Is anyone using Chevron DELO 400 Multiviscosity (W20-50) in their 4-108 ? Considering swithching over from straight 30W

There is nothing the matter with using multi viscosity oils. Actually 10 W40 would be closer to the 30W you are using. You may see a slight increase in your oil pressure. The important thing is that the first letter that you see in the circle on the oil container has to be a C and not a S. C stands for compression ignition and S for spark ignition. The letters after that address the additives in the oil.

Thanks Sandy. I'll confirm letters. In retrospect, I am using Delo 10W40, not 20W50.
