Oil capacities in the XI are a much debated topic. For some reason it seems that some XIs hold almost 8qts while others (Myself included in this bunch) only take ~7 to reach the full mark.

The reasons for this run the gambit-- From 2 different oil pan shapes (see below) used on the XIs to the updated dipsticks that register full @ ~7qts. There has been no definitive answer as to why from what I have been able to research. I have also seen printouts from owners manuals with different figures. Generaly speaking it "seems" that the higher capacity figures are mostly from earlier production XIs but not always. Clear as mud yet?


Same as what I have (7 Qt pan):
