Ohhh didn't know that ok thanks just learned something new.
Well, now necessarily 20W... just making a point. It shears down quicker than a mono-grade oil.

Gee, really? It doesn't do that in my BMW.
How quickly does it do that? I've only gone around 8,000 miles or so, maybe it will take longer or only happens in generators and stuff like that?
You know what I meant... otherwise everyone be running 0W-30,40,50 in everything. It has its trade-offs. Thinner isn't necessarily better. I also wouldn't compare an engine in a passenger vehicle to an OPE one, in terms of oil demands.
