    I was just wondering what oil and trans fluid everyone with the cummins trucks uses. I noticed a product from Valvoline called premium blue that was supposed to be produced w/ the help of cummins.Anyone use it? Also what about amsoil for engine/trans? Just wondering.

    I have used Rotella Synthetic 5w40 since the 20K mark. If Amsoil sold in a store here I would definitely buy it though. I have Amsoil air filters though & a couple other odd & end things. I just don't have enough room to store oil. You might check on Cumminsforum. There are a couple vendors that are running free Amsoil membersips right now w/ a purchase.

    Valvoline Premium Blue 2000 is synthetic blend 15w-40 that was developed for Cummins by Valvoline. It used to be sold in a white bottle wih a blue Cummins label. After a few years on the market Valvoline started selling it with their label. I used to run it in L10 & M11 applicatons and I got 25,000 mile change intervals out of it. A very good oil. My boss switched to Chevron Delo 400 15w-40 dino oil cuz of a pushy salesman and I get 25,000+ mile change intervals out of it too and it's cheaper than the Premium Blue. Also a very good oil.
    Trans required ATF+4, which if I'm not mistaken is synthetic ATF+3 and it's available at WalMart.

    Amsoil everywhere except engine oil where I use a blend of Delo and Amsoil. I like the moly and boron and sealing of the Delo and I like the calcium and the synthetic basestock of the Amsoil.

    I have run Rotella-T in my 91 and it has 480k on it. Uses no oil at all. In the trans (727) I use Type- F fluid.
    I have use Amsoil and I don't care for their "pyramid scam" style of marketing.

    I went with the shell rotella synthetic. 17 bucks a gallon I figured was pretty good for full syntetic. Amsoil was 26 bucks and regular shell rotella was 10. I'll see if I notice any change in mpg or cold weather starts.

    My truck just turned 11000, so i've only changed the oil once, went with dino rotella T 15w40. Bought a case of six gallons at Costco for just just under $50. Comes out to be $8.33 / gallon. Get my filters directly from Cummins instead of paying a dodge dealer $38 a piece. Haven't noticed any cold starting problems until we got to highs that were less than 10 degrees F. Had to crank maybe 5 or 6 times before it would fire and then it was a little rough for a second. Of course that was also in the parking lot at work where I had no access to plug the block heater in.

    I do not think Premium Blue 2000 is being offered any more. Valvoline released Premium Blue Extreme, a Group III synthetic 5w40, and I think this replaced the PB 2000.

    To the OP, since you live in a colder climate I might recommend a 5w40 synthetic. The Shell Rotella Synthetic 5w40, Valvoline PB Extreme 5w40, Delo 5w40. The Mobil Delvac 1 is also a great 5w40 oil but it is a Group IV oil so it cost a little more than the Group III's mentioned.

    As far as a dino oil, any of the big name brand oils (Mobil, Pennzoil, Valvoline, Shell, Chevron, ect....) will be a good oil and provide very good protection at a regular oil chance interval.
