In the SL days, I have used Formula Shell for 5k and Chevron Supreme for 5k, and the drained oil is thicker for FS (and way thicker for SuperTech that I no longer used) than Chevron.
Since everyone has to use GpII and GpII+ blend to make SM, they are all pretty good and should last 5k now. Buy on price with confidence.
Isn't IsoSyn from Chevron a GpII+? If so, then it is slightly better than FS and equivalent to Pennzoil?
