I remember when Mobil went from Tri-Syn to Supersyn....many on BITOG thought it was a downgrade before eventually accepting that it was in fact an upgrade.Mobil was of course the company that pioneered using all three of these bases together (tri-syn) and has stated, previously, to use all three when formulating, in varying quantities of course.
If using the 3 base oils was desirable...was it cost or performance that made Mobil make that change (from Tri-Syn to SS)? Of course like most things on BITOG....the answers will be opinions.
PS: Since this thread is on 0w16 oils....I'm wondering if anybody used the discontinued Supertech 0w16 which Walmart 'cleared' @ $7 for the 5 quart jug? I wonder if Warren made theirs as stout as the name brands?
