I know this is splitting hairs, but of the 2 which is the better oil? Both are SP syn-blends that are about equal in price at Wally. Does Havoline use the Chevron Isosyn group II+ base oil?
Isn't "Isosyn" just Chevron's marketing wank saying that they use hydrocracked basestocks refering to the catalysed wax hydroisomerization process, from what I've been able to ascertain Isosyn refers to "grp II+" and "grp III" base stocks.
