agreed.....it's just a mental thing more than anything.....
i have the same problem with one of my snowmobiles - it's dedicated to run on premium only, and with premium here at $3.70, guess what - it sits. And I want to drive this car, a lot.
I'd much rather give up 50 hp and run el cheapo 87 vs cringing every time i gotta fill the thing up (not that i don't cringe already!)
