I worked and hung around in a lot of them in the late 50's and 60's. Generally just any heavy wt. oil will do just fine, it's a long way from rocket science!

I'm not sure why 'thick'. Maybe there was a sloshing consideration. As the shop flunky I serviced the air cleaners. The oil reservoir had a level mark stamped into the pan and I was told never to overfill them. I assumed if it were overfilled the excess oil would choke off the incoming air, this led me to believe that light weight oil sloshing around in the tub might cause problems too. I could have been sniffing too much solvent.

The thicker the viscosity the less chance of sloshing from G loads from accelerating, braking, turning and engine vibration simply make sence.
Even though all that is true about the recomendations for using a special #50 oil, every one of the shops that I worked in and hung around simply used the most readily avalable heavy earl!
That was back when oil bath air cleaners were common place.

I was just wondering, I convert everything to paper elements anyway, except tractors. Some of those are almost impossible to fit anything other than the oil-bath to.
