I added a bottle of 104 octane boost to a little over a half a tank of gas and I can REALLY feel the difference.

BTW: Your truck is set up to run 87 octane. Your doing quite a bit of damage. I am asuming you filled up with 93?

Furthermore, octane 104 will NOT boost your octane rating to 104! Thats what I've read. There is a way to properly boost it with another chemical. Not sure what it is.

Why again do you want to run 93/104?

87 octane fuel burns much faster and will provide a more complete burn! Much more volatile fuel!

Mlaugh,

What's the problem with octane boosters?

Thanks, fish

 

Believe it or not, 87 octane does burn better than higher octane fuels.

Anyone who has accidentally put unleaded fuel in a diesel engine will attest to that. KA-BOOM! Hehe.

 

Furthermore, most folks are of the opinion that higher octane means better fuel economy and performance. The mentality is that if racing cars use it, it must be good! Sounds logical, right? The truth is that racing cars optimize their compression ratio, which in turn, requires a fuel that is less volitile. The end result is they need higher octane fuel to prevent pre-ignition (engine knocking).

There is little to no difference in the amount of energy that 87 or 93 octane can provide. The BTU's per gallon are practically identical. The real power is in the engine's compression ratio! Increase the ratio, you'll increase the power. And of course, you'll also need to use a fuel that is less volitile!

This myth about high octane fuels being better was started way back when our parents were driving around in the klunkers. When the engines started knocking, you changed to premium gasoline. The more it costs, the better it must be, right? Not true. It'll get rid of the noise because it burns slower.

Uninformed people who use a higher grade of gasoline than specified in the manual are simply giving their money away.

There should be a story on 60 minutes about this!

 

ddt101,

Gasoline has a lower flashpoint than diesel. This is why it will pre-ignite in a diesel. Not the octane rating.

 

First off the brand of booster was 104, second it did help the "pinging" my truck was doing and third it helped my throttle response. The throttle response is what it REALLY helped the most. Just thought I would clear all that up.

ddt,

If folks didn't use the high octane stuff, then it would not stay fresh, because I have to use it in my BMW Motorcycle. So luckly some folks to use it.

The only reason it increased throttle response is because the knock sensor wasn't backing the timing way back. If you are getting real mild pinging under heavy load, w/hot ambiant temps, w/87 octane in a fairly stock truck, that is normal. Anything worse than that or having to go to extreme measures is a clear indication there is a problem with your vehicle. You need to fix the problem, not buy an additive to cover it up.

 

So what your saying is that a very small
percentage of vehicles need high octane.
why is it available at every station in the
free world? just so a few people can have
the fuel they need? I find that hard to believe. Wouldn't 93 provide more power
because it burns all the way through the
compression stroke? I am just asking
because I don't know,so don't be too harsh,Ok?,,,,,,,,,,98

OK, let me ask a question about this...

If I add a bottle of octane booster to a tankful of regular (87 octane) gasoline, will it work with my Superchip?

Actually, this is a question probably for Mike Troyer, so I'll also post it under computer chips forum.

But please, feel free to comment on this.

If you take an engine designed for 87 octane, I.E. 5.4l, and don't modify it at all, if everything is operating correct, by adding 93 octane you will see no increase in fuel milage or performance.
If you do see a change then there may be something wrong with your engine, causing the electronics to back off the timing, thus a decrease in power and mileage. Then when you put in the 93 octane the engine can go back to it's desired timing you think there is a big performance boost, but all you did was go back to where you should be!
There are vehicles that require higher octane fuels from the factory. F150 is not one of them.

98SCREAMER:

Stations offer higher octane for vehicles that require it. For instance, Z28, Mustang GT/SVO, Corvette, Maxima, Viper, etc... Those, and many other, vehicles have engines with high compression ratio's that require a slower burning fuel. Hence, 91 or greater ocatane ratings. These vehicles have an owners manual that provides information to back what I just said. Most tell you its ok to run 87 for emergency situations only!

My Honda CR-V has a 4 cyl engine that requires 89 or higher octane. I only use 89 because It's a complete waste of money to put 93 in. With 87 I get some knock.
-----------

WJT:

I would be willing to bet cash that adding one little bottle of 104 to my 30 gallons of 87 does not bring the rating up to 92 (required for Superchip). Furthermore, I'll bet it does NOTHING AT ALL!
I think I read somewhere saying that you would have to put 1 or 2 gallons of 104 in your tank for it to help.

Do a search, there must be more info on the site.
