The manual calls for 75/90 gear oil for 90 Loyale. There is only synthetic available at my local stores in that weight. I have some 80/90 gear oil and have contemplated using it. Is there that much difference?
I like the through the wheel well, over the shoulder, around the tree approach to the rear diff but I think the $5 pump or even the squeeze bottle the oil comes in with a feeder hose may just do the trick. I will try and post again after I wash the oil out of my eyes.
