Thats an interesting method, I will try that next time. Well other than emergency fill ups like today, I usually go to BP. I live in north eastern Ohio and to be honest have not looked for a difference between gasoline quality. Just out of curiosity do you think I did any damage to Pearl today by running out of gas? The engine was most definately warmed up if that makes a difference. I sure hope not. After tearing her insides all out to do the sound proofing I'm feeling like I abuse her. . .
In North Alabama, I found BP, Conoco, Citgo and Texaco had less energy per gallon. But I'm pretty sure the quality of gasoline, as far as energy content, needs to be tested in each region. I suspect your gasoline comes mostly from Canada. No. Let me suggest get the interior finished and then plan on a gasoline study. You want the vehicle weight to be pretty much the same so completing the interior helps fix the weight. A gasoline study will be a lot easier if you have a hill, say 500 ft or higher with at least a mile or two run. One of the easiest way to see the difference in gasolines is to climb the same hill at say 55 mph and measure the fuel burned to climb the hill: A divided, four lane highway up a pretty good grade is a great test route. A quick map scan suggest I-480 between I-77 and I-271 might be a good candidate. It looks to be about a 2-3 mile run with a 100 M change in altitude. Sad to say, I couldn't find many larger grades in your area. Bob Wilson
That's funny. 61.8 seems to be the sweet spot of what has been maintainable for me via the trip computer. Last time I filled up that is where I was at too with it normally varying from 61.6 to 62.0. Actual MPG turned out to be 58.23 however. The trip computer always seems to over estimate by about 3mpg.
