is there a fuel additive/cleaner that everyone recommends?

[JDM Babaganoosh]

just need a decent fuel system cleaner.

[UnitedWeStance...]

Redline fuel injection cleaner. Never has let me down!

[BigMac]

Redline, Lucas, or Chevron TECHRON...

Lucas is readily available at Walmart and many other stores. A big bottle runs right around $10 at Walmart and treats 100 gallons of gas.

My '03 Cobra jumped from 13 mpg to 16 mpg after running a full bottle of the Lucas through 6 tanks.

[JSanders]

Seafoam is the only one that goes in my cars.

I work at a parts store so I got to answer that question a lot. The best I have used and the only ones I recommed is seafoam or lucas.

[cobrawannabe]

Seafoam or Lucas. I run Lucas twice per oil change and Seafoam every 15K.

[MikeD7]

Not to thread jack but has anyone used seafoam in their crank case or run it thru vac lines? I have used it in my tank and it works wonderfully
