Kent uses Lucs fuel Treatment

I wanted to take a moment to tell you what my family thinks about your Lucas Gas Treatment.

In march my daughter layne had her science fair. my husband Kent, was going on a wild hog hunt in texas around the same time. So he suggested Layne do her project on gas treatments. the treatments were Lucas, stp and parts plus.

Needless to say Lucas did the best. Kent went from 16.3 to 17.8 per gallon. Kent tells everyone about Lucas. We know 5 people using it now.We have 3 vehicles and use Lucas in all of them. We are even buying it in the big economy bottles, Thank you for making such a great product. We would not have known how good it was if Kent hadn't of taken that trip. He came back with no wild hog but one customer sold on Lucas. Layne made a 95 on her report or was it Kent that made the 95.

Thank you again
