Just returned from a little vacation, driving out to Roswell NM, Phoenix AZ, San Diego CA, Albuquerque NM, back to Roswell NM, then back home to Central Florida. While on vacation, I read somewhere on this forum that K-Mart had M1 on sale for $5.00 a quart. Well I returned a few days ago, and while driving around today, I saw my K-Mart so I said, what the heck, I'm sure that they are all sold out, but I'll stop in just to see what they have. They had a lot of M1, all types of M1, on sale for $5.00 a quart. I don't normally buy M1, but I could not pass this up, so I purchased 10 quarts of the 5W-30 EP and 10 quarts of the 10W-30 EP. All their M1 cost the same, no matter which M1, so I got the EP. This should last me for a while.
