berserker-
Possibly you may have misunderstood my post:
You must remember when HD was totally against synthetic oils ??
They even threatened bikers with voiding their warranty if syn was found in a motor..I know, I was servicing many bikes & their owners told me this very thing.. I called Milwaukee & they said if the oil was found to be at least equal to HD dino oil, warranties shouldn't be voided..
Along comes the 1999 TC 88A & HD realizes they run 240*-280* & sometimes hotter. So they have to back peddle & get their own brand of Syn on the shelves ASAP.. This is what happened..
Plus the bean-counters wanted a sharte of the syn pie (read $$$)
Hell I have Mobil 1 in my tractor, & have for 10+yrs, & in everything else I have..
Just for the record, back in 1984 I was saying that shovels were better than the (then) new fangled evos...
