No data, but you are welcome to call and talk to any of the small engine repair shops in this area. It is hard to even get a lawnmower in as they are so loaded with small equipment that is full of rubber sludge and some corrosion. As for myself, all I had to do was look in the fuel filter, I use a clear glass one with the changeable screens. Also seems strange that they want more fuel mileage and then add something to it that causes it to drop. This I have proved by using the pump gas and then using the 93 octane with NO Ethanol in it. Everything runs better, goes farther, and no problems.
