While at Meijer tonight, I made my usual trip to the oil aisle to see what was on sale. I was looking over the oil filters and compared Fram Ultra to Mobil 1 EP. When I opened the M1 filter to compare it to the Ultra, to my surprise there was a plain ole Fram Extra Guard in there. If you don't already check the contents of your filter box before buying it, this is reason to start that habit.
