Default Seafoam - Any risks or all upside?

allroaders -

I am considering running some seafoam (or equivalent treatment) through my 2005 4.2l with 50k. (The car was a lease trade in, so I am assuming the original owner didn't run high test through it 100% of the time.)

I did some research on this site and it all looks like upside (improved hp, mpg, etc.) but wanted to check with the gurus before I commit.

Thanks for any and all feedback!

Default Seafoam is a fuel additive, like Techron

Here are the claims from the website...

Treats 3 Critical Areas: Gas Tank, Fuel Systems, and Crankcase

* Cleans fuel injectors
* Cleans carburetor jets
* Cleans carbon
* Stabilizes fuels
* Upper cylinder lube
* Removes moisture in fuel
* De-icer
* Frees sticky lifters
* Frees sticky rings
* Removes moisture in oil
* Cleans P.C.V. systems
* Cleans catalytic converter odors
* Oxygen sensor safe

I am not particularly familiar with Seafoam, but usually those thing are not that trustworthy (like 12 dollar chips that claim to boost your HP at 100+hps and reduce fuel consumption to half),.

Plus you cant measure the long run effect ( unless its been a while on the market) on Other parts.

Default Likely a waste of money. I'd go with 'Marvel Mystery Oil' instead, but you need neither!

Use a couple of tanks of Premium from a major, and you have done about the same. Moisture in the tank can be handled by keeping it closer to full. A long trip now and then will help dry the fuel, same with moisture in the oil.

An engine design / intake engineer from Detroit specializing in muscle cars suggested the Marvel Mystery to me. I've used a few times in cars over 150k ~ like chicken soup ~ it couldn't hurt.

Default I know many people that use it on their rovers

Not much discussion about using it on the audi that I remember though.

Default Seafoam can't hurt or Techron works...you can also Seafoam the intake manifold..

but will need to change plugs/oil since it gets alot of carbon deposits loosen. As with any fuel system cleaner you should run it one tank prior to oil change and even then run tank/fuel level to <1/4 to full effect

Nothing about defeating world hunger or global warming?
