101Volts · 11-26-2013, 05:20 PM

For most of the trip legs out of 11.7 miles today, I was getting rather low MPGs partially due to high tire pressure (About 55) and then I stopped at the gas station and set the tires to 46 all around; Then, For the trip home I got the highest MPG figure all day and I did feel more confident about accelerating at higher engine loads; It also helps that I can accelerate at all since I had trouble going up hills earlier! However, This isn't an A-B-A-B test on the same leg of road. But, I thought I'd share the thought.
