multi-weight oils were not around when the engine was designed or the manual written or updated. Many members use 15/40 oil.

When I first got my Cub I put in 15W40. When I changed it last fall I put in 10W30. I found that it turned easier cold but with warm weather it's smoking a bit and apparently leaking a little at the rear seal.

Next change I'll probably go back to 15W40.

I typically use rotella 15w 40 in everything I own and have yet to have any problems. If it's good enough for big diesel trucks it should be plenty good for old tractors.

In the world of personal biases and opinions, factoring in operator's manual recommendations, modern availability, knowledge and experience, my personal preference for 40+ F temps is SAE 30, specifically Castrol HD30. Daybreak temps drop consistently below 40 degrees F, Castrol 5W-20, since I have 6 volt positive ground, and where I live -22 F is by no means uncommon in winter, and I need it to start for snow plowing.

Edit: Although, to be honest, I have seriously considered the Shell Rotella T5 Synthetic Blend 15W-40 on more than one occasion.

For many years I have used 15-40 Delo in my Cub, H, and JD 1020, works very well and no issues.
