Yeah its not the cheapest, but its worth it. And since we own the family business and sell gas, it helps cut costs for us a lot. Fuel consumption is also measured in Gallons Per Hour.
And to put it in perspective, this airplane here, my dad's 172:
Consumes roughly in between 7-9 GPH in a cruise.
This airplane here; owned by a customer, a North American T-28:
Consumes about 45 GPH in a cruise. Now THAT'S $$$ spent at the end of the day...
