I know the military buys this product in 55 gal drums, and uses in vehicles.

Thoughts ?
I sometimes add about a half-pint of Marvel Mystery Oil to the gasoline tank to keep the valve area at the top of the 4-cyl engine clean from oil grunge build-up. MM-Oil is a detergent that cleans the inside of carburetors/injectors and valves. It is owned by Turtle Wax which is a very reputable car care co.

For small engines like lawn mowers, snowblowers, and outboards that get stored away for months, it's good to put some in the gasoline and run it before storing it away.

What's a bad thing to do is to add MM-Oil to the oil if you use synthetic oil because MM-Oil and synthetics do not combine and mix together. They stay separate and somehow co-exist within the engine?
