I'm sure alot of people has ask this question, but I don't know so I going to ask it. Is it okay to run 101 or 105 octane on a stock motor with a 100 or 125 shot of nitrous. Or do I need to run 93 and mix in 2 or 3 gallans of the 100 or 105 with the 93?

 

If your seeing alittle knock, it'll be fine to mix in some 100 or 104. If your not detonating on 93-94 then there is really no reason to run 100 or 105. With stock timing you should easily be able to run a 100-125 shot on pump gas.

 

Just make sure that fuel is UNLEADED, or goodbye to your O2's!

 

As long as it's unleaded fuel, it's not going to hurt anything except your wallet.
