HOW TO: SEAFOAM (Motor Treatment) A 370z

Bob is the Oil Guy . Be warned: if you're at all sciency/nerdy and into cars, clicking that link could cost you weeks of time while you get sucked into it

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.

Thank you sir, I will be on the lookout for this.

Is it a once/twice a year sort of thing, or every fill up?

Beats me. I could say "depends on your conditions and habits", but honestly even if I knew those things, I don't have a fact-based answer for you. I definitely don't use anything in the fuel more often than once every few months, sometimes it's closer to a year.

I haven't done it to the Z in quite a long time now... but in place of that, roughly every 2nd or 3rd track weekend or so, I put a half tank of unleaded race fuel in the car, 98-octane Sunoco 260 GTX is usually what's available at a track pump. I figure that and the hard driving on a hot engine keeps things pretty pristine in there. It's normal street-driving conditions that gunk things up more.
