Hello, all, I bought the short one in February 2020 and the tall one in July 2020, both from Walmart. The short one is 3 5/16" and 211 grams and the tall one is 3 1/2" tall and 261 grams. Both are made in the USA, and the only difference in the packaging is the taller one specifies a steel inner core and the shorter one does not. Did Mobil 1 recently make improvements to this filter or is it common to see these types of variances from time to time? [Linked Image] [Linked Image]
What does the torpedo show?
