Fuel system additives? Options

[D-Man]

Okay, it seems that people are putting all kinds of stuff into their fuel systems to clear out all the unwanted material, and to improve MPG.

I've been hearing of Sea-Foam, Lucas Oil, and Various other detergents/cleaners. I wanna get this ball rolling so we can figure out what is indeed best for our systems.

So, What are ya'lls opinions?

Personally, i use a detergent based injector cleaner every few months or so, not that it causes a big difference, but i like to think that that 6-7 bucks keeps my injectors clean so that i wont have to notice a big difference, and prevent problems before they occur.

The engine sputters while the Seafoam is going through the intake.
ANY engine cleaner that is run through the intake will effect run quality during and for a short time afterwards, you're taking O2 from the intake stream and adding something else [plus the crap that is broken free], it stands to reason it's not going to run right.

Once it has ran through the engine should run as good or better than before.

Depending how dirty your engine is inside, you might want to change your plugs afterwards.
If you're running platinum/iridium I would suggest you buy a cheap set of coppers to waste while you clean the engine.

I tried Seafoam last weekend and I can say for $8, it's the single cheapest way to increase performance. Engine runs much smoother, especially when you are accelerating on the freeway, or taking your foot off the gas. I plan to use it every 2500 miles or so. It's a huge improvement when you have a high-mileage engine (I'm at 128K).

That's assuming the inside of your engine is really dirty.
If you do it again in 2500 miles you're not going to see much of a change [unless it didn't clean out most of it the first time].

Good stuff, but only works if there's something to clean.
