These cars have been out for 3 years and it seems many are reporting up to 3 quarts of oil usage per 1,000 miles. This is “normal” according to the owners manual. The engine is an 800 HP V12 running up to 9,000 RPM. No turbo, naturally aspirated. It uses a 5W-40 and the manual states that one should not run high RPM until the engine oil gets above 160F.
I had one of the original Ford Expedition SUVs from new to 45,000 miles until I traded it in. It was the only vehicle I ever owned that consumed oil. From day one until the day I parted with that truck it used the same amount of oil. It was around a quart per 1,000 miles. I thought at first the consumption would go down after the engine was fully broken in but it never changed.
I have used grades of 20 to 60 in single engines that never consumed any oil. So I do not think it is an issue of grades.
The current 812SF has 1,300 miles and used 2 quarts in the last 500 miles. The oil in the oil tank (dry sump) is clean, odorless, and there is no smell of the exhaust and no smoke. No leaks underneath. The oil capacity is 14qts. Where is the oil going?? Thoughts??
