For those of you know the Clark tank holds 2.8 gallons. I have never run it empty, but the last 3 tanks I rode until I had to switch to reserve. Took 2 gallons, and I went 185 miles.
Also when I did the oil change I switch to Amsoil and had used the Shell reg gas. I average 91 mpg on it since I switched. Don't know if it was the oil or the Shell gas or a combination of the two. I had used Loves gas up till then. I am running this tank on Loves gas to see if the mileage changes. The 81 mpg was what I had average before the oil change.
I might add this is in the southwest part of Arizona.
The TW I have in Illinois I also only got around 81 to 83 mpg.
