The owner'w manual for the TR8 calls for 93 octane fuel, but at a CR of 8.15:1, I can't imagine why the high octane is needed, especially with aluminum heads. With premium gas getting close to $4 per gallon, I really have to question whether the extra octane is really necessary. I've run mid-grade with timing advanced to the max with no apparent preignition but it's the things that aren't apparent that make me question the lower octane.
Any thoughts on this?
