Lucas Oil Products High Mileage Oil Stablizer (1 qt.)

I like the Lucas products because it's been around for a long time. I used the Lucas oil additive every third oil change. it's very easy to use, just add half of the bottle contents while the engine is warm. I used the Lucas fuel additives when my gas gauge is at half tank to clean the fuel system more effectively, up to the injectors and valves. it doesn't give you engine performance, like it will not make car go faster. but it will clean your injectors and valves.
