Review title: The car won't start after using it
Product review: I've put the whole bottle into the gas tank as the instruction said. The car drives OK at the beginning and the MPG does seem to improve. But later I notice that I have problem to start the car. At the beginning it won't start at the first time but will start after several tries. After 3 days the car dies completely. I can't no longer start it.The customer service said I've put more than recommended volume into the gas tank. I don't know if it is the problem. Be cautious if you want a try.
