Eco Boost Owners - Anyone using a Tow Tune?

And the more 'modern' exotic additives are Molybdenum Disulfide and Tungsten Disulfide
that has much higher temp ranges and plating attributes than Zinc and Phosphorous

Can't be used on limited slip nor 'some' lockers that use clutches...to slippery

In theory, diff lubrication should never allow metal to metal in there...but in
the real world it does...too often

Non-synthetic's now have higher temp ranges, but synthetics still hold the edge
on temp range and shear (film strength at temp/PSI)

A very old discussion in my circle has been the track diff's (smallish) compared
to our light duty trucks and external cooling on the pro's setups

Is it because they stick with the smaller dia ring gear to keep the pumpkin
small (ground clearance) or are they keeping weight down? or both? or ???

Would they then need external cooling if they went to larger dia ring gear?

Germane here because so many take things out of context....see racers
using something and think it's the thing to do on public roads
