How many miles should I drive before IC5 starts working? [SOLVED]

Thanks for the question, Anthony.

Here’s what I’d do: to get the most out of any Sea Foam fuel additive (whether it’s IC5 like you have or Sea Foam Motor Treatment), add it to a low tank of fuel and drive until almost empty before refueling. That way the treated fuel has time to work through the system.

Hope that helps!
