1950 Allis Chalmers - 03/13/18 08:08 PM

Hello!

I just acquired an old WD tractor ("gasoline"/"distilate"/"tractor fuel"), and was wondering what BITOG would recommend running in place of the SAE 30 that the factory called for in the engine of this old tractor. I know most folks are split between 10W-30 and a 15W-40 but I was hoping to hear that a 5W or 0W would be advised, mainly because I have a few gallons laying around. What are your thoughts? This will never see field work, just a parade, fair, or tractor show here and there.

Thanks for your replies!

I used to have an old WD also. I think I used 10w30, but I would see no reason that a 0 or 5 w30 or 40 wouldn't be just fine. Especially for the type of use that it will see.

If it's in good shape, 30 or 10W-30.

My father had a slightly older Allis Chalmers. I don't know the model designation. Replaced by a '52 Ferguson TO-30 or 35.

I agree. I would not use a 5W30...just personal preference.

And why wouldn’t you use a 5W30? They are both 30 weights, the only thing likely measurably different may be the NOACK number and the viscosity at 100*F.

I say use it if you’ve got it. If you picked up any of the Delo XLE on clearance at WM, use that. smile

I would avoid any xW30, ILSAC, resource conserving, passenger car motor oils in general. SAE 30 is good, but 10w30 and 15w40 HDEO (diesel rated) oils are ideal (even in an old gasser). The reason being is these have a higher HTHS and are a little more in line with straight weight oils that would have been available back then. My 1952 Farmall Super C has 10w30 Rotella T conventional in it now, and if I were to work it hard in warm weather I would use 15w40.

No way I would use/recommend a (highly) unshear-stable 0/5W30 ILSAC oil in place of monograde 30 engine oil , in any applications whether new or old equipments.

If it's just being used in parades I don't see any issue with a 5w30, just monitor the oil level closely in-case it increases consumption or leaks.

I have been using 5w-40 in my 1950 Ford 8N for the past 15+ years. Philip.
