My MIL had generac standby generator installed by her oil company in 2015. Contract included a 6 month oil change and a 1 year maintenance service. I was working on her circuit panel and had to turn off the generator. After opening the cabinet, I noticed oil dripping everywhere. The oil filler cap was not tightened securely and was at the bottom of the cabinet. There was no oil in the sump (per dip stick reading). Called the oil company to find out when last service was done and was told no service was ever completed. So the generator was running with no or low oil since the 2015 install (or whenever the cap fell off). Oil company cleaned things up and added oil. They said everything was 'fine' and nothing to worry about.

I find it hard to believe that no damage could have occurred to a gas engine potentially powering through its exercises/storms for over two years without oil.

Should I be concerned with premature wear/early failure? What options do I have at this point?

many thanks -jd

If it never shut down on a LOP fault, I don't see where you would have an argument on possible damage. Design is to shut down before any potential damage. Sure it blew out most of the oil, but not low enough to trigger a shut down.

The dipstick does not go to the bottom. It could have just been a fraction lower than the end of the dipstick and it could still be fine. Or it could have been running on dregs of frothy oil and tearing up the inside of the engine. The only way to have known for sure would be to drain it and measure or see how much it took to refill. But that opportunity is gone now. All you can do is run it and see if it smokes or uses oil too rapidly. I have seen this happen a number of times and never seen one damaged by it but it sure makes a mess.

Many thanks for the quick replies. When I turned off the main breaker, the unit kicked on and ran until I turn the main breaker back on....hence my trip out to the generator. If all I need to worry about is a messy cabinet, then I'll sleep a lot better. thanks again.
