Hi JenGo, that was from the main tank which holds about 3.2 US Gallons. The advertised MPG for the Warrior is 39MPG which yields max ~125 miles from the main tank (3.2 x 39). The Arizona desert roads mentioned at that time were flat and straight for many miles, which enhances mileage as long as the throttle is kept generally steady. I usually ran those roads somewhere between 60 and 80 mph depending on conditions. After being transferred to Oregon the roads are a bit more steep and mileage is down a small amount but not as bad as I expected. I can easily get over 100 miles from the main tank (3.2G) but its more fun to play!
