I’m with the posters that say go with the factory recommendation. I have used a 5W30 in a 5W20 engine and it didn’t cause issues, but if you cannot find an empirical reason to switch why do so? (I switched back after one OCI)
Exactly what i am talking about. Shooting off your mouth when you dont even know my background. Have you ever been hunted by terrorists I have. Have you visited countries now forbidden to US citizens. I have. Have you lived outside the Continental US multiple times. I have. You are typical of...

Do you all think we are someday going to see more application specific specs in the US like in Europe that will really kill universal backward compatibility (e.g. Porsche, MB, VW, Renault) or will that not be accepted by the American consumer? I kind of like the idea of lubrication designed with...
...allow for backward compatibility. Given that certain engines thrive on things like zinc or moly, can new specs that significantly alter an oil’s formulation, really find ways to cover the bases for older designs? If the changes are minor, then I can understand, but it seems like each new spec...
