A friend of mine was taking his truck to have the gas tank cleaned out. His truck has over 300,000 miles. His fuel filter was dirty and needed to be replaced as well. I was following him to the garage so that I could take him back home. His car died on the way to the garage three times. The last time I took out my trusty bottle of Fuel Power and dumped three oz of Fuel Power in his tank. To make a long story short, his truck started right up and he was able to make it to the garage. He asked, "What the heck did you put in the tank?"
