Dear Team Buick members, :shield:
I'm trying to settle upon the compression ratio for the Buick 430 engine that I'm starting to have rebuilt. After getting many helpful lessons from the gurus on Team Buick, I know that I cannot push the dynamic compression ratio too high or the engine will suffer from premature detonation. However, that in turn depends upon octane quality of the available gasoline. After cruising the Internet a bit, I've found that in the United States the accepted threshold for premium is only 91 octane. In California that is the highest commonly available octane since 2004. Nonetheless, according to folks on V-8 Buick, there are still many parts of the country that have 93 octane gasoline.
Now that I've found how to conduct a poll on this new forum software, I thought I would ask folks on Team Buick about what sort of premium gasoline they have commonly available around their neighborhood. Please do post a comment to this thread if you know something about this topic that would help folks assess what kind of gasoline to expect in the future for our high-performance engines.
Thanks in advance for participating!! :thumbsup:
Cheers, Edouard :beers:
