And related to this, I have to wonder.... We get all worked up over what type of oil to use. Brand, weight, multi vs straight, etc. It's as bad as filter micron ratings and anchors. So I have to ask. Has anyone, at any time in their life, of the dozens and dozens of motors we have all owned over the years in various vehicles and machines, ever had one fail because they used incompatible oil?


Personally, I have never had a failure, or even heard of a failure that traces back to the wrong oil selection. And strictly my opinion - I think fretting over oil selection is one of the biggest non-issues in the world of engines. I think any reputable brand meeting an industry specification called for in your manual, or backwards compatible with your manual, is just fine. Then start the engine, and use it.
