Are you running synthetic oil in you engine, tranny & diff.? What differences have you noticed? Yesterday I finally put on the Trick Flow differential cover, and put in Royal Purple Max Gear w/ friction modifier. All I can say is that the combination of running synthetic throughout is awesome. 


An article in the June issue of Sport Truck magazine on changing your oil to sythetic throughout (Royal Purple) got them an increase of 10 more hp & 12 more ft. lbs. of torque at the wheels.
