Damn you got a deal. I used it in my Wrx and currently use it in my FXT and gfs Lancer. No complaints here. Im also trying to find a wholesale vendor so we can switch to it in the shop too. (currently have Pentosin and Lubro Moly)

 

I've used several oils.
I never had a problem with the T6.
For a 5w30 oil I like Pennzoil Platinum Full Synthetic (oil seems to hold up/look the best after a change).
For a 5w40 I prefer the Motul 8100 X-Cess (only oil I use in the STI, built motor)
