How far on a tank
My best was 624 miles, and put in 10.49 gals, which is the most I have ever put in the tank at fillup. I have had many tanks last between 500 and 550 miles, but I tend to chicken out when the last pip starts flashing. Most of the time, I fill up when it is convenient, and the guage is down to the last 3 pips or thereabouts. So far, I haven't run out (knocking on wood as I write!) I never got the TSB done on my filler/tank, etc. as the tech at my dealership said it wasn't fixing the problem on the cars he had done it on. I have kept all the gas receipts, and figured the lifetime mileage at 63,000 miles to be 54.2 mpg. For the last 28k, the average has gone up to 56.7mpg, but I have been really watching my freeway speeds, mostly keeping to 55-60mph, except in the carpool lanes. With the tank rated at 11.9 gallons, that should take me about 674 miles, but no way am I going to risk it! Regardless, I have to chuckle to myself everytime someone in a Hummer or other huge vehicle roars past me, only to wait at the next signal for me to catch up.
