I'm not going to wade into the synth/dino debate, but I will say that whatever oil you use, err on the side of higher viscosity.
These engines are brutal on viscosity, which I have confirmed with 3 used oil analyses. Each time the analysis has come back one grade lower than what I put in, e.g. 10w-40 had broken down to 10w-30 and there was no fuel dilution which caused the lower numbers.
The upshot is, if you use a X-30 oil, it will likely break down to a 20W oil which will be out of spec for the engine. So the 20-50 is good, IMHO.
