gearheads say run synthetic.
summit tech guy says sythetic will eat the clutches. he says not to run it ( he suggested some sort of lakewood fluid ).
frition modifier: everyone i have asked says pour the full 4 oz bottle in with the fluid. the summit guys says do not use it unless the rearend starts making noise, then add enough to stop the noise. just my opinion but i just dont trust the advice of the summit tech.
i called my local ford dealership. he said his books only go back to 97 ( rearends are the same as far as i know ) and it called for a 80/90 fluid.
what do i use? im leaning toward using what originally came in the car.
