Higher octane gas does not detonate as quickly, so you will get better mileage. If you want to get the most HP, stick with what your engine was designed for.

 

I only put 100 octane in my accord, but that's cause I'm always running it on NOS, and drive my civic daily.

 

Does the AV6 really go 0-60 in 8 sec? If that's true then that's only a fraction of a second quicker than my 4 bangin auto.

Anyways, stick with the regular gas/help your ride/keep your performance/and be kind to your wallet.

 

damn n2o refills and 92+ octane is raping my wallet

 

I only put 92+octane when temp. here goes over 98 degrees. Higher octane will burn at higher temp. but usually I put 87 octane and every oil change i add the injector cleaner fuel treatment.

I dont know works for me

 

Must just be me who runs 98.1 then.

 

 

Why? :dunno:

:bs:

Okay I guess I was not clear.
When the temp. gets hot around 98-108degrees you should use high octane (91+ or what ever grade) because it will make you engine even hotter than normal your radiator will cool your engine but hot does the radiator work it take the passing air to cool the coolant down. Your engine is made of aluminum alloy which can gain and lose heat quickly but if temptures is freaken Hot like durring the Summer time your car will likely ping more often.
People talk about PING in their car which is likely due to early combustion.
HIGH OCTANE will ignite at a high tempters, so when the tempters goes over 98 degree (summertime) I use 91+ octane.
THE END

Incorrect. Higher octane fuel alone will NOT cause your engine to run/burn hotter. People say this, but they're wrong. It's the higher compression ratio that makes the burn hotter. The higher octane levels are necessary on these engines to prevent pinging, but only because they have a high compression ratio. Accord engines have LOW compression ratios that simply DO NOT require high octane fuel.

I don't even know WTF you're trying to say because you can't even put a sentence together. Radiator?? :dunno:

Okay, if you have pinging in your engine in the summer and have to use higher octane fuel, that's because there is something WRONG with your engine. Such as carbon deposits and hot spots. This can happen in older engines and in fact cause you to have to use higher octane fuel even if the engine was designed for a lower octane. But then using a higher octane fuel just sweeps the problem under the rug. The REAL problem is still there, which is deposit build-up in your engine.

Hey guess what...

There is a good argument that using high octane fuel in an engine not designed for it can lead to deposit build ups. Higher octane fuel is more difficult to burn and requires a higher compression ratio / hotter combustion temps to burn efficiently. So if you put premium in a LOW compression engine like an Accord, there's a chance that you are HARMING the engine with the higher octane fuel that isn't burning as completely as it should. Of course, the damage wouldn't show up for a VERY long time, but there is a chance you are in fact doing damage to the engine.
