I'm not one to jump on any band wagon for “get better products for cars” but Lucas produces one heck of a product. As I put more miles on my car it appeared that it started running rough and was getting poor gas mileage, after you gave me a few bottles of Lucas I thought why not try it, it sure can't hurt? Well my Volvo V70 T-5 all of a sudden started to run smoother and also started to get better mileage. I decided that maybeI should start using it in my wifes 2000 Mitsubishi Eclipse GT well as you know the GT is a High Performance car and yes it became a High performance car again.
