First off let me say I am missing about 10 receipts, all in-town, which would pull the average down since the road trip receipts are included.
That out of the way, for the 39 receipts I have, the green Z28 has averaged just over 22mpg, thats right, twenty two. The high is 30.4 (all interstate), low 16.2 (hot rodding it with a/c blasting). For the most part I don't beat on it, but frequently accelerate quickly (shift point <= 4k). As for the missing receipts, assuming the car averaged 20mpg for those 3000 miles (300 per fillup), which gets the odometer very close, it still has close to 21.6mpg. Not bad for a pushrod dinosaur. Only mods are a "lid" and Nitto drag radials. It has 96k miles. |

ususally 17-19 in my 5.7 TPI auto 3.42. I got 22 once with only freeway driving; pretty much cruise control @ 70-75 mph for 160 miles. Stock cam with exhaust and intake mods. Part throttle VE not tuned.
I've gotten O2 sensor codes, probably b/c the part throttle VE is off. |
