Question 1

Can a tri fuel generator run on natural gas and gasoline at the same time?

Accepted Answer

No. The engine burns one fuel at a time. The fuel selector valve routes either gasoline, propane, or natural gas to the carburetor, but never a mixture. Running two fuels simultaneously can cause flooding, backfiring, and engine damage.

Question 2

How much wattage do I lose when switching from gasoline to natural gas?

Accepted Answer

Expect a 10–19% drop, depending on the model. DuroMax's XP13000HXT drops from 10,500 running watts on gasoline to 8,500 on natural gas—a 19% reduction. Always size your transfer switch and essential loads against the natural gas rating.

Question 3

Do I need a professional to hook up the natural gas line?

Accepted Answer

Yes. Connecting a generator to your home's gas main involves plumbing, pressure regulation, and often a permit. A licensed installer should handle the permanent connection. The quick-connect hose itself is user-friendly once the line is properly installed.

Question 4

Is a tri fuel inverter generator safe for sensitive electronics?

Accepted Answer

Inverter models with THD under 5% are generally safe for laptops, TVs, and medical devices. Conventional generators produce "dirty" power with higher THD and can damage sensitive electronics over time. Check the manufacturer's THD specification before plugging in expensive gear.

Question 5

Can I convert my existing gasoline generator to tri fuel with a kit?

Accepted Answer

Yes, conversion kits exist and can cost under $100. But installation difficulty varies, and a poorly installed kit can be a fire hazard and void your warranty. If you're not comfortable working on fuel systems, buy a factory tri-fuel unit instead.
