Oil Change Types Compared

Below is a helpful table summarizing key differences between DIY and professional oil changes:

When to Get an Oil Change on a New Car

Routine oil changes are essential even for new vehicles, although modern engines and high-quality synthetic oils often allow for extended intervals. Most manufacturers recommend completing the first oil change between 5,000 and 7,500 miles, but owners should consult their specific vehicle guidelines for accurate maintenance schedules. After the initial service, typical oil-change intervals range from 7,500 to 10,000 miles when using synthetic oil. However, drivers operating under severe conditions such as frequent short trips, towing heavy loads, or driving in extremely hot or cold temperatures may need to change their oil more frequently to maintain optimal engine performance and longevity.

Common Mistakes to Avoid When Changing Engine Oil

Avoid these common errors to ensure your oil change is done correctly:

• Using the wrong oil type
• Overtightening the oil filter or drain plug
• Not replacing the oil filter
• Leaving the old drain plug gasket on
• Overfilling the oil
• Not checking for leaks afterward

Making these mistakes can lead to leaks, engine damage, or costly repairs.

Signs Your Car Needs an Engine Oil Change

Here are the signs your car needs an engine oil change, listed in points:

• Burning oil smell inside or around the car
• Engine knocking, ticking, or other unusual noises
• Rough idling or unstable engine idle
• Oil on the dipstick appears dirty, dark, gritty, or sludge-like
• Oil level consistently low when checked with the dipstick
• Dashboard oil pressure or oil-change warning light turns on

If you notice any of these, it’s a good idea to check your oil and consider getting an oil change even if your scheduled maintenance isn’t due yet.
