Fuel system cleaner?

[black90lx]

What is the best stuff out? I thought about using the sea foam. My jeep has went from 14mpg down to 12mpg.

let the motor suck out 1/3 of the can of seafoam. Shut it off for 5-10 minutes, then start it up, hold it at 2K until the smoke stops, then pour the rest of the seafoam in your tank.

Should improve.

do you mean pour1/3 in the intake them pour the rest in tank?

No, take off your brake booster hose at the booster check valve and get a bendy straw, let the engine slowly suck the Seafoam out of the straw. You dont want to let it suck a ton of it at once or you will kill it, let it suck it out steady until a 1/3 of the can is gone.

Oh, and hold on to the straw... you don't want that in your PCV system :lol:

In fact, time for me to do it on my GT too!

and... maybe my new Cobra-powered Lincoln :evilgrin:
