Everyone I have a question. Exactly is Marvel Mystery Oil used for? Does it function as a motor oil life extender a fuel treatment an engine flush or all 3?
Ben Otto: Its a low viscosity oil with detergents in it. Back before oil had so many additives, people would use it to flush sludge from engines. Almost all oil has its own detergents now and marvel mystery oil isnt nearly as useful. But Ive kept it around for a few things. Ive add some to differentials to reduce friction. Used it as a 2 cycle oil in a pinch. Ive used it to diagnose a bad fuel pump. Sometimes I spray some into an old oil free air compressor I have because the cylinder is scored on it. A little marvels keeps it running for another year.
Ben Otto: Plus it smells good ðŸ‘
