Shannon W. uses Lucas Octane Booster

The Lucas products are unbelievable! I keep my truck on the road all the time for work and with l over 160000 miles my truck runs like new with the use of Lucas products. I have always added the oil stabilizer at each oil change, the fuel system cleaner at each fill up, and now I decided to try the octane booster. WOW!!! I was a little sceptical at first about it but with the name Lucas on the bottle I decided to give it a try, boy am I glad I did. Don't get me wrong, I din't go from street truck to track truck overnight, but there was very noticable difference in performance. Thanks Lucas, keep up the good work!!
