I apologize if this topic has been covered before:
The service department at the dealership where I purchased my 2012 Legacy just told me that there is carbon buildup on the fuel injectors, and they can clean them for $150. My Legacy only has 15,000 miles on it. Is this legitimate? I've read that the carbon buildup is normal, but should it need to be cleaned with such low miles on the car?
Can I get the same results if I put SeaFoam in the gas tank?
Any advice is greatly appreciated!
