OK I asked a few months back when I got the Superhawk about oil. I am currently running a Mobile 1 full synthetic. But it is a 10w-40. Not thick enough for the twin pumper in my opinion. anyone have any suggestions. I ask because as it gets hotter out I am hearing more motor noise than normal. I could be tuning my ears to it, but I think it is to thin on oil. It is also heating up faster in the mornings, as well. Another part of this would be, Do they make a 20w - 50 in Mobile 1 Full syn?
