The car and its parts will wear faster but that is about it.
Town Cars in NYC Taxis are running 1,000,000 miles and more. I would advise you to use the best 100% Synthetic Oil in the World AMSOIL. AMSOIL is guaranteed to run 25,000 miles on the same oil and filter as well as giving you a 6% savings on fuel. For your 1997 LINCOLN TOWN CAR 4.6L 8-cyl Engine Code [W] You would need:
5 Quarts of SAE 5W-20 Signature Series 100% Synthetic Motor Oil (ALMQT)
1 25,000-Mile Ea Oil Filter (EAO11)
Driving lots of miles in a short amount of time is not hard on a car. Getting behind on oil changes and maintenance is.
You should change the oil every month. There are oil change shops that can do it in a half hour or less.
i bought a 1997 Lincoln town car with 200,000 miles now i am at 226,000 miles, i am behind on oil changes the reason i drive so much is because i'm like a private taxi for my family LOL if that makes sense, i haven't had any problems with the car only a rear axle shaft seal, now back to the question
