I know this was talked about before,this is my take on it.
2004 chev 1500 excab
2wd
3.73 diff
5.3
no mods
before cermax 17 hwy
after cermax 20 hwy
The instuctions call for 2 oz each,engine , trans and diff
6 oz total. Thing is i only put 1oz each in the engine and
trans,nothing in the diff.Im going put 2 oz in the diff and
see what happens
One more thing,i put 2000 mi on it before the later test
for 20 mpg.I got a feeling you have to put some miles on
before it starts working good.
