Tom Chandler says Lucas Injector Cleaner Cured His Hard Start Condition on his 2005 Nissan Altima

My 2005 Nissan Altima had been running great until a few days ago when i was out and it didnt want to start...just cranked with no kick.. After a few minutes of cranking it finally started  but this hard start condition repearted.. I went to local auto parts where Lucas Injector cleaner was recommended.. After runnning about 5 hours on nthe highway with the cleaner, the engine smoothed out and my fuel mileage increased by about 10% over what I usually got.
