Decarbonizing Fuel Injection Service | Mission Muffler & Brake

Mission Muffler & Brake offers an amazing service called a decarbonizing fuel injection service. This service should be performed every 15,000 miles.

What does this service do for a car? It mainly does two things for a vehicle – increase fuel efficiency and power of the vehicle. The service does this by removing the carbon that has built up in an engine. An added bonus that a decarbonizing fuel injection service can provide is to help pass a smog check. Some vehicles that have failed a smog check will only need this service in order to pass the smog check because it reduces the amount of carbon that is produced by the engine.

Mission Muffler & Brake tries to save the customer as much money as possible and this is another example of that. Rather than having to perform a costly catalytic converter replacement, they perform this maintenance service to help a vehicle pass a smog check.
