I have a 2007 Toyota Corolla with less than 20,000 miles. At a recent oil change the Toyota service department said I needed an Induction Service at $90 and a Fuel Injection cleaning at $100. I've always been told these were scam items for auto repair shops. They pour $3 worth of some chemical in your gas tank and charge you $190. My last car was a Nissan Sentra I bought new and put 160,000 miles on without these services. (I also know the person I sold it to drive it for 4 more years). One other point, I overheard the same pitch to another customer when I first checked in. Seems to me they are trying to make revenue in service because the economic downturn has hurt their car sales.
Is this service a scam?
Does a car with less than 20,000 miles and running perfectly need this service?
Is there any scientific data proving this service extend the life of the car?
