I bought my Daughter a '93 Mustang LX 2.3 about 2 months ago. I did a rear main seal and an oil change when I got it and a few hundred miles later, it was down a quart, same thing a few hundred miles later. All in all, I figure it lost about 4-5 quarts of oil in about 2200 miles. There are no leaks and no smoke. Car only has about 66k original miles on it (carfax verified) and sat for about 4 years. Runs great and no other issues. Where is the oil going? Thanks...
