Mobil 1 vs. Mobil Full Synthetic

[BoiseIdaho]

I looked up these two oils at the Petroleum Quality Institute of America because I have used Mobil 1 0W-20 and found the Mobil Full Synthetic at a far lower price. It almost looks like Mobil Full Synthetic is Mobil 1 without the advertising budget, but there are some differences. Mobil Full Synthetic seems to have a higher molybdenum content, which should be good for longevity but not as good during the break in period. Also, Mobil Full Synthetic uses more calcium in the detergent mix, which isn't the greatest for GDI only systems. Also, the TBN number is a bit lower on Mobil Full Synthetic, which suggests the oil run should be a bit shorter. I don't plan to go over 5000 miles between changes, so it probably won't make any difference to me.
