I often see that 5W-50 synthetics are disliked by some as they may be loaded with VII, but most (maybe the same guys) love 0W-40 oils as “great”, “universal“, “good base stock”.
The viscosity spread in these two oils are almost the same. Can’t 5W-50 have as good a base stock or better as the much loved 0W-40 oils? I have used the 0W-40 M1 FS for 22 years with no complaints and have the 5W-50 in my BMW R1200R with no worries.
