I just brought my car in for an oil change. They stated it needed a throttle body chemical injection cleaning which I never heard of. I guess there is some carbon buildup on the air valve. Anyway, the price is $109.00 for this service. I did not get the servicea nd told them I would do it on the next oil change. The dealership states I am losing 2-3 MPG with this. Can I just change the air filter or put something in my fuel that will do the same thing?
