I noticed that Synlube sells one weight of oil.....5w-50. Would this weight be safe to run in any vehicle? When is thick too thick? I have seen some 0w-40's and 5w-40's and 15w-50's but no other 5w-50's. What advantages or disadvantages would this wide spread have?

Lots of VII. The one UOA I have seen of this showed that it sheared down to a thick 40 grade. Don't pay $35 a quart for PAO oil.
