Review on 🔥 Revitalize Your Fuel System with Red Line's Complete SI-1 Fuel System Cleaner - Gas and Injector Additive Treatment (12 Pack Case) by Jeremy Bradford

This is not snake oil for high mileage vehicles. Excellent stuff. If your car is running sluggish and/or pinging, this will correct the situation. I put Red Line Fuel System Cleaner in my 2011 160,000 mile Prius, which made a chirping noise when accelerating from a standstill while under heavy load from the engine and A/C compressor (hot California summer). no more noise He also fixed a sluggish 2008 Nissan Versa with 90,000 miles on it. I dumped it into a nearly empty fuel tank before refilling premium with Techron or a similar cleaner and let the car run a little harder than normal for 10 minutes. I've been using my regular kind of throttle since with no problems with acceleration or ringing. Update: Fixed throttle response on my 2008 Lexus with 215,000 miles. It works like new again.
