Anyone have problems With BP Fuel? Knock Knock
My skis have had a history with a lot of knocking, Wondering if I should change fuel brands.
The BP station is right by the boat launch so I usually go there, but Maybe I should give another brand a try.
I've heard I should not need race gas or e85 till about 17+ PSI
My last ski ran a et137x4 wheel and was knocking a lot and now the new ski is knocking with just a stock x charger wheel. On a cold ride (43deg F out) it was knocking up a storm. I did have the timing a bit high but still 35 deg of timing and the cold weather should not have knocked that bad?
They only sell 91 octane here also and I know that doesn't help. Price per gallon is not a huge deal, If that station sold race fuel I would probably run it, but they don't.
Maybe I could locate some race fuel and mix it 50/50 with the 91?
I'm thinking if its knocking at around 12 psi this turbo I'm installing is going to make it worse, sure I can pull timing but that kills power so................
What are your thoughts?

Maybe its the nitrous?
I never fill up at the marina, always a servo with a decent turnover.

Over here Andy BP , Mobil and caltex 98octaine are probably the best . I never fill up on the water and try to use a high turnover servo .Imo you are going to go nuts worrying for the next few months as i said just send your ski over here

I wouldn't put ethanol fuel in my company car no matter how small % of ethanol . Maybe I need a honda engine in my kawa then I'd have then all covered .

In my Bmw X5 BP gasoline once you got sick, so q since I never use it again. I love Shell

Chances are BP did not make the fuel you are using. BP sold all their refineries in the US last year except for 3.
Higher octane fuel never hurts.

In Australia Shell high octane is the WORST fuel you could ever use in a ski or motorbike ..

gas gets shittier when it gets colder. Winter blends.
I always plop in Klotz or Torco just to cover my ass from any knock.
