Octane boost

I went to the store today on my break to look at the boosters they have out there and I knew there are a lot of diff brands out there. I saw NOS, Gold Eagle, Lead Supreme, STP, OutLaw and the list goes on. I have used NOS, STP, and OutLaw before and would like to know if anyone else has used it and if so, what brand do you use and what is the best kind to use???

Never used the stuff, but unless your bike is timed for the higher octane you're wasting the cash...just send it my way instead!

I have never used it in my 750 I have now. It is not timed higher that I know of. Just wanting to know what everyone thought of it. And thanks for the offer but I think i will keep the money.

Yeah, what I'm saying is that it's a waste of your money. Just like 93 in your escort or whatever. If it's not designed for it, it's a waste. I'm sure Larry will back me up on this!

I've heard it's actually harmful to your fuel system, primarily fuel lines.

Hey Chris and Shan thanks for the info on it. I always use 93 or 94 in it and didnt know if it was a good thing or a bad thing to add the booster in it as well so thanks for leting me know. I might have to try that 93 in the escort thing.

What about like fuel additives that are cleaners - like fuel injecter cleaner to clean your fuel system and remove carbon deposits, etc.?

Fuel cleaners are nice. I generally put a bottle in my cars like every oil change. But nothing beats changing your fuel filter. One of the top portians of cleaners is eythonal. Which is in most of your gasoline anyway. It is basically a gas achohol mixture. What is achohol good for??? Any kiddies know??? Cleaning!!

In my neck of the woods not all gas comes with eythonal. When the semi trucks haul load after load after load of this gas with no eythonal in it. The inside of the stainless steel trailers gets a bit dull. Then when they haul a load of gas with the eythonal the trailer comes back all shiny on the inside from the splish splash of driving down the road. Just as achohol would!

You'll hear some of the old timers saying that the first time they ran that in their cars messed up the fuel filter and stuff. That was cause it cleaned all the crap out of the tank and lines and clogged up the filter.....

Any more questions...

Chill dude, I only get to get here in the evenings :P

Anyway, my take on octane booster is...WHY?

First of all, octane is a fuel's ability to resist detonation. There is no advantage to running a fuel with more octane than what your engine requires. In fact, it could be argued that excessive octane makes it harder for the flame front to spread and therefore your engine loses efficiency with too much octane.

If you have an engine that requires additional octane (usually from more compression), you should be running a race gas. If you are out on the open road and race gas is not readily available, running octane booster is better than nothing. However, I wouldn't recommend racing it that way because you don't really know what octane you are running.

Now, on turbo applications (such as my car), having higher octane is an advantage because I can run more boost and/or more ignition timing. In fact, I can have multiple bost/timing/fuel maps. Whereas most bikes maintain a steady amount of compression and timing, boost and timing changes directly affect how much octane is required. However, I am still better off using race gas so I get a consistant fuel mixture and not the random results of pouring a botttle of stuff in the tank.

HTH,
Larry

Rarely is the question stupid, but sometimes the answer is you need to run everything you read online through your own personal BS meter to determine if it makes sense to you.

The other thing ethanol or other alchohols are good for is absorbing water. Water does not mix with gasoline, they will separate in a container. This is how the winter additives work, the alchohol mixes with the water and draws it through the fuel system. That way you don't have pockets of water that will freeze easily and block fuel flow.
