Both the Valvoline EP and Castrol Edge EP are Dexos1 Gen3 rated. However, the Castrol also holds both the MB 229.71 and STJLR.03.5006 ratings. Dexos1 Gen3 specifically targets reducing LSPI.
Looking at a Lubrizol comparison of the three ratings, it looks like Castrol Edge EP may have the LSPI protection of the Dexos as well as the wear protection, sludge mitigation, deposit formation prevention, and soot thickening found in the MB and STJLR rating.
My question is, which one would be better for preventing sludge and LSPI. Answer is: Probably doesn't matter with early OCIs. What do you think?
