Review 1 for Marvel Mystery Oil, 1gal

I work on alot of small engines for a hobby. I also fix and maintain alot of my friends and familys cars. Used alot of additives for the fuel and different oil additives to. (lucas, stp, bardall, tech, etc) But none of them can ever compair to MMO!!! I revived ALOT of mowers, weed eaters, snow blowers, and even vehicles by using it in the oil and fuel. Does a great job cleaning all the carbon out of the injectors, carb, and crankcase! Also it is absolutally a FABULOUS product for preventative maintnance on a car! I only use quakerstate semi-synthetic (conventional mixed with some synthetic) motor oil with a quart of marvel mystery oil. even after 5,000miles when i change it the oil is suprisingly cleaner and holds its viscosity WAY better than full synthetic motor oil!! It was such a great additive that you will find out that in world war 2 the USA and the British used this product in all of their tanks, fighter jets, and carriers! If its that good of a product that even the army uses it and it held up in battles its great enouph for my car! Also its made and packaged in the U.S.A!!! SWEET!

Have been using MMO for 50 years, both in the crankcase and the fuel tank on all my vehicles, cars and trucks new and old. best performance product I ever used.

I have an STC to run ethanol-free auto gas in my airplane and like the previous owner did for over 20 years, I use 2 oz of MMO in every 10 gallons of fuel and also add a pint in the oil during every 50 hour oil change. During a recent 1,800 hour interval overhaul of the 33 year-old Continental O-200 engine the A&P mechanic said it looked like a near factory-new engine on the inside. It probably could've gone another 1,000 hours before really needing the expensive overhaul.

Marvel Mystery Oil is the best product for both gas and oil I have ever used. My engine runs smooth and it idles better than ever. I have use the product for about a year and with WalMart pricing I am able to add to my gasoline each filling.
