Marvel Mystery Oil Oil Additive, 1Gal, Red, Transparent

MMO is great for carbureted engines, the mineral oil and paint thinner in it leaves a film that breaks down engine deposits and lubricates the top end when you add some to the gas tank. It quiets down my motorcycle and snowblower valve noise. It's no miracle in a bottle, but it serves it's purpose.

Great product

Worked good got my atv running good

Must have product for oil and fuel additive!!

Good stuff

Purchased this from Amazon,and because there so big, why would you have to price shop. Do yourself a favor, and Buy it from WALMART- Its half the cost, same product. Price being addressed first, now thats done, the stuff works for me. Ive been using it in my 2004 Tacoma and my 2007 Acura. I do run a higher concentration than called for, but its because I gradually added more at every tank full until I found optimal return on investment. Meaning, Most MPG for least amount of product. I add about 25 oz per tank Fill... And I get anywhere from 2 to 3.3 MPG increase. And I get that same result range in both vehicles. For a few tank fills, I actually added 30oz, and the fuel increase was the same as 25oz. SO I add 25oz now. Dollar cost average, It is cheaper for me to add this to the fuel and gain additional miles, it is cheaper than the extra fuel at a lower MPG. My Testing was done over an extended period of time... a few Months....., and probably 5 gallons of MMO was used during my test. I consistently used the same exact gas station near my home, Same station, same 93 octane, also driving to the same job, commute on same roads, and the same 120 miles per day. The product produced positive results for me. Ive tried sea foam, and about 6 other varieties of engine additive, cleaner, and Marvel Mystery Oil is the one that produced the best results. The other brands did not even produce a positive result on any consistent basis.

A well proven vehicle lubricant!

Great product very good quality
