I suggest the OP purchase whatever the "best" bargin is, because there will be little to no difference in a series of consistent UOAs.
I totally agree with this statement. However, I stick with Rotella in my bike because it requires a JASO MA approval. I have a written statement from a Shell engineer confirming that Rotella meets this spec. I will only stick with Rotella during warranty, and once that is done, I'll go with one of those 3 name brands based on price point.
Nice thing is, I now have a pick-up that uses the same stuff (10 qts per oil change), if you include the 1/2 qt my mini race bike uses, buying in bulk makes sense now.
