so many posts since I checked this last
The thing with the O/D. the reason why I leave it off is because when driving a BMW it shows you on the dash how much gas you are using and it appears that the car burns more at lower RPM (trying to accelerate in stop and go traffic). The reason for that would be that if you are in a higher gear and try to step on the car the gas is gonna go in the cylinders but it will not burn all the way and you still will be getting nowhere. I had a little mazda 323 back in the day and I put one of those Econ gages in it and that showed the same results as the BMW thing does.
Also with the O/D off I am constantly in a good RPM range to get response out of the car when I need it, meaning I save time from down-shifting and the tranny searching for a gear.
So far on this tank I have gone 60 miles and the little arrow just started going down. I think I could do 100 miles before I go down a 1/4 of the tank.
Interesting fact is that I have always gotten way good mileage on the freeway even at high speeds (80+ mph). I mean even when the car had bigger problems. right now i think its mostly the cold driving in the mornings and not letting the car warm up enough. there are times that the temp barely goes up to the middle before I pull into the school parking lot. I also am always late so I drive kinda hard quite often. I feel blessed to have a VQ under the hood because if it was some other car and different engine it would have been way beat up by now with the way I drive.
