Diesel Engine oil..Preference?

[Banjo]

What is everyone's preference on their oil they use in their tractors? I've been using Shell Rotella 15W/40 for years but recently heard a mechanic say he didn't like it. What say you guys.....

Rotella 10/40

Our tractors all get Walmart 15W40, which I hear is Shell Rotella repackaged. Oil gets changed every 100 hours.

In my truck that I just built a new engine for, I'm going to go with Lucas diesel engine oil.. a bit pricier, but a friend of mine swears by it so I'll give it a shot.

Been using 5W40 synthetic in diesels that must run in winter. Kubota starts good in unheated shed without being plugged in down to 0. Last year I used Rotella synthetic. This year the oil is changed with Cenex Maxtron 5W40.

Rotella synthetic. Truck and tractors

 

[Chainsaw Driver]

Rotella 15W/40 exclusively. I won't run anything else. I've had excellent success with this oil for nearly 20 years. "If it's not broke, don't fix it."

Walmart 15W-40 in the truck and loader tractor, Walmart straight 30 in the other.

Did regular oil testing on truck when first started using Walmart oil (switched from Rotella - too expensive) and test results from two credible sources gave Walmart oil a big thumbs up even after 5000-6000 miles.

Using this for years and have over 5000 hours on a tractor with still a tight engine.

I only have one tractor, a John Deere, so I'm not maintaining a fleet but I use John Deere brand. I've never heard a bad thing about Rotella though. I wouldn't use Wal-Mart anything if it was free.

10w OR 15w is too thick for SD winters, or is it just that you don't plug in?

I use mobil delvac 15/40 in our tractor and chevron delo 400 in my cummins.

 

[Limomike]

Still using Rotella 15-40 in mine

Does the old 15w/40 rotella still have foaming issues? Just curious because that's why I don't run it.

 

[Mat Man]

We have used rotella for years in trucks & tractors with no issues .
Never seen it foam?

 

[Calhoun Farm]

I first heard about it with 6.0 guys and ford not warranting injector issues because when the oil got hot it was foaming.

No it doesn't, we use it in some things and it's fine.

Big barrel of Case Akcela oil. 30 for the old tractors, and 15w-40 for the new stuff.

Rotella 15-40 in mt Dodge Cummins and 10-40 Penzoil in my Kubota MX5000 no problems.

To oil or not to oil, that is the question.
In my dad's tractor (Ford) he uses Rotella 15/40. (some foaming)
In my 7.3 I use Motorcraft 15/40
In my tractor (Massey Ferguson) I will be using either Supertech, Citgo or ?? Not sure as this will be the first oil change on this used tractor for me.
