Cost of propane vs gas generator.
I have read a lot about the pro/con of gas/propane generators. I have an almost new champion 75537i 3100 watt remote start inverter gas generator. I am in the process of purchasing a used FW that com...

Here are some personal experiences using both fuels in my Superior onveted bus, A Chevrolet pickup with cabover camper then flatbed and various 6.5NH and 2.5 KW Onan generators. Over 100,000 miles of driving in USA and Mexico over 20 years and thousands of generator hours
Again, these are personal observations.
- Propane runs cleaner. Pull spark plugs after 20,000 miles and the porcelain insulator is white. Zero coloration
- Oil stays crystal clear even for a year or more
- No running rich when cold. Ideal for starts and stops lasting a few minutes
- Had no problem starting engines in sub F zero weather with PROPANE.
- All engines leaked lube oil more, out of gaskets, even brand new engines
- Propane runs significantly hotter. I compensated with larger radiator but air-cooled generators may have an issue if enclosed
- I compensated for power loss with auto engines with 12:5 to 1 compression ratio, huge valve heads, and large overlap camshafts
- Generators seemed to lose 15% overall max Kw power potential
- Problem diagnostics with propane is a new learning curve
- Parts are never available locally
- I had been refused repeatedly in the USA to fuel onboard LPG tanks at dispenser outlets in California and in Mexico.
Again, these are personal observations.
