I accept the knock retard sensors will allow better use of premium but I have to say, "so what?" A tad more power on the 80 is like a tad more fat on a 500lb man's neck... no one's going to notice and it doesn't make any differnce if you do.
Blue Phoenix,
premium isn't any "cleaner" than regular. It doesn't clean the engine any more than regular. That is a function of additives. Higher octane makes the fuel more difficult to detonate (thus less knock and used for high compression engines).

Thats exactly right. I maybe wrong, maybe right, but I consider the lower grade of fuel closer to Diesel. And guess why Diesel is so efficient?
The higher grade was explained to me as a harder to burn fuel. In high performance HIGH COMPRESSION RATIO cars, the ping you hear of low test is the gas combusting before the spark a few degree's before TDC. The "high test" lets the engine get to max timing before the ignition. Like Diesel the low test will combust (NOT ignite) with higher compression ratio's....PING!
