I actually did a search on this issue and need a more definitive answer ?
With Premium costing an average of 40 cents a gallon over regular
Everyone is stating that its a waste of money to get a lousy 10Hp
thats only available during WOT.
But the confusing part is ?
If Premium Fuel forces the Computer to advance the timing,
Doesnt that net better MPG ? Offsetting the extra cost of fuel
So why run Regular at all, if not only your loose HP
but your MPG actually goes down
Not to mention, Higher Octane engines run much cleaner
saving your valves and pistons from carbon overload.
Plus I actually read somewhere that WOT on regular
is not cool in general as detination is maybe not actually heard
but its not healthy for the engines long term longevity
Again Premium is about 40 cents a gallon extra
which is about an extra $5 a tank.
Solution ? when ordering your favorite fast food fix
Substitute the $2 soda for a cup of water with ice
and skip the $3 Brownie Fudge Delight
You'll loose weight too
and go even Faster ~~
