Anyone tried these? I tried them on motorcycles in another life...not sure if I want to experiment with my passenger vehicles :confused: Anyway, after reading Hacks thread on his 100 octane fuel, just curious if anyones had any experiences with Octane boosters.

Which brings up another question: If you ran 110 octane, any chance of burning "too hot"?
I may be totally wrong about this, but I was under the impression that higher octane fuel makes combustion engines run cooler.

I also thought the reason for cars "these days" having lower compression ratios was due to the lower octane fuel, i.e., cut down on the compression to deal with the lower rated fuels so avoid over-heating.

Am I horribly mistaken?

I had a very radical 2110cc engine in one of my Beetles and I had the heads cut for a 11:1 CR. I found out quickly that unless I could find at least 99 octane gasoline, I would need to rebuild that engine about every 10,000km. Of course, heat is a killer in an engine that is cooled by air and oil.
