Would putting in premium gas in my Integra...

[Syringer]

do anything to help me out during my smog check? That's what my friend told me..but since it's a Honda and is suggested to use regular, it won't help would it?

What octane does your Intergra require?

 

[isekii]

doesn't the GS-R require premium ?

Putting in premium gasoline and warming the engine up thoroughly, like running up and down the freeway for about 20 minutes, will help immensely in passing the smog test.

No it won't. If your car doesn't require premium it could actually hurt you in a smog check.

WRONG.

Using Prem. in a car not made for it will actually sometimes raise particles and make you fail. Yes having the car warmed up is good, but use the gas that is called for.

I will take the advice of people who run "check only" smog stations. They have all advised me to run premium gas for the smog check. They have nothing to gain since they are prohibited by law from doing repairs. This is CA.

I think it's because higher octane gas burns slower so if you use higher than required, not all the fuel is burned before the engine starts pushing it out the exhaust.

Though it depends on the car. Some toyota 1zzfe motors (like in my sig), supposedly advances timing when it detects higher octane fuel (atleast for 1zz powered mr2 spyder). If that's the case, you should get a complete burn either way.

This may be true, but how would this affect smog testing??

Burns cleaner.

edit: Happy, I've been told the same thing by mechanic(s) and the both the E-Test stations I've had to deal with... (e-test = smog).

Other things that will help... Oil Filter/Oil Change, cleaned air filter.. etc.

Any more views?

higher octane gas burns faster, smaller hydrocarbon strings make for the higher octane rating

 

[Syringer]

Anyone know of any verified sources that tells me whether or not I should do this?

 

[Bulldozer]

Higher octane means higher resistance to detonation. It does not burn cleaner. I see no reason why premium fuel would increase chances of passing smog tests.

I have had instances where I was running premium and, after learning about fuel, went with the recommended fuel (87 octane) and experienced improved engine performance.

 

[brtspears2]

I know my local smog check only station asks if you put premium fuel and drove it for 15-20 minutes before a smog test, since they want you to pass.

My friend's '90 MX-6 passed with this advice, but it accelerated like crap until he had chance to refuel with regular 87 octane.
