Hi. I'm wondering where to find Amsoil Synthetic Gear Lube SAE 80W90 in Alberta (Calgary). And how many liters of oil I need for front, rear and transfer case for my 2005 4runner V8.
Try your local Amsoil rep. But Mobil1 75w90 will do just fine. Your capacities are in your owners manual. You will need crush washers for both diffs and the tcase. I use Mobil1 75w90LS on all 3 in mine. No issues and my dealer recommended it.
