With the Corona virus happening and in some cases just out riding around looking over the country for something to do a fair amount of the driving on this tank was 45MPH and a small amount at 40 MPH. I knew this was going to be a good tank and was hoping to break my previous best tank of 51.167 but the last couple times I drove it were slightly cooler/rainy days. This tank brought my overall average up from 47.081 to 47.231 MPG. I need to work on getting that average back as high as possible in preparation for next winter. This past winter I was able to maintain over a 47 MPG average. Last year 4 tanks from time of purchase-4/26 my average MPG was 45.180 MPG. This year 5 tanks 1/8-4/19 my average is 47.599 MPG. Some may remember I added an electronic throttle controller in Dec. 2019 that claimed it would help mileage. Worst tank since is 46.089 MPG and during the winter my MPG numbers from tank to tank were much more consistent. As the weather has warmed up this spring the numbers have increased accordingly Prior to adding the the controller I'd had 6 tanks with a lower MPG than 46.089. I think the controller is doing what they claim but with gas back down to $1.399 a gallon it's going to have a much longer return of $60 investment.
