How much Sea Foam in 2013 Buick Enclave [SOLVED]

Thanks for the question, Donta!

For your Enclave (or any vehicle), add at least 2 oz of Sea Foam per gallon of fuel in the tank.

Here’s what I like to do: add a full can to a low tank of fuel (1/4-1/8 of a tank) and drive for at least 20 miles before refueling. That creates a high cleaning concentration of Sea Foam and gives it time to clean. It’s one of the best and most efficient ways to use it!
