To this point, and likely very well past it, newer oil formulations have been significant improvements in terms of engine life and overall performance.
I cannot see whay this would change with CJ-4 oils, from any manufacturer.
The differences between standard and full-synthetic oils is steadily diminishing. I can see where the ONLY oils we can get will be synthetic based (and this is, IMO, a VERY good thing).
