that site is great!

Black Yaris · 04-05-2007, 09:57 PM

who will be the first to have a jet propelled Yaris? Anyone live near that guy?

What the **** is up with people saying it is dangerous to go higher with octane? The manual gives you the LOWEST octane rating the car will run on. The higher the number, the better. There is no damage from going to a higher octane level - you are just putting in purer fuel.

wrong- higher octane has more additives

Octane is not a measurement of caloric content or burn-ability (cetane). It is a measurement of how high a temperature is needed in order to ignite the fuel. This is why premium fuel is usually only required on high performance engines (because they run at higher compression levels which generates more heat).

Higher octane fuel is actually less pure because of the extra additives which are used to make the fuel ignite at a higher temperature. These additives are also why it costs more.

Running fuel of an octane higher than what your engine is designed for can help with knock (detonation) but that is generally where the benefits stop. The detriments are:

- Fouled spark plugs due to the deposits left via incomplete burning.
- Greatly increased emissions due to incomplete burning.
- Fouled O2 sensors due to these emissions.
- Fouled catalytic converter due to these emissions.

Stick to what your engine is rated for. The 1NZ-FE engine in the Yaris is designed for 87 octane gasoline.

Little bit of the subject but that is why all the early RX7's should run the least octane in the Wankel...slow burn and doesn't promote the carbon buildup problem the rotarys have. Thanks for refreshing my memories on the rotarys Bailout!

But I still believe the computer compensates to allow 87 octane when used....but a higher octane allows the computer to benifit from the 10.5: compression....

Actually, that is my last car... and it was baller.

How many 5500 pound cars do you know that can yank a 14 second quarter mile with the heated leather seats on?

heh, that's one fast tank! hahaha

Sorry but you're living in the land of dillusion...using octane higher then 87 for your Yaris will give you WORSE milage....why is this so hard for you to understand? Using higher octane means the combustion is RETARDED, meaning that it takes MORE gas to give the car the same power....this means lower milage...the only exception to this is if the car is engineered (tuned) for higher octane....you keep thinking that ALL cars behave the same with higher octane...this is dillusion, or worse.

AMEN Broda!!!! You wrote it right and it is right!!!!! Why some here hold on to superstitions, urban myths, or what use to work with 1960ish cars is beyond me....

hahah, my sienna does a 0-60 in 7.4, and the 1/4 mile in 16.4. not too bad for any car, let alone a van that seats 7!! my van is probably a little slower than those numbers, since i gots all the goods, like power doors and trunk and heated leather everything, and i run only the required 87. those tests were done using premium fuel. but i can attest to the fact that i've beaten quite a few cars "off the line" using only the required 87...now if we can only cram my sienna v6 into the yaris...

ok Pavel, MR HIGH and MIGHTY.... you explain why it is that everyone that tries putting higher octane fuel in there Yaris gets better gas mileage? In the words of ChinoCharles "Don't you ever shut up?"
