The most i have gotton it 341
31 mpg

 

467 miles '02 Impala w/3.8L got 31.5 mpg , still had 1.2 gals in the tank. I have records going back to 1980 on every drop of gas that went into all my cars. (a few from the early 70 also)

 

548 miles in my HHR.

 

sorry i should have stated in you HHR

 

481 miles in mine

 

I did a 492 but I have only 1725 miles on it so far so it should go 500 or better when it hits the 10,000 mile range.

 

502 miles here using mid grade while traveling

 

I dont drive it below 1/8 tank simply because the fuel pump is submerged in the fuel, and relies on the fuel itself to keep cool.

But...that said, so far, the most the DIC "says" I can go after a fill up, is 480 miles.

 

Damn mine hasnt said 480 miles in a long time it changes when im on the highway though, i dont know how many miles i have got on one tank but i did go from cincinnati to toledo ohio, and back on one tank of gas.

 

This summer on a trip.....523.6 miles.
