Rick Johnson uses Lucas Fuel Treatment

My 1997 Pontiac star ted running really bad and the check engine light came on so i put new spark plugs and replaced the fuel pressure regulator which didn't help. I spennt $75.00 for nothing. My brother inlaw told me about your fuel additive so i tried some in 1 tankfull and within 2 days my car was running great and the check engine light went off. I'm sold on your product.
