Is anyone using royal purple(10w30) on stock motors?(05-06) I dont see it hurting anything do you?

I am using 5w-30 and may switch to 10w-30 soon but I have a fully built motor.

You've got my vote for the best '05 mods to date. If there was a vote. That thing must be a beast now! I can almost hear it at idle.

I started to use Mobile 1 5-20, and i have an oil temp guage. Since the switch, i noticed the Mobile 1 running cooler than the Motorcraft stuff. At 6 bucks a quart, its not cheap, but seems to be cooling the engine and that is a plus. Is royal purple better?

I only average 4k miles per year, so I'd go w/ whatever is best. I only have the RP coating the 4.10's.
