Getting ready to do my yearly oil changes in my 4runner and Corvette. No one around here seems to have M1 in stock. Turned to good ol Amazon to order some, quantity of three 5qt jugs of M1 5w30 high mileage extended protection and a M1-113a filter that no one had in stock either. Got the package last Monday and opened it today, noticed the bottom of the box was soaked with oil now, it wasn't when I got it on Monday. Only received two jugs instead of three. Ok whatever, things happen, go online and go thru the order issue process. Said I was missing one jug, and Amazon resubmitted the order for 3 jugs. Called customer service and explained I only needed one, and the agent said I could return the first two. I said the oil had leaked slightly thru the plastic bag the jug was in and the box bottom was soaked with oil from one of the jugs. Looks like the seal broke open during shipping and I maybe lost a few ounces at most. The agent apologized and said please keep the two jugs, and the other three will be there by the end of the week.
