My Mustang will pass the 75K mark tonight. Going to my friend's place in Santa Ynez to try out one of the lifts in his small average middle class detached garage. Changing the oil, manual trans fluid and rear diff fluid. Debating between all Motorcraft for the trans and diff or Lubri-Moly in the diff and Pentosin in the trans. All are in my stash. The engine will get Liqui-Moly 5W50.
