Really? Do tell? So 20W oils were better in the 40's?
Reading and comprehension lacking...identify where I said "better"...be specific.
they are DIFFERENT...people keep claiming that 20W20 proves that "20s" have been used for years, when they were very different oils...you brought them into the discussion.
J300 was modified to include the HTHS minimums, and the minimum (and target) for the 0W20s is typically 2.6, while the 20W20s were typically 2.9+, the "minimum" for the 30 multigrades.
