The M1 filter I got says "012920AB 09:20"According to Mobil tech support, since 2009, the date code has the following syntax. abcYYMDDd where abc are three characters representing plant code, YY is two digit year, M is a letter indicating month as specified by mva above, and DD is the two digit date. The trailing d is a letter indicating production run.
The code on Mobil 1 oil I recently purchased is 10220B03A. This stands for plant# 102, year 2020, month February, day 3rd of the month, and 1st production run on that day.
This code is hard to read. It is very lightly etched into the back label on the bottles. You have to try viewing the label at an odd angle against a good light source to be able to notice the code. See the attached picture.
