Rated 5 out of 5 by from A multi-purpose product that excels! Marvel Mystery Oil is a fantastic product! I have used it for years in my automobiles, particularly in the gas. I get better mileage with MMO and it helps neutralize the effects of ethanol being added to our fuels. Its nice to know that it keeps the fuel system clean and lubricated. I also use MMO as a penetrating oil (which it works great for) out of a needle-oiler. MMO also makes a nice gun lube/cleaner for my two handguns and a fuel stabilizer for my generator. Can't beat one product for all those uses.

Rated 5 out of 5 by from This Fixed My Oil Pump My Dad bought a 01 Suburan, and it had an oil pressure problem to where we worried and couldn't keep our eyes off the gauge. Long story short, we changed the oil, added 20% to 5 quarts. It made the pressure go lower, at the point it was in the red zone. After babying it to and from work, since it was the only vehicle at the time, it eventually increased almost back to normal, to the point I wasn't worried about it anymore! It must have been clogged or something since it was a sitter vehicle.

Rated 5 out of 5 by from Boosted my mileage by 3mpg. I used MMO 4oz/10gal gas to pull a trailer to and from Florida/Michigan. In total 2,400miles my mileage actually improved from 9MPG pulling 3,200lb trailer with Chevy 4.6l to 12 MPG by the end of the trip! THREE mpg better! Once unhitched, the mileage stayed better than 17 w/o trailer. Before that it was about 14mpg. I sincerely believe the regular MMO use during this trip helped the overall performance and economy of my truck.

Rated 5 out of 5 by from MMO WORKS ! Case in point. I have used MMO for years. I had a 1995 Toyota Celica I drove in commuting 750 miles a week to work. I used MMO in the gas every fill up. I sold the Toyota in 2014 with 310 thousand miles on it. The man I sold it to let his daughter commute back and to college. He sold the car 2 years later with over 426k miles on it. MMO works, period. By the way, some of the NASCAR boys use it to !!
