G35 Tow Vehicle.. What synthetic gear lube best for rear dif.

[Road Ruler]

I am towing a camping trailer with our G35 and want to go with a synthetic gear lube for the dif. What would you recommend as far as weight and name brand.... thnxs!

I would reconsider that if the G35 has a silicon bushing isloated subframe like the larger V8 cars. Definitely add a transmission cooler at the least if you proceed.

as for the rear gear oil,Redline gets my top vote for its group 5 polyol ester basestock for max. protection and a slight boost in mpg-- mobil 1 or amsoil are also safe choices

Any synthetic would work, in the same weight as the factory fill.

how much does the camper weigh?

Not sure about the exact weight but most of it is aluminum and is a pro set up with custom receiver etc. Towing is such a pleasure with the G. Power, handling, control.... it is all there. We have a large external transmission cooler and brake controller. Two years of towing and all is well. Sweet set up.
