Posted on NE3G so I figure I would ask everyone here. With the rising fuel costs is just doesn't seem like it would pay to get rid of my Saturn.
For me, rough average on them would be:
Saturn: 32mpg mixed
Silverado (4.8 Vortec): 16mpg-18mpg
LS1: 20mph-21mph
LT1: Odometer doesnt work so I don't know
L98: Horrible since the tq converter wasn't locking up when it was on the road.

Bike (1632cc Victory): 42mpg-44mpg
Is it bad when I use the RPO code for the motor to describe what Trans AM I'm talking about.
