Brian Lucas uses Lucas Fuel Treatment in 2001 Ford Crown Victoria

I am a State Trooper in Florida. I have a 2001 Ford Crown Victoria that I patrol the interstates with. My Vehicle has 90,000 miles and probably the same amount just idling. As my vehicle accumulated more miles, I didn't have the acceleration or the top end compared to when I got the vehicle brand new. Someone suggested to me to get some Lucas Fuel Treatment and use it with a full tank of gas. I filled up twice and added the fuel treatment each time. It was not long before I noticed the difference when I caught up to a speeding motorist. I had a lot more horsepower during acceleration and I gained 10 more miles per hour on the top end (incredible). I was very impressed, almost astonished with the product's performance. I have never gained 10 more miles per hour on the top end with any other type of fuel treatment or specialty product and would have never expected those types of results until I used Lucas Fuel Treatment and that is not even mentioning the better fuel mileage I'm getting. Now a majority of the other Troopers in the district are using the Lucas Fuel Treatment regularly in their vehicles and getting the same results that I did. We also use Lucas Fuel Treatment in our personal vehicles after the results we've seen. It's nice to know there is a product on the market that really works and can restore life to a vehicle that is tortured daily. It's obvious that Lucas Oil has set the standard with their products. Thank You Lucas Oil for helping myself and others perform our jobs and keep the roadways safe.
