I use your fuel injector cleaner and oil additive in all of my cars. After running the engine for a short time after putting your product in the engine I notice a huge difference in smoothness of idle, throttle response and overall improved performance through the entire RPM range while driving. I put fuel injector cleaner in my tank every 2-3 fill ups and notice a differnce if I forget and let it go longer between treatments. I normally do not use additives but after using the Lucas oil products, I couldnt go back to suffering with a stumbling idle or sluggish response for anything.

Thank you for making an excellent product that I feel will lengthen the lifetime of my vehicle's engine and make the time I am driving it more enjoyable.
