I run Castrol Edge 5w30 when I change my own oil on my WRX and regular Syntec 5w30 on my gf's stock engine'd WRX. Engine builder uses Motul X-Cess 8100 5w40. I won't be able to run a UOA any time soon since it's a new build and still breaking in.

I just did my first oil change with T6. I figure since it was cheap and heard good sh*t about it from those who whack off to it. If it doesn't impress me, I'll go back to Redline 5W-30. I used to be a Royal Purple guy. It was time to look beyond the purple stuff...

I run 15W-50. I have run this since i found my style of driving demanded a stronger oil. I have run 10W-30 on track and my oil pump died and cooked my block at 140 degrees Celsius causing piston slap on #3. I ran 15W-50 in one car and had 5W-30 in another, end of the day with same runs, 5W-30 engine ceased up and 15W-50 engine held up and is still on the road today after a mechanic told me the engine was done 50,000 KM ago. In this heat, i would say a higher grade is essential.

Switching to Eneos 5w30 Full Synthetic GF5.
$6.99 for 1qt, $24.99 for 4qt (gal) with miltary discount at Redline-Napa.
I recently decided to drain the T6 5w40 1200 miles early because it dropped my MPGs and makes the engine feel sluggish. I could care less about the T6's UOAs. I just wanted to see what everyone and their brother was hyped about with this whack-off oil and it's apparent that I find myself totally not impressed with it. Although my engine is totally sound, the lesson I learned is don't always believe the forums and stick with what always works for you. I was a RP/Redline oil guy and never gave me problems but I am confident that this oil will do fine because it's made in Japan. Yosh!!!

been using t6 since I've owned the car. she's at 8200mi now i believe. run's strong, little louder than when i first got her. but so far everything feels smooth. going to give amsoil a try somewhere in the future though, if i can find a dealer around me.
