yeah depends on the compresion ratio. no matter what cc size as long as u stay under 11:1 u should be fine with pump gas. but once u get around 11:1, i would, start to think about at least mixin 50/50 race gas and pump gas. better safe than sorry.

Ummm i am kind of in the dark when it comes to the ratio to use. Umm what ratio should i use?:confused: Sorry bought this.

i can run premium plus(92-93) octane in my 300(11:1) and it won't have the gas knocks, but it is better to mix it half and half (110-93)
