I have been a reader here for sometime and now that I have run the first tank in our new Nox FWD V-6 I am happy to report..... Tank #1 mixed driving with four grown folks has yielded 19.8 hand calculated. The whizbang on the dash said 20.2 so it was in the ballpark. We are running tank #2 now and have the tires pumped to the 44LB max pressure, they were at 32 LB for a better ride. More after next fill up.
