I've read 15w40 rotella was the best, I was also told by a mechanic that rotella was the best oil to use if your going to do the oil changes yourself. Someone correct me if I'm wrong!

Wasn't sure if Wal-Mart was a good choice I'll make sure to get it there. What filter do you use or recommend?

 

[Stew Pudasoe]

Oil is oil ha... But read on which filter is good. Everyone's opinions are different and this is where the pissing contests come in at haha google best oil filter for dodge cummins!

Do you really run your Truck 2 Quarts low all the time?

They need 3 gal/12 Quarts.

Walmart is the cheapest for rotella t6. I usually will buy ot 2 weeks ahead as they never have enough. Rotella is rotella no matter where you buy it
