This is the first time I've heard of any oil consumption problems in FEH. I have 9500 miles on mine and it's not consumed a drop.

As to OCI (Oil Change Interval) I think the 10K interval is reasonable given the reduced amount of idling (always hardest on an engine) the FEH does. Modern motor oil has come a LONG way since the old 3000 mile recommendations were the rule...even my 1995 Volvo wagon had a 10K service interval.

For mine I'm going to use Mobil 1 5w20 (was finally able to locate some at the local AutoZone) which does meet the 930-A spec. Also going to use the Wix filter, which costs half what the Motorcraft one runs and includes both o-rings.
