Thanks...I changed it and it took 11qts...I wanted to get the Mobil 1 filter but they didnt have it and I am impatient to say the least!!!

One quart of the 11 was Marvel Mystery oil (MMO) that my farmboy buddy said they use in their diesels and he uses in his diesel Tornado!!!

Have any experience will MMO?

Used MMO in my GW motorcycle, but put it in the fuel......... some members on a few diesel forums I visit use it as IP lube in the fuel.

Just a heads up .......

DieselDon
Oil consumption, and the proper checking of the oil levels in Ford diesels comes up periodically. Ford dipsticks are calibrated for hot oil. The 10 quarts in the IDI engines expand about 1/2 to 3/4 of a quart as the oil heats up, and contracts the same amout after cooling. If you check the oil first thing in the morning ( which I grew up doing ) the engines will all indicate oils level below full, but when checked hot, will ( after a 10 minute drain time ) the oil level is usually at full. If you are checking the oil cold, and keeping the level at full, you are actually over filling the engine which will burn of the extra rapidly.
Suggestion: Check oil hot after 10 minute drain time.
Don't add until level reaches add line ( 2 quarts ).
In my days at Ford this often cured, or at least improved, the apparent oil consumption complaints.

PLC is right, less oil consumption at 2 qts. low. Crank can whip oil and ruin it. Thats why the dipp stick says "DO not over fill".

So PLC, sounds like I should be putting 8 or 9 quarts in my truck. 10 or 11 brings it right to the full line when cold (10 with IDI filter 11 with powersmoke). I never knew this, but I also never (well almost never) use any oil.

When I went to a PowerStroke filter I put in 11 qts. When I check it cold it's right on the the full line. Hot it's almost a half inch over. Mine doesn't use any because it's been that way for 3,000 miles. Next change I'll use a little less.
