How often should I use Sea Foam Spray in a Subaru GDI to keep valves clean? [SOLVED]
1 Answers
I have a direct injection Subaru, and I am interested in incorporating Sea Foam Spray as a regular prevention against intake carbon and oil buildup. How frequently should I perform the treatment to have valves maintained as clean as if I had a continuous port injection? I am thinking every 5k miles, but I have no scientific basis for this estimate. Comments?

Good question, Stephen.
For keeping valves clean like that, we recommend applying Sea Foam Spray twice per year. That will work well to clean and prevent buildup.
