Ford mustang gt 1996 v-8 {mileage stopped at 78500 2 yrs ago.} Odometer does not work.

every 2 or 3 months I have to add a quart of oil to the engine. No smoke comes from the rear tail pipes and no oil stains on the floor/pavement where the car sits/park? Replaced plugs no sign there of oil?

About 3000 to 3500 miles for three months of driving. Trip odometer does not work either!

What type of engine? Ford maintains that using a quart of oil every 1000 miles can be considered normal, especially for the the older V8 engines.

Mostly the oil goes past the rings and valve guides. As the the miles build up and these parts wear out, the oil consumption will increase. You have maybe 120,000 miles on the car now (?). If that motor is well taken care of, it could approach 300,000 miles, so you're good to go as far as lifespan.

I forgot to ask, this is something that has always been the case? Or is it something that has recently become more noticable?

I have had the car since march of 2006 and recently notice since last winter. My wife's cousin bought it brand new then My father-in-law bought it from him then I got it from him. So I am half way I guess restoring it! Have a different question about tire wear? My front drivers side outer thread showing wear, just about one inch from where the threads begin from the outside section. About 1/2 inch wear only. Other side is ok and the passenger side is ok also. Had new tires put on May 2007, then new wheels late june 2007 (16 inch cobra R wheels). Kept the same new tires that where put on in may on the stock wheels. When I put the new tires on I had the tires allign-- thrust allignment. Could this be a tie-rod problem?

Yes, it could be an alignment problem. Does the car pull noticably to one side or the other? What is your tire pressure? If it's not an alignment problem (most likely camber or toe-in) then I would guess an under inflated tire. You would have heavy wear on the outer on both outer sections of the tire though, not just one side of the tire.

As far as oil consumption. I would guess it's normal. Check your PCV system as well. Sometimes the little oil drain hole in the valve cover becomes plugged allowing oil to be sucked into the vehicle intake. Makes the car run somewhat rough. It will actually suck quite a bit of oil.
