I've had several:
1. A 1993 Chrysler Fifth avenue. Used a quart every 1500 miles from new. Get rid of it at 68K when the transmission went out and apparently could not be repaired properly under 7/70 warranty.
2. My first car, a 1968 Mercury Montego convertible. Used about a quart every 1500 miles. Liked the car, so had the valve seals redone. Was fine after.
3. My college car was a 1979 Ford LTD. It consumed about 2 quarts per tank of gas. Dealt with it by buying cheap oils by the case. Didn't even bother taking them out of the trunk. It made it through college graduation. It had 80K on it at dismissal.
4. I had a 2000 Ford Taurus that started using a quart every 2-3K at about 200K. No big deal. Topped it off with some 10w30 that I had handy in my stash from prior endeavors.
5. Same thing as #4 with the Ranger in my signature. Top it off with whatever is handy and keep motoring.
