I changed out the fluid in the reservoir tonight and man was that stuff black and thick. Funny thing is I was pouring the old fluid into an old Coke bottle and when I got done, it looked just like Coke. I got 13 oz changed out with Valvoline Synthetic. I figure I will run it about 1,000 miles and then do it again.

Now you bring that coke bottle somewere to see if people can tell whats in it lol jk

What method did you use to change it.

I used a hand held vacuum pump and pumped it out, measured it, refilled with new fluid. I also checked it after my next driving trip, it was a little low so I topped it off.
