Depending on the engine how and where you run can effect fuel economy. The .25 engine according to HPI is 2.5 horse power @ 29,000 RPM .Even if the numbers are not 100% correct your getting over 2 horses out of your engine. If you get 12 to 15 minutes per tank and your tank is 160 cc. There are 2000 cc in 2 liters of fuel. That is 12 full tanks. Roughly 156 minutes or 2.6 hours for 2 liters of fuel at 13 minute run times.. You may get a bit more if you go easy on the throttle or less if your a lead finger. If it is running good then keep on having fun. Some engine are hard on fuel.

I have heard that the OFNA engines were a bit on the thirsty side. That is one brand I haven' played with yet. I get pretty good economy with my O.S. and my Traxxas engines do pretty good. If your pushing around a few pounds of truck it's going to eat some fuel.
