One thing I didn’t mention in my writeup of the wacky Gambler 500 road rally was that my Jeep overheated, and it was all my fault. When I returned from the rally, I frantically shipped off an oil sample to a lab to have it tested. That decision may have saved my engine’s life.
To find out what happens when you forget to change your oil, I sent a 12,000 mile oil sample to a laboratory. The results are not good, and should serve as ammunition to convince your stubborn friend or family member that no, it’s not “going to be fine for another few months.”
