Fuel Usage in Onan 7.5 Generator
Just a little bit of information that could be helpful. Recently I was at a show at the NRG Center in Houston, TX. We ran the generator for 126 hours in close to 100 degree heat. Fueled up in Brookshire, drove to NRG, then returned to Brookshire to fill up the tank just to determine how much fuel was used. We ran both AC's during the day, only one after 9PM, and we used a total of 60 gallons of fuel. From Brookshire to NRG is approximately 82 miles round trip. I figure that is less than 1/2 gallon an hour.
