Oil for antique tractors?

[aking]

I have two Case VACs a for 8N and a Minn. Mo. U302. I've been running Valvoline 10w40 in them. I was wondering if this oil is a good choice in these oil tractors. I'm considering switching over to Rotella after I use up the 10w40 I have. Let me know what you guys think
Thanks

I would go with an HDEO in either a straight 30 or a 15w-40

Use HDEO or antique tractor oil.

+1 for the HDEO. Any owners manuals to give advisement for the originally desired viscosity?

I have a few antique tractors and I use 15-40 Delo. I put about 100 hours a year on one of them and no problems. Any quality HDEO 15-40 will serve you well.

Any HDEO 10w30,5w40,15w40 would be a better choice.

If you use it in the winter up there, the HDEO 5W-40 would be best.

HDEO all the way.

I run 15w40 Rotella in my 1946 Ford 2N in the summer months, and 5w40 Rotella for winter use.

I too run 15W40 HDEO in my 53 NAA Jubilee.
