Well thanks, Fourthbean. The only thing that's come from the testing so far is that my FE jumped around the time I started running Shell. But I don't know yet if that's due to the high detergents in V-Power, or from using Shell gas in general, or just coincidental from refining my driving technique. I guess time will tell, or at least it'll raise enough questions for someone else to run a more controlled test.
You're right on the mark about everyone sharing. I've learned so much from all
Just don't take it personally when the Leftover Bananas kick yer butt in the challenge, eh?
Seriously though, I seem to be leveling off around 34 to 35MPG. So unless I can figure out the next thing to do to bump my numbers...
