        Time will tell

        Our car seemed to be running just a little rough. I have just added this to a tankful of fuel, so time will tell. The reviews I’ve read and seen are positive, so I’m hopeful.

        1 2007 GT - KyleW

        Not again

        I thought this would be a good product put this in with a full tank of 93 and after about 1/4 tank used check engine light came on and started miss firing until I ran that tank out and now it's normal again will be sticking with Lucas or zmaxx

        My mustang prefers Lucas over Redline.

        I usually use Lucas, and the mustang loves it!.For some reason I couldn't even get the regular boost that I do with Lucas. I think I'll continue to use Lucas instead. Wanted to try it though and glad I did.

        Cheap solution for a common problem

        This product is so far the best I've ever tried on my car! The engine is smooth and the instant jump at low rpm is gone. (Highly recommended).

        5 2013 V6 - CamaroLOL

        Noticable Changes

        I wanted to wait a full 3,000 miles before sharing my experience with all of you. First thing is first, full exhaust, CAI, 93 tune. I notice that the throttle did become more sensitive. Hence, 0.2-0.4 MPG. I now get 9.5 city / 26.1 hwy. The reason for the HUGE gap is because I live in NYC, where there is traffic everywhere for 6 hours everyday and traffic lights every 50 meters. If I moderately step on the throttle (50), the tires will begin to spin out. Before it would take me at least 75 throttle. I haven’t had a chance to actually do 0-60s or 0-100s because of the weather, but for $12 and a 10 second “installation”, the return is pretty good. I’d recommend it to all of you.

        First time using Redline

        First time using Redline fuel system cleaner. I honestly can’t tell how well it’s worked bc I’m dealing with a lean bank 1 and lean bank 2 but once I get that fixed, I will add another bottle to the gas tank.

        As advertised

        Would've been a 5 star if not of the slow paid shipping. But this fuel cleaner surprisingly works well for my mustang. thank you :)
