Toyota Repair: Seafoam

Question
I know a good service manager whom I asked his opinion of seafoam. He says its ok but says he prefers and performs for his engines a good old fashioned fuel system cleaning that shops do. Is seafoam not just as good ?

Thanks

Answer
Hello, I have never used seafoam but I have read reports from people that contact me tat it works very well, most of the "fuel system cleaning" that they do generally means running some chemical through the intake and putting a can of fuel system treatment in the gas tank, this does not actually clean the injectors. Try the seafaom for whatever reason and if there is still a problem it may be mechanical.
