tnx
M1 and Mobil 1 Extended Performance are about 1/3 PAO. They will probably run smoother than others. You also get the more potent trinuclear moly.
What vehicle is this? The PAO-based Mobil 1 Extended Performance 0w20 could be the best choice. If too expensive, then half-PAO-based Mobil 1 Advanced Fuel Economy 0W-20.
