I think I might need a little help, I always thought octane rating had more to do with the compression of ones' engine. I have seen some replys that mentioned altitude. I do know one thing, the older version of my airplane used 80/87 octane fuel at altitudes up to 13,000 ft and my version uses 100LL(low lead) at altitudes to over 14,000 ft, both of which are low compression, so what am I missing here? By the way the push is on from the feds to make low lead fuel a thing of the past for the low compression aircraft engines.
