It appears many have experienced the recent M1 price hike, and are not happy, myself included. Yesterday, I bought 7 quarts of Pennzoil Platinum instead of M1EP. I can't justify spending over $6 for a quart of oil when it has been proven to be no better than most other synthetics. So, with the vanilla M1 close to $6 a quart, and the EP breaking through the ceiling, are any longtime Mobil 1 users going to look for alternatives? P.S. Has anyone checked the prices on Mobil clean 5000, and 7500? Those seem very high to me for what appears to be mediocre oil.
