"Marvel Mystery Oil provides vehicle owners the ability to solve scores of automotive ailments with one product that can be added to both oil and fuel -
Improves Compression, Power & MPG
Lubricates Upper Cylinder for Smoother Idling
Keeps Engine Clean from Sludge"
Use judiciously because the loosened varnish particles will get stuck in the oil pickup tube & oil won't reach the top of the engine readily.
