Thanks for the question, Cararino!

Either one will work – just depends on what you’re looking for!

IC5 is formulated just to clean fuel injectors in gasoline engines.

High Mileage Motor Treatment cleans the entire fuel system (fuel injectors, passageways, chamber deposits – anywhere fuel reaches in an engine). It’s formulated to help older engines run smoother and last longer (it’s strong!).

For what it’s worth, High Mileage is a great workhorse for an engine like your Monte Carlo’s. Add a full can to a low tank of fuel (1/8 of a tank or so) and drive for at least 20 miles before refueling.

Here’s a helpful article if you want a little more info about the differences between products:

Hope that helps!
