Can you use rottela t6 on a k20a3 (Honda)?

My friend says that rottela t6 is good and protects your motor. He says to stop using mobile 1 Because it doesn't protect your motor for too long. Btw he uses it on his Evo and no problems

T6 is very similar to Mobil 1. He doesn't know what he is talking about.

Rotella is no better than Mobil 1. All synthetic oils are good at protecting your engine.
