This is maintained only and never saw any use. It's a Westinghouse WGen5300DFv generator that runs on both propane and gas. Gas = 5300 running watts with 6500 peak and propane - 4800 with 5800 peak. I get it out once a year to run and change oil and this year it shut off after a few minutes like it was the low oil cut-off. But here it is, in barely used condition with a hiccup and it can't be that serious.
