I would only use half of that bottle, if you can dump it into a measuring container. Run two tanks back to back. I find it did (does) a lot of good. Fuel economy while it's in the tank ( I know, nobody cares about MPG here) isn't that great and I do notice more carbon on the exhaust tips after those tanks; this could be the product burning off, or actual junk being expelled but either way, the car starts and feels better, especially in the cold.
