I like it! I know this isn't scientific data but my Jeep just puuurrrrrrss. It's so smooth running with the new Syntec. It's on the thin side of a 30 weight. Oil pressure at 55 running 1500 rpm is 72 psi, AFE 0w30 was 70 psi and Rotella T5 was 76 psi. Warm idle is 33 psi, AFE 0w30 was 30 psi. I have a mech gauge if any one is wondering.
