Getting ready to go out the door on lunch break and buy oil for oil change on my '01 5.2(318). Truck is at home so can't look and need to know WHAT GRADE IS SPEC'D? 10-30? Help-o rapidimonte.

 

I don't know if it is "spec" or not, but I have always used 10W 30 Mobil 1. I have always used Fram filters also, but after looking at a filter test I had posted up on here a couple days ago I would get a Purolator, Motorcraft, or Wix filter....

 

I used to never run lighter than 10w40 but then moved to 20w50. When I switched to synthetic, I started using 5w50. I'm happy with it.

 

thanks for the answers. my friend who owns the parts store knew it was 10-30 so wasn't the problem i thought it was gonna be. sold me Valvoline dino, went with a Wix filter but the longer "ford style", not the short one spec'd for dodge. Cussed the whole time doing the change cuz whatever tech they had working at the dealer I bought this truck from decided both the drain and the filter would NEVER come loose if he was gonna have a say about it, lol. It's all good now.
