I just did an oil and filter change in my Generac 5.6kw gen set. I used Amsol 5-30 synthetic oil for the job..... Everything went well and I was a happy camper....The gen set only has 450 hrs on it and I just wanted it to last as long as it could. I am at the local RV dealer talking about a lube job and oil change on the MH and mentioned that I had just changed the oil on my Gen set..(With Synthetic oil)......The Tech told me that they have had a lot of trouble with Synthetic in Gen sets.....Evidently the oil pressure sensor does not like that thin oil (when the engine gets hot) and will stop the gen set due to lack of oil pressure...???? Has anyone heard of this or is this guy just "Way Out There" ????
