When to add IC5 to fuel [SOLVED]

Hi Joseph,

Thanks for the question!

Yes, you can add two bottles at a time.

However many bottles you use, here’s what I’d recommend:

Wait until your fuel tank is low before adding IC5 (5 gallons of fuel in the tank or less). The higher concentration will work better and faster than if you added it to a full tank of fuel. That’s the best way to use it.

Hope that helps!!
