Hello! I haven't been on here for awhile. I think I had an account before but I couldn't get it to work so I reregistered. Anyway oil is of interest to me. I've lurked on here and found a lot of info.
So here's the question. I'm working on a 1937 Case model L. The manual calls for sae 10 or 10w using its oil numbers exactly. Unless you are in hot weather then use sae 30. I was wondering if it would be OK to use like a 15w40 diesel oil year around in this old engine. It's probably an old bypass engine. I was looking at using the Delo 15w40 diesel oil as I believe it has a good level of zinc in it as it probably has flat tappets.
Thanks! Chad
