I need help. I have used Amsoil Premix oils in the past with good results but I ran out and tried others (Motul 800, 927, Honda full syn.). I lug my 07ec300(250 with 300 top end) like a John Deere tractor and it spooges real bad. There was less smooge with the Amsoil oils than any of the others I've tried so I'm going back but I will use a different mix ratio. Before I mixed 43/1 (HP Injector, Dominator, Interceptor) but want to try 64/1 or 80/1 to help with the spooge problem. My jetting is 168MJ, 38pilot, CCK 2nd slot from top, #7 slide. I've tried 927 oil at 64/1 and the leaner oil mix richened up the fuel/air mixture so much that I foul a plug every time when starting it cold. Once running it will go all day without fouling.
So I'm looking for recommendations on which Amsoil oil, which ratio (64/1 or 80/1), and jetting. I'm leaning toward Amsoil Saber at 80/1 (it's formulated for 100/1 but Amsoil recommends 60/1 to 80/1 for more extreme conditions).
