No — do not run E85 (85% ethanol, 15% gasoline) in any standard portable or standby generator. The fuel system components, carburetor jet sizes, and engine tuning are not designed for ethanol concentrations above 10% (E10), and using E85 will cause rapid, expensive damage. What E85 Does to Generator Fuel […]
The cost to run a generator varies dramatically by fuel type, and the “cheapest” fuel depends on your local utility rates, how often you run the generator, and at what load. Here’s the data to make an accurate comparison. Cost per kWh by Fuel Type (2025 U.S. Average Prices) Fuel
Gasoline generators burn fuel faster than most owners expect for three reasons: gasoline has lower energy density than diesel, portable generators run at constant 3,600 RPM regardless of load, and most owners overestimate how much of the fuel actually reaches the tank. Reason 1: Constant RPM = Constant Fuel Baseline
Maybe. Whether you need a meter upgrade depends on your current meter capacity, your total household gas load, and the generator size you’re installing. Getting this wrong means the generator starves for fuel under load — or your furnace and water heater stop working when the generator is running. How
Yes, a propane generator can run on a standard 20 lb BBQ tank — but runtime will be dramatically shorter than most people expect, and there’s a physical limit on how much power you can draw from a single tank in cold weather. Runtime from a 20 lb BBQ Tank
