With the shortage of premium, has anyone tried a mix of toluene? I remember reading about it before and used it at the track 3 years ago. I figured it may help since I did end up spraying that day
Currently, I have about 2-3 gallons of 93 left. I figured I can make a mix with 87 and toluene. If I did it now, it looks like I could end up around 95 octane.
