aT AZ today and saw some Castrol Syntec 0w30, 4 were MO501xx, 6 had no MO#'s but read "Made in Germany" on the back, and 4 MO22xx. Opened 1 of the no MO's and saw green so I bought them plus the M0501xxs...total 10qts. The "Made in Germany" was on the right-side of the bottle meaning it should have a MO# in the 4x-51xxx range. Anybody have an idea what the MO# should be?
BTW, I paid $3.99qt, using the Kragen's coupon and AZ willing to price match.
TIA...bgin
