Been hearing all sorts of noises for a while, so decided to send in a sample. Report came in today; odometer is at 55k miles. Used Motorcraft semi synthetic for about half of them, then switched to Motorcraft full synthetic. So, hopefully it's mostly crappy pulleys.
10,041 miles on sample...no oil added.
Pennzoil Platinum 5W-20
