I have my truck in the shop as we speak getting some work done to it and one of the things they recommended was a $175 dollar fuel system cleaning. I am always wary of these types of things and wanted to ask if anybody thought it was worth it? Truck has almost 100,000 miles, I don't mind spending the money if it is something that takes a professional mechanic to do and was worth it but wanted to check first. Is this something I could do myself?

Thanks!

Does it run fine?

If yes then say no. Go to walmart get a can of seafoam. Wait till tank is low then dump it in fill up and drive like normal. You just got a fuel system cleaner. I do this every time I change my oil and have never needed to service the fuel system on any vehicle I have (other than changing the fuel filter)

the only thing i would rcm is make sure the throttle body is clean!! other than that, theres lots of stuff you can add to the tank and do the same job

Listen to the guys above.

My 2004 Silverado just started running rough for the first time in 6 years. Turned out it was the throttle body. $5 can of throttle body cleaner and a new $6 gasket and I was back in business. Clean the throttle body and use fuel injector cleaner every few tanks and you'll have as clean of a fuel system as can be reasonably expected.

I use Berryman B-12. Works as good as Seafoam but cheaper.

B-12 cuts the carbon buildup alot better in my opinion

A "Fuel System Cleaning" for 175 is nuts. I'm a mechanic and run a shop, I wouldn't be able to sleep at night charging that. The above post are correct.

Thanks for the advice, I was a little surprised at that price as well.
