Oil System Cleaner

Economically removes soft sludge build up from your engine, improving fuel economy and extending your engine's life.

Oil System Cleaning Removes Harmful Sludge Deposits

"Sludge" is the name of a very thick & sticky, tar-like substance that forms inside your car's engine as a result of normal vehicle use. Deposits of sludge inside your engine can restrict oil flow and movement of engine parts, and over time can create the need for expensive engine repairs.

Our Oil System Cleaner removes softer sludge deposits from your vehicle's engine. When performed regularly, your car or truck will start more easily in the morning and you'll get better gas mileage on the road. Most importantly, regular oil system cleans will help extend the life of your engine without major and costly repairs.

Does My Vehicle Needs an Oil System Cleaning?

Is your car past due for an oil change? If so, we recommend an Oil System Cleaning service to remove early sludge deposits that may have formed.

If your car or truck's oil system has never been cleaned (or it's been awhile), we recommend either an Oil System Cleaning or a full Engine Cleaning service to remove more advanced sludge deposits.
