This stuff is crazy good although I need to replace injection pump on my Mack 350. This product made the truck run the best it has done for a year. Almost made me forget the pump. Suggestions for a new pump? -- Peter P. via Amazon (Verified Purchase)

Just prior to winter in 2012, I used 1/3 an ounce of Cerma engine treatment in my 1999 Craftsman snow blower. In the past it was necessary to have the choke on and to let it run a bit before using, especially in really cold weather. Even at that, it sometimes took a couple attempts ...

The boat is going over 28 MPH. Granted clean bottom and props but I don’t believe it ever went over 26ish on this boat. It is a 40 FT Meridian Yacht weighing 17 tons. Top end speed was increased about 10% and that is before we start with the CERMAX Motor Oil.
