It costs about 5.00 per hour to run my Generac propane generator. No complaints other than that.

$5.00 an hour! OMG. My diesel costs $1.50 an hour.

My propane Gen will run for about 8 hours on a 20lb tank and at $22-26 a refill, this is the most expensive way to run it @ 6kw output.

I could get a 500lb tank and buy in bulk for cheaper, but it still won't be as efficient as diesel.

I do like that the exhaust is not noticeable at all and it runs "not too loud" as I like to keep it near the house so it doesn't wonder away on me.

Yes propane doesn't have near as much energy per gallon as diesel. To live on the power its not worth it, as a standby generator they are dependable, don't cost a fortune and work great. Right now I run mine to heat water, Wash and dry clothes.
Use a small gasoline one for everything else.

Mine is a 16kw generac with a 200amp transfer switch. 16kw-22kw use the same 999 cc twin cyl engine. They are really strong machines.
At 5.00 per hour I run the electric water heater, split unit any and everything.

The 16kW Generac will certainly use a lot of fuel at full load, $5/hr no surprise and if it's like my 15kW, will use minimum half of that at no load. So you really don't want to oversize your generator once you get over 5kW.

Another nice thing about propane, more time between oil changes, your used oil will come out looking almost like new. Plugs don't foul either compared to gasoline.

My generator must have a defective plug, I've had to pull it twice to clean it up and now it wont start... and finding a generator spark plug on island isn't super easy...

I think I'm going to buy a 5kw inverter generator that runs based on load (it will idle down if you use less) costs a bit more but I think it will be more along the lines of what I need (which is probably far less than 5k normally).

plus it runs considerably quieter.

Usually if you have a plug issue with a propane generator it is because the gas regulator is the wrong size or defective.

Yeah those inverters are nice, my brother has a royobi 2300 for work and says it is better than the Honda 2000i he has used both and the Royobi is half price,

They are great machines on our normal Wapa circumstances

So maybe make sure the vacuum line from the manifold to the regulator is clear and connected.

My Generac came new with an extra set of plugs. Always good to have a spare set. I love my little sand blaster spark plug cleaner, makes plugs like new too. Some say they are not to be trusted due to risk of getting grit in engine. I just blow the plugs out like crazy, no remaining grit whatsoever. The plug gap on propane is usually a little smaller than would be with gasoline for same engine.

I'll try cleaning up the plug and making sure the gap is smaller than I'm used to, but at this point I'm going to use it as a backup generator or sell it.

the inverter 5k gen (Briggs and Stratton) runs for 14 hours on a 5 gal tank supposedly... 14 hours for ~$15 and it's pretty compact so I can put it in my truck etc.. I like those numbers.
