I use excessive motor oil.

I have an 86 international. It tends to use ALOT of oil, like 4 quarts every 500 miles, sometimes does better. Any ideas?

Is it burning the oil? Leaking into the coolant? Or just plain leaking out of a seal onto the ground?

Steve asked the big 3 questions. Losing that much oil should be obvious if leaking out, or if burning, you should definately notice blue smoke both starting and running down the road at that rate -- and probably oil film on the body at the exhaust.

I got an idea but its prolly not what you want to hear, Rebuild the engine and replace the rings, its alot of work but you will be glad you did! By the way what type of engine is it , international engines can be had for a decent price i have seen them anywhere from $1,400 to 2,500 but it depends on the engine type let me know and i will link you to a few sites with good prices.

I've seen a good share of 6.9's that burned up to a gallon of oil between fill ups. (about 400 to 500 miles) I don't recall any blue smoke but I do recall loads of black smoke. We never did worry about the amount then when oil prices were at a 1/3 what they are today.

Well, occasionally I see blue smoke, but not always. I figured it was burning it, which means I should rebuild the engine.

Ive always wanted to rebuild a diesel anyways, so I;ll probably do that in a few months.

I have a 6.9LD International. Sorry dont know more than that. Ive already driven it 4000+ miles from asheville NC, to virginia beach. across virginia, down towards texas, across texas, to sandiego CA.

I didnt have many problems, aside from the water pump breaking in durham NC, after I fixed that it was fine.. however it did burn lots of oil the whole way. I went through several gallons (good thing it runs on veg oil, cuz thats where I saved tons of money).

I am expereincing(automatic) transmission slippage now, not sure why. Didnt do that anywhere on the trip. I think the sandiego mountains may have something to do with it. Gonna dig into things next week.

I don't know about the 8.2, but being that it was Detroit's first attempt at a 4 cycle diesel, it does share a lot of design features (or quirks) with the old two strokers. The two stroke detroits earned a reputation as being "Leaktroits." They had breathers that weren't necessarily poorly designed...in fact, they worked the way they were supposed to in that they vented away excess oil....but they did lead to plenty oil puddles. As I recall this is more of a problem when they operated for extended time periods at higher RPM's like highway speeds or in stationary settings like gensets. Of course I'm not detroit mechanic....this is all stuff I've absorbed from talking to the people that are or have a lot of experience with them.

BTW....the 6.6 Ford hasn't used a measureable amount of oil since I've owned it, even with about 750 new miles on the ticker.
