I think the bottom line on the simple fuel system cleaner additives that are widely available, though, is to get Chevron's Concentrated Fuel System Cleaner. You can also use their Injector Cleaner if that's all that's available. Both have the same active ingredient (PEA), but the FSC is about twice as concentrated as the IC. The bottle of the concentrate stuff looks like: Chevron 65740 Techron Concentrate Plus Fuel System Cleaner - 20 oz. : Amazon.com : Automotive

There are other products that have good amounts of PEA. I think Redline's fuel treatment does as well, for instance. But the Techron's the one to remember because you can buy that just about anywhere, even a lot of gas stations.
