I figured that was out of the question since I had cold piston slap with RL 5w20. The RL 0w20 is closer to the PUP cold visc that doesn't slap
I feel pretty bad for those of this forum who suffer through all these "oil related" problems. It's sad, considering how much one of these big super crew trucks cost, regardless of who makes them and the high levels of asinine problems consumers have to put up with.
I remember why domestics lost market share to Honda, Toyota, Nissan during the early 80's thru the 90's. Sadly, the coin has flipped in that so much of "domestic" vehicles are manufactured overseas/ across the borders, and the Asian cars are made here! What a dichotomy!
You should not have to go through this night mare after buying such a "high" end vehicle.
