If you're gonna use mobil, make sure you get the blue dex6 bottle. It's different than the other full syn atf.

Yea, but the Mobil1 stuff says its Dex 3 compatible, which is what we need. Can't put Dex 3 in something requiring Dex 6, but you can put Dex 6 in something requiring Dex 3.

I have Wal-Mart Supertech Dex 6 in mine since it was what they had available. I'm probably going to Federated Auto Dex 3 on my next flush this summer.
