5spd lube

I just bought a '96 3500 with the 5spd manual trans. I've had automatics so this is my first manual. I want to change all the fluids in the truck so I know where I stand maintenance wise. I have read the fluid of choice is Syntorq or something like that, but it seems pretty pricey for a gallon of the stuff. Has anyone used an alternative with good results? Seems D/C is always specifying some sort of exotic lube especially for their products and wondered if it is necessary. If it has to be that then I will buy it, but with all the years of manual transmissions using 90wt hypoid, it seems odd that all of a sudden these things need special oil. I know in some earlier years engine oil was spec'd for gear lube, but I figured it was for fuel economy/ease of shifting in cold weather etc. Any ideas?
