I just replaced my gear oil with redline MT90
Since there has been a weird clicking sound from the area of my shifter, i donno if its the coins in the cupholders, (which i removed but it didn't sound like clinking)
I spilled a little oil, but i put all 3 qrts in, (manual says 2.9) but it didn't spill over like ppls said it should.
Is it that big a deal, or maybe i was on an incline or something.
As for the results, the stick moves quicker with less resistence. Good stuff! wasn't even that hard to change, just make sure you have a 23mm socket (took me forever to find one)

 

I wasnt really paying attention when I was adding the third bottle and heard some noise and it was just pissing out of there into my drip pan. I think all thats nessicary is that when you put a finger inside the fill hole, you can feel fluid just below the top of it. Thats exactly what I did and everything seemed fine.
