I have 90 on mine and have been using the Merc 25W40 oil. Its seems like pretty good stock. I've also used strait 40W racing valvoline as well.

I really want to use 20W50 Mobil One but I am scared due to the roller cam

I have been running Mobil 1 15-50 racing with Mobil 1 filter since 30 hours the motor currently has 165 hours with no problems. I have noticed that the oil pressure seems to be more stable especially after hard runs.
