I was just wondering why the manual doesn't include this on the to-do list of maintenance duties for the S2000 (or for any Honda for that matter). Is this just an option or something that really should be done on a regular basis? Besides the fuel treatment, is there anything else that you guys think should have been on the maintenance list?

And if this is something that should be done regularly, what brands do you guys use on your S2000s? I perused the library under maintenance and saw something about fuel stabilizers - is this the same thing as fuel injection system treaters? If not, should both things be done? Thanks.

 

I believe it says in the manual not to use any additives at all.

 

I think they were referring to the engine oil, not anything you put into the gas tank.

 

Stabilizers are different than "treatments."

Fuel stabilizers help prevent the fuel from breaking down and harming your engine after sitting for a while.

"Treatments" claim to raise the octane rating or clean the fuel system etc, etc.

 

So I guess since the S2000 is my daily driver, I'll never need the fuel stabilizers, right?

Now about the fuel system treatments - is it good practice to run these through the fuel tanks once in awhile? These are designed to clean out the injectors and clean out the lines right? Someone correct me if I'm wrong.

 

Stabilizers: You're okay, with a daily driver the fuel is cycled through often enough to prevent stagnation.

Teatments: That's what they claim, but the actual results are questionable. For every guy who swears by 'em there's a guy who thinks they're "snake oil."

 

I throw one of those cheap bottles of injector cleaner into a full tank of gas at every oil change. STP, Wynn's - not real expensive and who knows, maybe it will keep the deposits down on the injector tips?
Another thing I do that the book doesn't mention is the treatment of all the rubber protective boots under the car. I liberally spray them with rubber safe silicone just before winter and at the end of winter. If you don't have 4 seasons, then once a year ought to do it.
There are 6 such boots - 2 accordian style ones on each of the front steering rods and 4 that cover the CV joints on the rear half shafts. This will ensure they don't dry out and crack. Once they crack, the grease falls out and you're looking at new CV joints.
They also give a fairly lengthy change interval for the tranny fluid. We all know that our drivetrain takes quite a beating and since the tranny fluid change is relatively cheap and easy to do, I do it annually.
The book also says very little about routine checking of the spark plugs. If people had never done this, we would have never found out before Honda told us that the plugs in the early year cars were coming loose and were not put in with the proper torque. I firmly believe that the spark plug recall was done as a result of Honda reading this forum and picked up on we, the owners found out FOR them. It's not a bad idea to keep track of your plug condition and tightness.
Vacuum out your air cleaner box.
