Steve Garrett uses Lucas Fuel Treatment in 1993 cavalier 2.2 4 cylinder

I made a 311 mile trip, all highway, wrote down my milage, filled up, added 5 ounces of lucas. I called dealership with my VIN#, found out i have 15.2 gallon gas tank. I used half a tank of gas for 311 miles!!!!!! THIS WAS 41 MILES A GALLON!!!I don't even have overdrive. I paid $500 for my car 6 years ago, I tune it up every year, clean throttle body, new oxygen sensor, and been using lucas fuel treatment for a year and half. I now have 213,000 miles, and my car runs like a champ, no smoke at all!! My spark plugs are solid bright white from last year. I am sold on lucas. when i bought the car it was stuttering real bad, I used high octane gas and fuel injector cleaner, I am still on the same injectors. The girl i bought it off of, she is on her third car now. Steve Garrett
