Are you asking, “How much fuel does an RV generator use?”

Knowing how much fuel your generator for your RV uses is important so you can always be prepared.

Depending on the size of your RV generator, it will run 0.75 gallons of gas per hour more or less and if you’re using propane, it would use about 3.45 gallons of propane per hour.

What to Know About RV Generator Fuel Consumption

There are some factors that play into how much fuel the generator for your RV will use.

  • Smaller generators will use less fuel than larger ones
  • If you’re running multiple appliances at once, your generator will use more fuel
  • The warmer it is outside, the more fuel your generator will use

If you’re like me, you might have thought that you want to get the biggest generator you can haul around. However, if you do that and you don’t need all of that power, you’ll spend extra money on fuel because of the added size of the generator, even if you didn’t need the extra power.

Running lots of appliances can cause a much higher fuel consumption and if you try to do too much, your generator may shut off. If it does shut off, you just need to unplug some things and start it again with a lesser load.

Having a generator to keep you cool in the hot months can be really helpful but the hotter it is, the more fuel your generator will consume.
