My point is that 0W30 kept same formulation with high dosage of PAO, probably around 50%. Same formulation that has with LL01, lost it, gained back!I was referring to the new 0W-40 formulation, probably will be our API SP when it comes here. The 0W-30 is excellent, but a bit pricey.
I highly doubt new formulation in 0W40 is contributing factor to gain back LL01.
