how's work going Ian any better?
Grockle or Dave, do either of you have a chart or similar, demonstrating compression ratios and octane required?
I'm going to call it a night Grockle, off to read for a while to try and aquaint my self with some obscure facts with to catch you out.:p
Night mate.:)
stock pump unleaded should be fine for you ian.
give it a drink of premium if you like and see what that does for it.
when I free up some time I'll break out the wash bay at work for you and degrease your engine so maybe we can find the info on it.
wish my camera was working yesterday evening .
I was watching a great sunset from the front of the house and a lightning storm from the back.
Thanks Dave and Grockle, the info I was not specificly for my car, more general, and out of interest. I have found that premium fuels used in this car only cost more for nil economy or power gains. I found the opposite to be true in a 3.8L Commodore, which has a 9.4:1 compression ratio. The Commodore would run happily on ULP (91 octane) but considerable economical gains could be found by using BP Ultimate (98 octane high density) on highway cycles.
