Thanks for the info. That's what I was more or less thinking, since both motors are GM V6's, but sometimes it can be a huge difference in the MPG's. Also, those with the 3400 motor, where is your tachometer when you go through those first few gears? I only ask, because my Alero hits about 3100 RPM, where as my dad's car, a Buick with a 3800 only hits about 2500, at the most. My cousin has a Pontiac Montana van with the 3400 motor, and it changes gears somewhere around 2500 RPM also. Any info about this?
