the last time that i filled up 100oct at the pump was over 3 months ago. that that time, it was under $6.00
I use a product called Torco. Its not a "octane booster" even though thats what it does. They call it a race gas concentrate. Either way, I know it works. We use it in a 1.8T, and we do data logging, and we set timing, and boost, and with the Torco, we can increase both, and we log timing, and we don't see it get retarded. its good stuff. 1 $20 bottle will make ~10 gallons into 100octane. (roughly, I forget the actual numbers).
Its more for ease of use, and for those that don't have 100oct. at the pump.
