high octane in a toyota corolla?

[theNEOone]

can someone out there point out any worthwhile reasons to put high octane gas in a '99 toyota corolla?

are you knocking?

You have too much money so you try to squander it any possible way that you can?

 

[TheBoyBlunder]

Money to burn, literally.

93 octane where?.....it's 87, 89, 91 here....higher octane =...? i suck w/ cars

 

[theNEOone]

hmm, well i always put regular gasoline (87) so i don't really pay attention to the higher ratings, but i could've sworn that it was 93. maybe i'm wrong.

Some places have 93 octane as premium. Some have 91. Depends on where you live.

Well unless you put in a really expensive race car engine in your car, 93-octane won't make any difference.

For your Corolla, if your engine pings a lot, i'd say maybe go with 89 but... yah 87 should be fine.

I think the difference between the octanes is that hte higher ones supposedly burn at a slightly higher temperature (someone correct me if i'm wrong). And b/c the Toyota Corolla's engine is set for 87 octane, you won't see any benefits by going to a higher octane. Just more money out of your pocket.

Waste of money to put high octain gas in a low compression engine. Octane does not equate to more power. The higher the octain the slower the burn in the cylinder.

Indeed.

Infact, you'll get less MPG with higher octane if your engine wasn't designed to use it.

Stick to whatever the manual says.

you need a higher ignition energy but the smaller hydrocarbons actually go faster.

No reason whatsoever ... unless you like to spend more money than you should.

One of the many links that will say the same thing.

what about those cars that say premium unleaded only. what happens if you use regular? for example, an acura 2.5 tl that i always have to fillup with premium.

big chance of detonation. which sounds bad because it is.

 

[TerryMathews]

Honda and Acura mean 91 octane when they say Premium. In reality, good quality 89 octane will work fine in most situations. Ran it for almost 2 years in my Prelude without any detonation or tripping of the knock sensor. Of course, YMMV.

To get the most power (and economy) from your car, you want to run the lowest octane you can that does not cause detonation or knocking.

 

[theNEOone]

well i'm not looking specifically to "increase gas mileage". i'm looking for ANY benefits.

terrymathews - what's "knocking"?

In older cars yes, newwer ones no. Newwer cars that call for prem. can run on mid octane and even low octane. You will lose a little bit of power, but if you don't rev it up a lot you prob can't tell. Newwer cars will retard the timing. My parnets z28 (ls1) call for prem. but a lot of their driving is on the highway so they use mid octane all the time.
