Rated 5 out of 5 by from Works! Works! Works! I used this in a VW powered Sand Rail that sat for two years and barely ran (no idle or top end). After about twenty minutes of 4oz of Mechanic in a Bottle in 3 gal of gas it ran like a champ and idled smoothly. Have been using it in everything I have since(Rhino, Jeep, Ford Explorer, Chev 2500HD, Honda Generator} Heartily recommend it!!!

Rated 5 out of 5 by from It really works as they say! Love the stuff. After viewing how it removes carbon in the shop I now use it for all my combustion motors.

Rated 5 out of 5 by from Great Product This product worked great. The pump was not in the box I received so I called Home Depot and they had the manufacture send me a pump. Thank You Home Depot

Rated 2 out of 5 by from Missing pump, missing info from item description As another buyer experienced, the product did not come with the pump despite the directions on the side of the bottle stating that you should use the included pump to measure out each ounce. I was a little disappointed with this product. The Home Depot website says that it "revitalizes old fuel" and cleans all the parts. Unfortunately, the side of the bottle says that you need to remove all old gas if your engine won't start. Home Depot should add the information to their site so customers know what they're in for. As it is, I bought this product for the ease of getting a moped to run with minimal work. Now I need to figure out how to take the moped apart so I can drain the gas first.
