i also went with the amsoil sever gear fluid back when i installed my mag-hytec cover and didn't add any modifier to it and its been running great for the past 9-10Km miles. i also relocated the axle breather hose i suggest you all do it! or else you will end up with chocolate milk like me lol its simple just add some hose to it and run it up somehwere high i ran mine between the cab and the bed and no water no more for me!!!
