Yes. Mobil 1 is a true synthetic and of the big oil co. US brands the only one that can be sold as "Full Synthetic" outside the US. My BIL was a maint supt. of a power plant and went to a lubrication seminar a few years ago and the question was asked by the engineer giving the training and he stated Mobil 1 is the best because all of the molecules are the same size. Will it truly make a difference? Only you experience will tell over time.
