0W40

[FATTONY]

No issue that I know of UNLESS they are leaking like mine were... I learn about all the issues from all of you on here Thanks to all of you... AND I from what I learn on/from the truck itself... When I took it in to have them replaced (under my warr.) it came to $296.82...

i work at a dodge dealer and have had a very hard time getting all weights of M1. so talking to many of my suppliers they tell me mobil 1 and valveoline were in some sort of lawsuit. valvoline was stating that there synthetic oil was the best on the market. well the mobil 1 guys stood tall and say no way valveoline. so the out come in court was valvoline was better and proved it in the lawsuit. so mobile went back to the drawing board to change there mixs in the mobile 1 oil. this is why its tough to find M1 as they are changeing the mix of M1. this is why mobile 1 has put out a discount for its customers. just go to the mobil 1 website and get the rebate.

Yea, but now keep an eye out, Chrysler just signed a contract with shell and Chrylser will quit shipping M1, instead it is a Penzoil synthetic We just got our first shipment of that crap here along with Quaker State I wouldn't put the crap in my lawnmower

So what's wrong with the Shell Full Synthetic 5W40? I've put it in my truck the last two oil changes without a problem. It has more certifications than the M1. I've always heard that it is some very good oil.
