GU, I wasn't poking fun at all if it was taken that way. I, too, have noticed a definite increase in my gas mileage once I get far enough north and west to start using the lower octanes.

2 friends have Tacomas w/V-6 engines, auto trannys and neither gets above 14-15 mpg. Hard to believe,,,sorta.

The degree of my privacy is no business of yours.

What we've learned from history is that we haven't learned from it.
