great advice about the amsoil, being it can get to minus 10 here. where can i purchase it? napa?, and yes i will buy the 80-90 w being that the right seal is leaking slightly
You can go online to find a place to buy Amsoil, or order it directly from them.
The 80-90w gear oil is not thicker than the hydraulic fluid. So, it won't help with the leak. There are some seals in there that you have to replace for that.
