[QUOTE="JB08, post: 100068, member: 2221"] Back a few years ago when premium hit $1.50 here in Ontario, I decided to experiment with regular gas on my Acura (premium is recommended). The use of regular results in false savings because I clearly saw a decrease in fuel economy and power. I am not technically savvy enough to explain why, but I assume the timing difference in combustion that results from the octane difference results in a degrading of efficiency and power. I don't think it does any harm to the engine (at least in the short to medium term). While I may be willing to accept that on my DD, no way I will do that with my C7. [/QUOTE]
