You guys want to know how much added to x gallons will raise it by y then read the link I posted. The information is there.
I would not call MMT a replacement for race fuel. It is to be used as a bit of cheap insurance with pump fuel of questionable quality. Which is basically every tank you get at the pump. That is why some people run it in every tank.
I dumped in 16oz's every other tank just to keep some MMT in there and get a couple octane points or three bump on the pump gas, I'd add another 16oz when I tracked my car.
Worked well for 3 years.
