So i'm pretty new to the turbo world and just finishing up my 08 twisted turbo. Long story short bought a wrecked m1000 with a twisted kit on it and threw the motor and turbo in my 09 chassis. Hopefully dropping the motor in this week and have 5 gallons on c16 i bought with the sled. I have read tons of posts on what fuel to run and still not real sure. Is higher octane almost a fail safe? I have no problem buying a drum of c16 or I read that sunoco 116 is good, but a little worried about the shelf life. The twisted I plan on running out west. Not sure where but high elevation. And I also have a m1200 big bore but cant remember what the guy said he ran for fuel. Depending on snow will be riding this one in the UP occasionally. Ill end this here and hopefully can get my questions answered. Any help is appreciated since I will hopefully be buying fuel soon.
