5.0 oil consumption

If you cant see any oil under the truck, I would be willing to say that the Valve Guide Seal is the first suspect. Piston ring would be the second possibility.
I wonder why the OP hasn't elaborated on the mileage or the break-in methods?

I'm starting to wonder about the 5.0 as well between the ticking in my engine that we can't get figured out and the large amount of oil consumption... it hasn't seemed to affect anything yet it drives great and pulls my bass boat with no problem guess we'll see long term how it holds up

My truck used some oil from my 5-10k interval. I now have 10,600 on it and it hasnt burned anything that i can tell so far. I will be checking it every 500 miles until i change it again.

Op; I had '00 with the 5.4 an '06 5.4 and my '00 mustang with the 4.6 not one oil problem. Mileage on my '11 5.0 is just over 12,000. As far as brake-in I had at least 1800 plus miles before I even hooked to a trailer. I didn't "baby" the truck, but at the same time, I didn't beat the hell out of it. I have two mustangs for fun. I certainly don't need to abuse my truck.

Checked the oil this morning at 4343 miles (2058 since change). Oil level is still at the top of the cross-hatch on the stick.

Well this morning I took my truck in for an oil change and I checked the dipstick and it still showed full. I also put an oil catch can on a while back and I wanted to empty that and it was nearly full, about 10oz of oil in it from the past 5k miles. I haven't done any towing that just normal commuting for me so I can see where more could be lost this way.

I'm curious to know how the owners with excessive oil consumption broke their engines in. I've done some research on this recently after purchasing my first new high performance motorcycle.
The most consistent information I found described how you need to build pressure in the cylinders to seat the rings correctly, meaning that the engined should not be "babied" during the break in period. Not abused with wide open throttle all the time, but only light throttle inputs are definitely not recommended. The method I used on my bike was no lugging, and no high revving but moderate to hard acceleration especially on uphill stretches. I used the same formula with my new truck.....but is harder to duplicate exactly with an automatic transmission.

The day after I bought my truck we left for a family vacation to the mountains in New Mexico. The first 500 miles before we got to the mountains were highway at speeds from 65-80 and after we got to the mountains I had some climbs where the rpms got up around 4000. So I don't feel like I babied or abused it during break in. Felt like I did a pretty good job of varieying the speed/rpm too.

I prob babied it to much. But from pretty much day one i did some very light towing with it and floored it from time to time. Most of its life has been under about 2500 rpm though.
