From my time in aviation maintenance, I remember it was acceptable, as per the manufacturer, to run different viscosity lube oil for winter/summer.The manual in this one says 0-20W oil or you'll void the warranty. It's a tough gamble. Void warranty to maybe make the engine last longer??? My concern with light oils is they design the clearances to be tighter in the engine, which means less clearances! But as the engines are designed for lighter oil, they may not last with thicker oil.
My current plan is to run 0W-20 until the warranty is up Then switch to 5E-20 or maybe 5W-30.
The biggest thing is to have shorter change intervals. Currently I've chosen 4000 miles. Since filters and oil are cheap, I might drop to 3000 miles...
Any Tribologists in the house?
I've also seen that for marine engines.
