Thanks for the advice from all on this. I noticed that the fresh oil was just as black immediately as the old oil oil,and this was before I started the generator up to check for. leaks after the oil change.
Air filter was pristine.
We have 3 basement air conditioners. That should be a 45 amp load. I will run it an hour as suggested by the Guru's. Have to pick a day when I am downwind from our friend who owns this ranch. I would hate to be evicted?
