Greetings Bruno

Bi-Tron is nothing like Slick 50. As Bill Davidson wrote the oil is a
positive charged oil, just oil, nothing else. I have used it for a
couple of years. Put the 2-4-6 in my tranny and frontdiff, about 8 to 10
ounces to my regular fluid. In cold weather I don't get the 1st to 2nd
grind anymore. I use the engine formulation as well. I also have a
contact who maybe able to direct you to a local source. Phil Whyte at:
