My 94 F250 460 with about 68,000 on it burns maybe a quart between the 7,500 mile oil changes. I use Valvoline Syntehtic 5W30 BTW.

Normal all depends on the brand of engine and who is writting the manual. Some car companies believe 1 qt every 1,000 is not unreasonable. IMHO 1qt every 3,000 is about normal for an engine with miles on it.

YMMV, your mileage may vary...
