I agree with Dennis in that you couldn't do much better than the 
Mobil 1 15-50 motor oil in your manual tranny.

It was Eldon McFarling of diesel engine fame that finally convinced 
many of us that the old Manuals weren't gospel when they specified 
gear oil in the trannies, and I maybe I've been the strongest pusher 
of the Mobil 1 as a very good choice for that application, but 
regardless of my prejudices in lubrication, believe me when I say 
that you will be very happy with that choice.

In regard to a lifetime fill, I'd be perfectly happy to leave the 
Mobil 1 in there for the life of the vehicle.

So that I avoid being found out as a hypocrite one of these days, let 
me confess, I use Amsoil lubricants in all the running gear on my 
Dodge diesel.  Very expensive, but they give me a lot of confidence. 
I don't recommend the Amsoil to others. If asked, I suggest they use 
Mobil's synthetics as I do in my Scout.
