That anti-foaming is SPOT-ON. I have run AE on trucks with poor ICP and 1211 codes and found out the saavy owner preferred walmart-brand oil cause its a little cheaper. After putting Delo or Rotella back in it the problems went away.
Jason, I almost have to agree with you here. I do not know this guy personally so take that for what it is. I definitely agree with you. May switch to Rotella T6 at the next change.

Good luck on finding a solution. I would say it has to be the oil. Especially if you don't have signs of a leak anywhere.

That engineer may be confused with the oil specs for Ford's new 6.7 diesel engine design. I believe that one gets 10w-30.

I never knew that Ford actually had a anti-foaming agent available for purchase. Very interesting, I wonder what the part number is. For years I've been wondering if the 'anti foaming' agent was real or internet lore. On my own trucks, I have noticed....or imagined in my head, that the engine would begin to sound a little different once the oil had about 4000 miles of use. Lab analysis didn't show anything different between young or old oil so I wasn't sure there was anything to this 'anti foaming' idea but it does seem like my engine runs smoother and quieter on new oil and somewhat less smooth and a little louder on old oil. Again, it all could just be in my head....

I notice that too Greg. Not as much as a i do when I top off the fuel tank though. I think part of it is in our heads, but there's something to it for sure.

No signs of any leaks (knock on wood). 1 drop from the CCV hose all last night.

I was thinking about this yesterday.

I wonder (if possible) how much oil injectors themselves can consume? I mean worn injectors with internal leaking of oil past the o-rings to the fuel side and into the motor.

This way would consume oil, no leaks, no wet pipes, just use excess oil.

Snowseeker, that is what I was wondering and the reason for my suggesting some things earlier in the thread. I wonder if the o-rings don't need refreshing. It is just a thought though.

I mean I do see this as being a possibility but I sure hope it is not my case since the injectors are only about 3000 miles old.

I remember that from your earlier post. I wonder if an o-ring didn't get a tear or something when being reinstalled. It is a pain in the butt, but I have no clue what else to think.

That definitely is a possibility but all 8 did snap into place fairly easy. None went in any harder than the others. Also, as far as I can remember, it has always seemed to use oil. I have had a small leak in the EBPV and the LPOP up until about a month ago. Got all of those leaks fixed so thought that would stop the consumption but it may have just slowed it.
Last time I changed the oil, I only put in 3.5 gallons to fill it up and if I remember correctly, it used to take 4 gallons. That I guess could account for a couple of quarts of consumption. How many gallons do you put in on an oil & filter change?

Do you have a crank case vent that is not stock?

It may just as well be an oil user.

I add 15 quarts or almost 4 gallons of oil at each oil change. I am running Royal Purple and have been with about four or five oil changes that weren't since I got the truck. RP is more expensive that the others, but I believe in it and use it because of that belief. I don't push it on anyone, because everyone has his or her favorite oil. Your truck might like Amsoil, RP, Delo, Rotella, or any of the others. I am just at a loss as to how you can have a consumption issue, if the injectors have been recently refreshed, no leaks that are known or visible, and there isn't a coating of oil in your coolant.

It just stumps me, because I don't have the issue. Doesn't mean it isn't normal, just not for my rig.

Yes my CCV is routed over top of the master brake cylinder and then dumps out down by the transmission crossover bracket.

Stick a bottle on the end for awhile and see how much oil it is dumping.

Have you tried the oil cap trick? While running take the oil cap off, flip it over and stick it on the spout and just guide it from rattling off. Is there enough air to blow it up and off the spout?

I am right with you. Definitely think I may change brands to see if it is just being racist about Schaeffer's. thanks for all of your ideas!
