then why wouldn you just get a good tune on 92 octane? +1 or 2 octane from 92 wont be that much of an improvement if you have a good tune on the 92....

sure it will help a little but not worth the power to money imo...

and im sorry but unless you have a serious hookup in the long run ( unless your race gas is like $10 a gallon ) the paint thinner is still not cheaper...

race gas is $8/gal here

XYLENE	resultant octane rating
10%	94
20%	97
30%	99

Buy it in 5 gallon buckets its cheaper or 55 gallon drums way cheaper


Mixing E85 with 93 works to. I only know 1 place with e85 and thats about 25min away.

mixing 10% only gives you an octane rating of 92.8
mixing 20% only gives you an octane rating of 93.6
mixing 30% only gives you an octane rating of 94.4

a good blend of "E42.5" would be comparable to 98-100 octane.... Maybe not so much in a n/a car but in a boosted application it would be at least that.
