Description
Marvel Mystery Oil lubricates the entire fuel system-fuel pumps, fuel injectors or carburetors and the top-portion of the cylinders. Using Marvel Mystery Oil in your fuel extends the life of these vital components by providing them with lubrication that fuel alone does not provide. It reduces and prevents varnish and gum build-up, two key contributors to robbing engine performance. Marvel Mystery Oil creates a cleaner burning cylinder environment that reduces carbon build-up on spark plugs, extends spark plug life and improves fuel mileage.
