If you’re a car owner in the United States, you know that fixing your car running rich is a top priority. But if you’re not sure how to fix it, or you don’t have the time or resources to do it yourself, there are a few things that you can do to help. One way to fix your car running rich is to change the oil. A new oil will help improve your engine’s performance and prevent it from breaking down. You can also try changing the air filter and radiator cap, as well as adding a fuel filter. If all of these steps don’t work or you feel like your car is still running rich, then you may need to take it in for an inspection. An inspector will be able to tell you if there are any problems with your engine or drivetrain, and they may be able to recommend other ways to fix it.
