Engine Oil: How Engine Sludge Forms and What You Can Do to Prevent It

Last updated 5 years ago

To prevent engine sludge from building up and affecting your car’s performance and fuel efficiency, it’s important that you enlist the help of your local car repair shop for routine maintenance and repair. Read on to learn about the causes of oil sludge buildup and how your car repair shop can prevent it from occurring.

Excessive Stop-and-Go Driving

When you drive in stop-and-go traffic, your car’s engine doesn’t get the opportunity to rest. In turn, the engine heats up beyond normal levels, which heats up the engine oil. If your engine oil becomes too hot, it will be more likely to oxidize and turn into sludge, causing engine damage that’s expensive to repair.

Lack of Maintenance

Your car needs to be maintained regularly in order to keep engine oil from turning into sludge. When you go to a car repair shop for an oil change, the mechanics will also change the oil filter, the component that removes contaminants from your engine oil. If this filter is old and clogged, your engine oil will turn to sludge.

Never Letting the Engine Reach Running Temp

Your car’s engine needs to heat up to a certain temperature as often as possible. If you only take short trips around town and the engine never gets the chance to warm up, the engine oil won’t heat up either. This increases the chances of it developing into engine oil sludge over a short period of time.
