What sort of additives do you put in your car?

Answer by  Rickrock (107)

I use lucas oil heavy duty oil stabilizer. It slows down the breakdown of the engine oil. I also use Marvel mystery oil to lubricate and keep the gas lines from gumming up. They both work well.

I don't put any additives in to my car. And I don't think additives do anything good. If you buy a good car it won't need any additives to put in it.
