4 Types of Damage That Can Happen When You Don’t Change Your Oil

Posted July 2, 2024

Changing your engine oil regularly is one of the easiest and most critical maintenance tasks for your vehicle. But it’s tempting to let the months and miles slip by, postponing this essential service. Ignoring those oil change reminders for too long can lead to major mechanical problems. Don’t learn this lesson the hard way. Stay diligent about oil changes at the manufacturer’s recommended intervals to avoid unnecessary and costly damage.

1. Engine Sludge Builds Up

Fresh, clean oil keeps all the components of your engine properly lubricated and running smoothly. When you don’t change the oil on schedule, contaminants and particulates that cause sludge build up over time. This old, thick oil cannot properly lubricate the many complex, precision parts under your hood. Without regular oil changes, your engine is at serious risk for accelerated wear and tear.

2. Oil Leaks Become More Likely

The oil seals and gaskets in your engine are designed to keep oil contained in the proper areas. However, extended use of old, dirty oil can cause these components to degrade, dry out, and crack prematurely. Even small fissures create problematic leaks. Catching oil leaks early with routine oil service makes them far less likely to occur.

3. Your Fuel Mileage Suffers

Sludgy, resistant old oil prevents your engine from running efficiently. Your fuel mileage takes a noticeable hit as components bind and your engine works harder against the thick oil. Keep your MPG optimized by sticking to the recommended oil change schedule.

4. Major Repairs Can Sneak Up On You

Ignoring oil changes allows damage to accumulate slowly over time. The gradual wear and tear on internal engine components like bearings, pistons, and cylinders will eventually catch up with you. This kind of mechanical degradation often necessitates expensive repairs down the road. Don’t wait for warning lights to flash before servicing your vehicle. On new cars, experts suggest changing your oil every 5,000 to 7,000 miles, according to The Balance. With older engines, used oil tends to break down more quickly, so shorter oil change intervals are recommended.

Don’t cut corners on basic maintenance procedures like routine oil changes. With regular oil service at the vehicle manufacturer’s recommended intervals, your engine will run smoothly for miles to come. Stay proactive to avoid unnecessary and costly repairs down the road.
