I just did my first oil change at 2362 miles. I used Rotella T6 5w-40. I asked the dealer lol what weight oil I should use and he said 5-40. The main reason I changed it early was because no one could tell me what was in it. Weight or brand. I also changed it because I have an extended trip planned later this month (towing) and didn’t want to have to change it while traveling.

I am trying Triax Fleet Supreme. Check them out online. They have the CK-4 rating & a grocery list of other specs. They get great ratings & sound like they have been around for awhile supplying the military & larger fleets, but are now selling to the public. I am going to take a sample from my next oil change to see how it "really" performs. I can tell that the engine is quieter with this oil but I can't say for sure if I am getting better mileage from it or not, because I also installed a Banks system about the same time. I have gained 1-1.5 mpg but again I can't say for sure what it is from.

Sorry for the off topic question, but @68PowerWagon what Banks system did you install?
I can't remember if I responded to you via pm or not. I bought the Banks CAI, intake horn, & boost tubes. It does get up & move better & I gained my mpg back that I lost installing bigger tires. Is it worth all the money I paid for it? Probably not, but their stuff is of high quality. Additional bonus is I don' have to worry about the grid heater clogging up or the bolt falling off into cylinder #6.

DO NOT use Rotella T4 in your Cummins! Cummins changed from solid valve lifters to hydraulic and using T4 15-40 will cause engine clatter with hydraulic lifters. I have the solid lifters in my 2011 and have used both T4 and T6, and the oil stays cleaner/clearer than my gas powered car's oil. I would recommend Rotella T6 5-40 for your new Cummins.
