follow the manufacturer

Your owner’s manual lists the recommended oil type and change interval. Using the correct specification matters — especially for modern engines with tight tolerances and turbochargers.

Severe service conditions

Many manuals specify a shorter interval for “severe” use, which can include:

Frequent short trips where the engine does not fully warm up
Stop-and-go traffic
Towing or carrying heavy loads
Dusty roads or extreme temperatures

Time matters too

Oil degrades over time even if the car is not driven much. Most manufacturers recommend changing it at least once a year regardless of mileage.

Check the level between changes

Check the dipstick (or electronic oil level) every few weeks on a level surface. Some engines consume a little oil between services. Running low can cause serious damage.

Change the filter too

The oil filter should be replaced at each oil change so contaminants are not left circulating in the fresh oil.

This is general automotive information, not professional mechanical advice. Always follow your vehicle manufacturer’s specifications and service schedule, and have brakes, steering, tyres, and other safety-critical systems inspected by a qualified mechanic.
