I needed to replace a very dirty air filter on my Jeep Grand Cherokee after buying it used. My gas mileage has tripled and I no longer have an engine light warning. Considering that the original EPA mileage rating was 16 mpg, and I'm getting 18 combined highway/city (about 21 highway), this was a great investment.
