Review: Good deal. - Good product. Makes my truck run better and better MPG
Review: Works Good - I bought it for use in my car. Worked well however with more research I had found Mitsubishi considers MMT which is found in this product to be a low grade booster and they suggest you do not use MMT in their vehicles. Their words. To use up the case I am using it in my lawn mower and tractors. In a 23 HP B&S engine it works well and tamed the harsh engine and takes very little as the tank is only 2 gallons. Only took about 15 minutes to see the results on a well maintained mower. I think I will go with Gunk as it has no MMT for the Mitsu.
