According to my "1986 Light Truck Owner Guide Supplement for the 6.9 Liter Diesel Engine" says 10 quarts with a note that says, "includes one quart for filter replacement."
Didn't mean to come across as preachy, but I would go with 11 quarts.
My Daily Driver
1986 F-250 2WD, Regular Cab, LWB, 6.9, T-19, Sterling 10.25", open 3.55's, XLT Lariat, Texas Sesquicentennial Limited Edition, No Restrictor Plate, manually switched high idle/advanced timing, and an awesome custom shift knob thanks to Bruce Roosa / Koolknobs.
279,000 miles and counting, hoping for a US Gear OD and a Hypermax Turbocharger one day.
My first truck:
1982 F-250 4WD, Extended Cab, LWB, 5.8, C6 to T-19 swap, BW 1345, Dana 44 TTB/Dana 60 Semi Floater, open 3.55's. About four different colors (not counting rust), currently on loan to my little brother. Maybe one day it can be home to a 6.9L too.
1992 F-700 Flatbed w/ dump, 7.0L BIG BLOCK GASSER, 5-speed trans (Clark?), 26,000 lb GVWR. Rides like a tank
