After my sucessful application in my parents Grand Cherokee (Which as you may remember had a seal leak which auto-rx promptly fixed). Im trying it in my work truck; right now a 1995 F-150 with the 4.9L. It's got almost 200K on it so even with my diligent oil changes theirs still some sludge in the motor. Ive got a full bottle in their right now with about 700 miles on the oil. Im gonna change the oil filter at around 1300. I'll try to cut it apart and post the photo's. I'll keep everyone updated as it goes.
