What does you Oil Level Display show - is it over-full?
When I changed mine w/filter I used 8 qts, and the display ended up at the first mark below full.
Maybe he meant that he had to charge for 9 qts in order to get the extra .2 quart over 8?
You are right however, the manual says 2.05 gal (7.75 liters) with oil filter change (1.98 gal/7.5 liters without filter change).
