$1.77 for regular in far, eastern Maine. $1.87 for super, which is what I was told I should put in my 914. From what I'm reading, I shouldn't have to?

The octane rating is ROZ/RON where as pump octane is calculated as (R+M)/2. The label inside my porsche shows the method used; with a 91 as the number. The factory sticker is for RON only where as pump octane is an average of RON and MON ((R+M)/2). If your engine is not stock and of higher compression or not properly cooled and running warm then more octane may be required but a stock engine (4 cylinder, I don't have a six so I don't know sixes) with proper cooling shouldn't require any higher than 87 octane rating. If you've got the european domed pistons, your compression ratio is higher, thus it may require higher octane to reduce preignition. If you're positive about the timing and you do have a higher compression ratio than stock - you may experience preignition with "regular" and thus need a higher octane but bearing in mind the price of gas I would check out the mid grade.



Octane does not prevent the fuel from burning per say, it prevents uncontrolled burning. With proper compression, cooling and timing you won't have to waste money on higher octane to get the proper performance from your engine. OCtane also isn't "magic" stuff that makes cars faster. I hate the way the market gas...
