Sea Foam in 1985 Pontiac Firebird [SOLVED] Asked by Michael K. In Manitoba, I have a 1985 Pontiac Firebird V6 with premium gas in the tank. what is the best method to use Sea Foam Motor Treatment?
Thanks for the question, Michael.
Additionally, a Sea Foam Spray treatment every 3,000 miles or so is a great way to keep your Firebird running strong.
Hope that helps!
