Ok im going to try this auto rx stuff when i get paid this week. How many times should I do it? Its pretty expensive stuff.
Also from that long paragraph of really smart oil terminology i kinda got the impression that I should go back to the 10w30? Not trying to sound like a smart *** , but i just dont understand what all that meant.
Also one thing i forgot to add and i dont know how i forgot this. But one thing that has come back is the piston slap as ford calls it. I used to get it when I first bought the truck. Was told to goto m1 full syn 10w30 and the mc filter. It went away. Switched to the 5w30, didn't really ever here it. Now with the 5w20 i can hear it all the time and even after its warmed up i still hear it.
