I use klotz octane booster, it is $56/gallon (you can get 5 gallon cans cheaper) and for every 1oz of octane booster per gallon of gas it raises your octane by 2.5 numbers (93 octane to 95.5 octane) and it is actually SAFE to use unlike the toluene. You can also use torco octane booster but it costs a little more. The stuff you buy at autozone etc is garbage it raises octane in points as in (93 octane to 93.1 octane) which is a waste of money.
i've been trying to read up on it here and there, and this is the first mention of negatives. other things ive seen have quoted that its safe on o2's. i haven't seen anything on seals, although i've seen reports of it being used by manufactuers and race teams. i'm not questioning you, but trying to get as much knowlage as i can about it before i try. my main concern is fuel mileage and power loss on hot days in traffic. the klotz booster, does it show improvements like these? i'm sure it would help with the car pulling timing with the octane raise.
just to add. at $56/gallon and using 1oz/1gallon at 16 gallons a fillup, i get 8 fill ups a gallon of klotz and that would come out to an additional $7/fillup to my current fuel charge. thats just under two gallons of gas so for benefits that would mean i would need to gain over 60 miles more range per tank.
i dont know the cost of toluene, but replaceing gallons of gas w/it, could end up being cheaper if increased mileage is achieved
