[QUOTE=maxcichon;695072] I bought 5 and I figure I'm golden until ~ 2024.

Ummm,I'm confused (a little), I bought the 5 jugs/filters thing and those 5 jugs only give me three XF oil changes. Now if I change my oil as recommended, thats a max of three years given my driving milage style. Did you mean that you bought 5 sets of 5 jugs?, since that would equate to 15 years maximum at one change per year?
