I purchased new; after 124,000 miles I have not touched the motor. It is a V6 and have never added oil between changes. Except for replacing tires, brakes, and front ball joints the car is all original. It is sad to see the rating on not just Ford, but all American vehicles. I have had 6 Ford vehicles and 2 Thunderbirds 89 & 95. Both over 125,000 miles. 2 Town Cars, 92 was sold at 135,000; the 98 I still have with 93,000 miles. The V8 does use oil, but the V6 on one of T-bird's and on the Explorer never used oil.
Good strong motor, good car. too bad they get a bum rap.
Get the V8 to quit using oil. I had a 1954 Ford V8 and that never used oil. I also still have a 1967 Olds V8 100,000 original miles, never used any oil.
