I am on my 2nd 7.3,,66,000 on the first before she dropped a rod, and about 25,000 on the reman now and neither one ever used a drop of oil in between changes. I usually change between 5-6000 miles and its still on full everytime. Every truck is different though...
Guys, either I'm really lucky or something, but my '99 F250 has 304,000 miles on her now and it uses less than 1/2 a quart (at most maybe an 1/8" below the full line on the dipstick) between oil changes. I pull a 24' gooseneck w/ tractors very often and oil consumption doesn't seem to change when she's working.
As for the gentleman using 3-4 quarts per oil change, as long as you don't let it run out of oil it will run forever. I had an old '68 F250 with a 390 gas that would use 2 qts per day, 1 qt to school and 1 qt home, which round trip was 22 miles!
It got so bad that when I would change the oil in our tractors I would put it in qt bottles and re-use it in the 390. But you know it still runs....

Yep, I haven't been too concerned about it. With nearly 4 gallon's in the pan I'm not to worried about being a couple qt down from time to time.
I see another suggestion in here to just leave it at a qt low. I know mine will drop to the bottom of the hash marks which is 2qt. I just changed it and am heading for FL tonight. If it drops down I'll let it sit there and check it at every stop to see what it does. As long as I've got oil on the stick somewhere, I'm not going to worry too much.

I think that I will check and add mine as needed to keep it full. The differnce in the sound from full to one or two quarts low is worth that.
I will also add a oil preasure gauge in another month or two so I can keep a better eye on it.
just what I was told when asking about my truck burning so much oil, but according to Ford it is considered normal for the PSD to burn 1qt for every 1,000 miles
