What Can I Put in My Car to Stop an Oil Leak?

by Jeff Dickinson

In higher-mileage car engines, seals and gaskets are bound to lose their ability to keep oil from leaking. There are a variety of products that are available at auto parts retailers that will help an engine's seals become more flexible to stop oil leaks. These products can be added directly to a car's oil case and will begin working within several hundred miles of normal driving.

Lucas Heavy Duty Oil Stabilizer

Lucas Heavy Duty Oil Stabilizer is one of the best-selling oil supplements in the United States, according to Auto Barn. The product, which is added to your engine oil, has been proved to increase oil life by 50 percent. Lucas Heavy Duty Oil Stabilizer also reduces or eliminates oil leaks, depending on the severity of the leak. One bottle (1 quart) sells for around $10, and it is adequate for an engine that has a 5-quart oil capacity. Lucas Heavy Duty Oil Stabilizer will also not void auto manufacturer warranties.

White Shepherd Stop Leak & Conditioner

White Shepherd Stop Leak & Conditioner bonds to just about any engine material, including plastic, aluminum, alloy and metal. It seeps into an engine's seals and causes them to expand. One 8-ounce bottle of White Shepherd sells for around $20, and it treats up to 8 quarts of engine oil. White Shepherd is added to the oil crankcase, and it begins to seal oil leaks as soon as a vehicle is driven.

Bar's Leaks Engine Oil Stop Leak

One 15.5-ounce bottle of Bar's Leaks Engine Oil Stop Leak will treat up to 6 quarts of oil in a vehicle that has an oil leak. Bar's Leaks is added with a car's oil to replenish an engine's gaskets and seals. For around $5, one bottle of Bar's Leaks will begin to seal normal oil leaks within 250 miles after it is added to an engine.

Bardahl No-smoke Plus Stop Leak Oil Treatment

Bardahl's No-Smoke Plus Stop Leak Oil Treatment will rid an engine of smoking due to minor oil leaks. Bardahl's 16-ounce bottle of oil leak treatment can treat up to 5 quarts of oil. It is added to an engine's oil to cause seals and gaskets to swell to eliminate leaks. Bardahl's oil leak treatment sells for around $6.
