tried octane booster this weekend... the one with the black horse on it. went up the mountains with three people and luggage in my car and a/c on. held 65 no problem. heat was fine car didn't sound like it was dying.
injector cleaners shouldn't be used... i've used them, they help a bit.
I always use the STP fuel system cleaner complete. You're only supposed to use it every 6000 miles or so, and I haven't used it for maybe 10,000. When I first got my car, 90 sentra, I was getting 25mpg, now I get around 36 since I've started using fuel cleaners. They can probably be harmfull if you use them extensively, but once in a while they can't hurt, especially on a car that is really old anyways.
Well what does a true fuel injector cleaning do differently than fuel additives. From what I understand most places just soak your fuel injectors in solvent which is all the fuel additives are, and they are 5 fold cheaper than a cleaning.

If you were to send your injectors to a place like RC Engineering, they would take your injectors apart, sonic clean them, reassemble them, flow test them, balance them (too make sure they are all flowing the same) and them send them back to you.

I know... just wanted to try it. It felt very good tho but feelings are feelings.
Also, using too high an octane level can cause your car too loose HP.

I think losing hp in that situation has something to do with the combustion occuring too slow because of the high octane, but not sure. Care to give a detailed explanation Subculture?
well barnoun... don't know what subculture will say... but MY logic is that since our car has a knock sensor and my ignition is advanced and I'm climbing up hill with the a/c on with three people in the car, the car will retard the timing at the first glimpse of any pinging/detonation which i know happens sometimes when going up hills regardless when the load on the engine is high... therefore the octane prevents that from happening and allows more power in the uphill climb....
It's reasonable in that situation. In a straight, or when detonation is unlikely though, I think you'd still lose a little power(because the timing might not be advanced enough to allow complete ignition of the slow burning high octane fuel).
