Dr. T, I think more than once, I've posted in here about my buddy the Queens, NY City auto repair shop guy. He owns his own shop. He has the maintenance contract for a number of New York City airport limo services. They all use Lincoln Town Cars.
The mileage on those Town Cars would make ya **** in ya pants. 1/2 million miles is not extraordinary for these boys. Many have in excess of 1 million miles.
The oil used? Castrol GTX mineral/dino oil. 10w-40 most of the time. 10w-30 GTX occasionally, when they have a really crazy snow-bound East Coast winter.
