I recently purchased a IH 384 diesel tractor that I need to change the oil in this weekend. After doing a little research on this website, I think that I want to use either Delo or Rotella in it. It seems like these are two of the most popular diesel motor oils and I don't think I've seen any negative comments about either one. Besides these are the two that Wally World mainly carries and they are the same price ($6.99 a gallon I believe). Just wondering if anyone had any comments on which is better? Also, what viscosity should I get? I asked up at my local Case-IH dealership and they said that they use 15W-40 viscosity on everything back in the shop. They said that I could also use 30 weight, but I think that I was leaning toward the 15W-40 because I know in gasoline engines, multi-weight oil are recommended over single weight oils by just about everyone. It would make since to me that the same holds true for a diesel engine. The 15W-40 weight would probably be pumped up to the engine faster on startup and would come up to 40 weight oil when the engine got up to full temp to protect it when it is hot. Am I making any sense? Thanks for any comments....

I work at a Perkins, Kubota, and Deutz (among many others)engine distributor and service company and we use Rotella 15W-40 in everything and I also use it in all my equipment at home (Dodge D-250 w/ Cummins diesel, MF 240, Cat D6-8U, and all my small engines). I also used Texaco Ursa Super Plus at a place I used to work and it was good too. The Delo oil has an excellent track record in over the road trucks from what I read in various trucking publications. I'd say pick one: you can't go wrong. I'm not sure the Texaco oil had all the latest diesel certs but it will work for most.
For what its worth!

Bradley B, In the final analisis it is your personal chioce. Both oils are basically the same and compatable. So use what you like.
Personally I don't like Rotella.....At ALL.
So I use Dello 15/40 in all my rigs. 966,Farmall M, F-150 w/ a 4.6 V8, 350 chevys, everything. Yes my F-150 has 240K miles and Suburban has 230K too.
Pruf is in the puddin for me.
Good luck with whatever you choose!
Later,
John A.

We've used the Rotella 15/40 for every diesel and gas engine we have for at least 10 years or more. Perkins 6-354 (boat), Ford Tractor with 172, AC D17 with 262, GM 6.5T and Ford Power Stroke--both in trucks. 6.5 has close to 200K on it and it still pegs the oil gauge. I believe the Rotella also has a few more API certifications too, but both oils are suitable for diesel engines in severe service.

Most, but not all, API certifications are backwards compatible.
