I have a 2011 1500 4.7l. my 8000 miles were almost up so i dropped it off @ pepboys and had them put royal purple oil and a royal purple filter on it. They called me 10 mins later and said that they dont have a royal purple filter with a "valve" and that is what the computer says my truck needs. they said they were going to use a K & N oil filter because it has a valve. I am totally cool with that filter but was wondering what the hell they were talking about. I never got the chance to talk in detail about it with them, they just said they didnt want to screw up my warranty by putting the royal purple filter on. The guys up there are reliable and i have been taking my vehicles to them for years now. but sometimes i change the oil my self and i guess i would have never known about this so called valve!
