I changed the oil and filter in the Perkins  gen set this week.  The first time I have done so since owning the coach. We only ran it 20 hours in 18 months,  but i thought it would be cheap insurance. I noticed the oil that came out was rather thick.  I replaced it with diesel rated 15-40. It took 10 quarts. The Perkins has always been a little sluggish to fire up, but after the oil change, it is very noticeable that it starts much easier. I was surprised when walking behind the coach that I was putting out a blue cloud ..... I suspect the old oil was straight 40 , or maybe ' modified" with STP ?

Unless we are boon docking  , I wouldn't / couldn't used this gen set in it's current condition. But then again, I only need it when boon docking.

Any thoughts?
