Dwaine Walters Is Spreading The Word About The Lucas Fuel Treatment

I have a 98 chevy 1/2 ton truck I bought used for work. On long hills it would start missing and the engine light would come on. I started using your injector cleaner and my gas mileage immediately went up almost 2 mpg and after a few thousands miles I have no miss or power loss on the hills like before. Saved me having to pull it apart and replace injectors, great product and we use it in all our cars. Thanks for sponsoring short course off road racing and all you do to help out motorsports..good job. I will continue to spread the word on the injector cleaner.
