Hi Jerry,
That sounds like a simple approach. I have a bunch of Walmart 5W-30.., that should be fine no? It already has a pan full of the same 5W-30 from about 2 years ago and I haven't ran it more than 2 minutes in those 2 years. Can I use the oil in it or would you recommend changing it again?
Any insight into the oily sludge in the water jacket? Thanks,
James
