I used it in my ZT yesterday and ran it about 3 hours and I honestly felt like it was a kick in the pants. I did start quicker as well. I don't get pumped up easily as I know my equipment very well. I'm going to finish up the tank and see if I'm still getting results. I wouldn't buy it but if it really works I will not ignore the results either. I put it in 87 octane.
