I was buying Formula Shell Synthetic at BJ's for about 2 yrs / 15K miles. Even with the $10 coupon it was no great deal at around $4.50/qt. I haven't seen it for my last 2 trips there....it's been replaced with Pennz Plat 10w-30....which this month is carrying the $4 coupon...or $19.99 net for 6 qts, much cheaper than the FS ever was. They must have a lot of 10w-30 to get rid of.
The Formula shell conventional and syntec have a makeup similar to Mobil Super Synthetic. The SOPUS FS is somewhat different vs. the SOPUS Pennz and QS, which seems odd to me (less Ca, more Moly, and a lot of Boron).
