excessive oil useage in Grand Marquis?
My 2000 Grand Marquis with 15,000 miles on the odometer uses one quart of oil every 1500 to 2000 miles while on trips. I change the oil myself and am very careful about keeping records. Dealer seems to feel this oil use is within accepted specifications!? This is the 4.6l v-8. I had the same engine on a '97 Marquis that had 91,000 miles on it and never burned or used a drop of oil. There is no sign of oil leakage on or under the vehicle. This is crazy! Anyone got any suggestions? It looks like the dealership is not very sympathetic. I'd sure appreciate any input.
