With the gas prices like they are and can be, I have to ask a question. What, if any, would be the long time effects of using the midgrade or low grade octane? Any suggestions on how to fight the high prices. I know that where I live is probably not the highest place on gas right now, but at $2.05 per gallon, does anyone have any idea on how to beat it? I have thought about going to the lower grade and using octane boost, but I don't have enought data yet to determine whether it would even save enough to fool with it.
