Find a 15W-40 that says for mixed fleets and your good to go.Thanks for that memo, I personally did not know that and I would have dumped in 15w40
That top compression ring being stuck in the ring groove is common on high hour engines. I cant say I buy the oil type causing that issue, its more of a combination of dirt infiltration in the airbox....even more so the major cause is incorrect injector timing or insufficient atomization causing excessive heat.I rebuilt a few Detroit Diesel engines over the years. The ones that ran 15w40
the top compression ring were always stuck in the ring grooves. A coworker
with lots of Detroit Diesel experience told me that 15w40 was the reason for that.
Detroit Diesel called for low detergent oil for their two strokes.

On the contrary, this topic alone should have its own thread. It can be like a giant pillow fight! I mean, who wouldn't want to smack Bluox a few times! LOLI believe I've come to the conclusion to not bring up this topic anymore as it always gets to be quite a topic of discussion
I would suspect the oil was in the airbox and when the top rings went below the ports in the cylinderSo how did the oil get to the fire ring?

So its all YOUR fault! LOL-I was the one who posted pages from detroit manual showing the use of 15x40.
If you join the Barrington engine club they have that info, you know the DD experts that recommend change oil every 150 hours and the filter at 450 hours?Oil threads-I was the one who posted pages from detroit manual showing the use of 15x40.
What oil should I run in a briggs?
I have a copy of the 1997 Detroit Diesel Lubricating oil, Fuel, And Filters manual if anyone really wants to see pages from that!So its all YOUR fault! LOL

The 30 or 40 wt. oil that doesn't exist any more.
Ya gotta love these experts these guys come up with but I guess these may be somewhat closer than Willes used Grayhound bus salesman in Texas selling wore out buses to Mexico 25 years ago.
