I changed my gear oil to Amsoil Series 2000 75W-90 today. Great, but I couldn't get the filler plug undone at first. Well, I found a handy use for the factory jack. I was able to put it underneath the ratchet handle and raise it until the plug broke loose. This worked very well, I might add!
The rest of the process was pretty standard. Drain, plug, fill, plug!
Oh, I almost flooded the valley with the Redline River!
I forgot to undo the air release on the oil pan and when the oil ran out it filled the top of the pan and almost ran over into the driveway. Luckily, the pan I have holds quite a bit of oil on top.
