We are always running WOT in the 19' Starcraft. only a 800 Redstripe, I use the full synthetic like the smokeless attributes of it . I mix 16 oz to 10 Gallons & run Sunoco 93 Octane. Either Lucas or Penzoil. works good .
Running around the inland lakes have to get to where your going.
Out on the Great lakes we run 3/4 throttle. around 30mph.
