so before i became a bitoger i changed the rear diff fluid on my new to me pick up (04 f150) i went with super tech 85/140 and lucas. i think it may have been a bad idea because it recs syn 75/90 or 75/140 for towing. its a limited slip diff.
i have thought about going with mobil, synpower, or royal purple.
any thoughts on these products? which would you pick?
