What is the general consensus on this product? I have seen a few UOA's that looked pretty darned good (better than M1) on this oil. I have heard that it could be a Grp3 and PAO/Ester mix, but do not know. With the "free" rebate it could be an option. Wife drives a lot of short trips, some highway trips too; basically not the best environment for an oil to excel in so a syn is in order.
