I've been running 75w-90 SVG since the truck's had about 10'000kms when I did my first drive line fluid change. I change the fluid about every 80'000kms. My main reason so starting now is because I've switched to Amsoil 75w-85 and I want to see how that affects things.
I tow and haul over 50% of the trucks capacity often, primarily drive on the highway and live in Northern Alberta which has a climate of -40*C in the winter to +35*C in the summer. It's very dry and dusty here.
