Octan booster, Is it dangerous? Options

[Phr0z3n664]

I went and picked up some octane booster/fuel cleaner kit. I ran it w/ regular gas I noticed a slight difference in performance, it didn't hesitate throughout the gears, and got up to 60 slightly a bit quicker.

But my question is could this be harmful to my engine If I kept using it? my engine has 96,000 miles on it, and was only going to plan to use after every oil change.

So should I continue to use it or not?

QUOTE (GeEkBoY @ Jul 10, 2003 - 5:53 PM) The best way to boost octane is with ethanol, octane rating of 106 (I think, E-85 is 105).  Most other octane boosters are nasty compounds, ethanol is safer than gasoline.  Only issue is with high levels of ethanol is some vehicles have chemical problems with certain rubber coupmounds in the fuel lines and injectors.  Manufacturers allow up to 10% with no issues, so you could push it a little past that. if you add 10% ethanol to 87 octane fuel, you would get 87*.9+106*.1 = 88.9 if you add 20% ethanol to 87 octane fuel, you would get 87*.8+106*.2 = 90.8 If you want to make it yourself, check here: http://running_on_alcohol.tripod.com/ I see no point to running ethanol. Let me repeat... Higher octane WILL NOT enhance performance... What it WILL DO is retard detonation from occurring. The only time you ever want to use higher octane gas is if you start to notice pinging/knocking OR if you're running a higher compression engine. Thus 87 octane, which is what our engines were designed to run on, will suffice. It doesn't hurt to use 91+, but if you want to save some money, just stick to 87.

kuya is right about the 92 not enhancing performance 'cause i've tried putting a tank full of 91 octane in my celica ST to see if it would make a difference, but it didn't. It actually made the car go slower and my exhaust system sounded weaker like it was stock . I guess it's because the miss detonoation/combustion that was occuring when I had 91 octane in my car that made the exhaust system sound weak. The fuel cleaner is what you would use whenever you do an oil change like every 7k miles.
89 and 91 gasoline are for cars turbo and luxury cars. HERE'S A LINK YOU MIGHT FIND USEFUL: http://www.toyotacelicas.com/information/c...e/gasmyths.html
