Well, I'm down in Mexico for spring break, near Guadalajara (not in Cancun, Cozumel, or Puerto Vallarta). Anyways, I went over to the Wal-Mart in Guad. to take a look at their oils in the auto section. Really, only two things stood out to me. First, it seemed like every bottle had "API SL" clearly and largely marked on the front of it...don't see that in the U.S. The second thing I noticed...the lightest grade is a 40 weight...no 30 or 20 weights to be found. Heck, the high-mileage oils were only in 20w-50! Also noticed that there was a much higher selection of 5w-40 oil than what we see in the U.S. Also, there were many more straight-weight oils on the shelf...mostly 40 weight. Justin.
