15w-40 Engine oil

Simply put.. Rotella Conventional Oil or Caseih No.1 in 1950's gas and diesel engines. Price locally is similar this weekend.

Any 30 weight high detergent oil works well for a 1950s vintage tractor. I have been vigilant with my oil changes on my case 411For five years now. I have a very clean motor .very little residual sludge to be found in my motor.CM

I use Case 15W40 in all my machinery. Would never consider anything else. And as you said it's competitively priced.

That looks like it has not been warmed up good enough to boil moisture out.
