Oil & Fuel Engine Oil

[wushaw]

You are absoutely correct on the lower viscosity & fuel mileage thing.
I don't why that guy said that, here is what their web site says.
- ROTELLA Products

I have used Rotella T in my diesel powered boat for years with great results. The marine environment is very harsh and the engine performed well. As a result of this experience I will be using Rotella T in my tractor. Its a great product.

I have a Kubota 2350, and was wondering about engine oil, I use Rotella 15w-40 in my pickup truck, and was thinking I could use the same oil in my tractor. What ya think?

Rotella 15w-40 is what most people around here use for their diesel trucks and tractors, I use Rotella 5W-40 in my tractor because I only change the oil once a year and the 5W seems to start better in cold weather. In my Ford truck I use the recomended 5W-20, with the Ford V10 overhead cams the thinner oil gets up there faster. Both Rotella 5W-40 and 15W-40 are rated for gasoline and diesel engines.

^^ That's funny right there. (My own Mrs. has trouble with cold start-ups.)

Rotella is good 'nuff stuff.

I neglected to mention that synthetic oil is not recommended until the appropriate break-in period has been reached.

Well I'll speak up. The owners manual recomends 10w-30 and thats what I stick with in my BX2350. I am using Kubota brand, but anything would work as long as its meant for diesel engines. Its kind of hard to find in other brands so thats why I stick with the Kubota stuff. The long standing tradition has always been 15w-40 for diesels, but hey Kubota makes the tractor so I stick with what they recomend.

David, I agree that it's always a good idea to go with what the manufacturer recommends. But sometimes, the manufacturer (in this case Kubota) may be a bit behind in updating their English language manuals. I know my Kubotas also recommended 10W-30, CC/CD, oil. CC/CD ratings are a bit obsolete. So every dealer I talked to, as well as one Kubota factory rep, said 15W-40 was good, in Texas at least. I'd say 10W-30 CC/CD is the minimum you should use.

Shell does also produce a Rotella 10w-30 . I'm thinking of using this on my next change from Kubota 10w-30 as opposed to using the Rotella 15w-40.

I wasn't aware the Rotella 10W-30 is qualified as a diesel engine lubricant.

I use Mobil 1 Turbo Diesel 5W-40 100% synthetic oil in my B7610. IMO I wouldn't use anything but a 100% synthetic oil, but to each his own.

I used to think that I would use all synthetic too, but this weekend I went looking for my usual Rotella T 5W-40 for my annual oil change. But all the places I went either quit selling it or was sold out. There was no synthetic 5w-40s available so I ended up with Rotell 15W-40. So instead of spending $30 for enough oil for one oil change I spent $24 for enough oil for two changes. I don't know what happened to the supply of the synthetic oils? The first place I went had Mystik JT-8 synthetic blend 15w-40 but I kept looking for full synthetic.
