I know, I know, but Lucas UCL really quiets down my fuel pump and injectors in my Silverado and it’s cheap. What about adding it to our 2.0L Volvo with a supercharger and a turbocharger? It’s really a noisy little engine (injectors and fuel pump). I’ve never had a turbo before, and don’t want to hurt it if I can help it. It does get 93 octane every fill up and top tier, so I’m not worried about the cleaning, just the lubricity.
