School me on fuels please. . .

[TSITurbo95]

Ok, so I am having a hell of a time getting rid of this knock on my setup. Anymore timing adjustment and I won't have any at all. So I was throwing around the idea of switching to Sunoco 100 octane. Any thoughts on this? Is it more/less knock prone?

Not a fan of the e85 goo goblin, so I am trying to stay away from that, as well as there is not a station close by.

Any insight is appreciated.

I've used Sunoco 113 before, I actually still run that in my motorcycle. Sunoco makes some great fuels! I prefer VP, but Sunoco is easier to obtain. Where I live at least.
