How do I know if my fuel system really was cleaned?
 

I recently took my 07 Chrysler Pacifica in to have the fuel system cleaned, just part of regular maintenance. I was wondering though if there is a way to tell if the fuel system really was cleaned.

I had seen a TV news report about oil change/maintenance places that were being investigated for fraud. They were selling services like oil changes to people and then not performing them. So now I'm a little paranoid about these types of things...

Thanks!

There are a number of service of stations which perform this type of forgery with their customers, but if you take your car to a registered service station then it won’t even try to do this type activity with you. The reason behind this is that they have to build their prestige in front of their customers and these types of incidents are harmful for their future aspects.
