Hey fellas, I have a 86 cj 7 4.2 Motor is rebuilt and has aftermarket cam. Motor has 4,000 miles on it. Im thinking of going to full synthetic motor oil. My auto tranny rebuild is not a year old yet and Im thinking of changing the fluid in that (shop probly used nothing special. Im also looking at changing my transfer case fluid as well - never been done. Heres the question. what are you using for your motor, auto tranny and transfer case? Any special reason you went with those lubes?
