3 Tips for Preventing Engines from Becoming Sludgy

Updated on December 24, 2017

Car owners need to be careful of engine sludge. This is one of the most common problems that car owners see. Motor oil can break down and thicken. They then accumulate contaminants and become a sticky goop that can damage engines and cause them to overheat. In worst case scenarios, engines can become so damaged that they need to be replaced. Here are 3 tips and tricks on how to prevent sludge from accumulating within engines.

Avoid Excessive Idling

Unknown to most drivers, excessive idling can actually be damaging to their engines. Short commutes that are less than 10 miles in length can actually encourage sludge to buildup within the engines. This is because the engines are constantly being turned on and off; however, they are not driven enough to reach their ideal temperature.

As a result, the motor oil within the engines cannot flow properly throughout the various parts and eventually become sludge.

Use the Right Gasoline and Oils

Another common reason for sludge buildup is the improper use of engine oils and gasoline. The wrong fuel or oil can cause an abundance of problems to emerge in the engines, which is why most dealerships recommend getting professional help when changing the engine oil.

It’s also important to avoid off-brand gasoline as much as possible. Studies have shown that they can cause as much as 19 times more contaminants to accumulate within the engines. Car owners looking to get more information should take a look at their owner’s manual. The manual should provide in-depth information on the various types of oils that are considered appropriate.

Get Regular Oil Changes

Proper maintenance of each vehicle also prevents the engine from getting sludgy. Car owners looking to protect their engines should get regular oil changes and maintenance. This is essential for enhancing the performance and lifespan of engines. It also prevents the engines from overheating, especially when the vehicles are taken out for long drives.

Look at the owner’s manual to get a better idea on when the cars need to go in for servicing. Dealerships should also be able to schedule all of the services ahead of time, and will also remind car owners to bring their vehicles in. Speak with the technicians to get a better idea of the type of oils they use. Some are better for the engines than others.


With proper maintenance and care, car owners are able to prevent their engines from accumulating any sludge. This will lengthen the engines’ lifespans and will also improve their overall performance. They are less likely to overheat with time, and will require fewer repairs in the future as well.
