might be true this year charlie, wasnt so awful long ago there was a large consensus of engine builders swearing by slick 50 as well. as far as mobil 1 not being full synthetic id like to see where you got that info, besides royal purples own marketing.
That is what I have heard about Mobil 1...don't know if it's true...I don't think Mobil 1 is a bad oil at all...it's my second choice...because I did see where they ran a nascar engine for 250k at 8 or 9k rpm...i forget what the rpm's where, but i know it was high...but anyways when the drained the oil and took the engine apart...it should no wear what so ever.
But as for Royal Purple...I like it because I can tell a dif...In the way my ride runs now...smoother and quiker.
My first choice is Royal Purple
Second is Mobil 1

My first choice is Mobil 1 then RP (because RP can expensive lol) I really got to try it out though. Maybe after I use all my Mobil 1 oil I got for two oil changes then I'll try RP.
