Hutch let me ask ya this....does it add a tad more timing and change your fuel curve and your spark table...obviously it would burn cleaner resulting in less knock...

running a high octane without the proper tune could result in predetonation if i remember correctly

how would it cause predetonation? how does it pre-explode uncontrollably

anyways running higher octane without a tune for it is a waste, the car will add no timing. you need a tune to add timing.

it burns SLOWER (not cleaner), reducing the chance of knock.

This 'discussion of high octane vs not has been gone through before.
The two sides are far far apart and never the twain shall meet.
As for whether premium has ANY benefits, or not. each person can find out for themselves.
To ASK? it is like howling at the Moon. This is fighting turf..

You should see no difference in milage. only a bigger dent in your wallet. If you are looking for some bang for the buck in all categories try adding some sea foam to your gas. Its the white metal can with red labeling (~$8). You can also fog the engine to clean the top of the valves and the back side of the throttle plate. This will also create one hell of a fog show and most likely kill all the mosquitos in your neighborhood.

Higher octane fuels keep your valves cleaner because the addtives used to increase the octane are the same thing used in fuel system cleaners it has been proven. Its not really a dent in your wallet its actually cheaper than buying an additive and pouring it in. A full fillup in my 2010 only yeilds about 3 dollars more per fill up to use High octane. it costs about 20-30 cents more per gallon over regular fuel. so think if you get ten gallons of gas which is about a typically fill up thats only 2-3 dollars more! that vs $5+ for a fuel additive

Also sorry for the multiple posts, but i tracked and logged 35-45 more miles when using premium over regular. And the factors were the same. it was the same commute this summer 20 miles each way at 45-70 mph speeds
