Message Houston, you should not lump Royal Purple with Mobil 1, Shell/Pennzoil/Rotella, Amsoil.

I cannot recite or articulate the explanation, but Royal Purple elicited first an eye-roll, and then a lecture in response to my literal words"why Shell over Mobil 1, Amsoil, royal purple, etc?". The others were basically viewed as true competitors. I have always used Mobil 1 at Nissan's recommended weight on every Nissan I have owned. Engine lubrication has been the least of my issues, doesn't even register TBH.

HOWEVER based on my talk with this guy should I get a better deal on Shell oil, I see no reason not to switch. The differences are 100% negligible for 99.9999% of applications
