Default 92 or 94 octane for WRX?

Is there really a difference in the 2 gasses??? besides the price??


is your car more responsive when you put 94 + octane in??


I've had my WRX for 4 months now, and always used 92, but now my friends are debating me that Turbo charged cars need 94...

BTW: who's WRX did i park beside at the eaton center parking lot on sunday???

I only have 2700 kms on right now, I have used 92 the whole way through. I used 94 twice, when it was cheap. I did not feel a difference. Seemed to get a little better mileage though.

What color WRX? was at ET?

If it was white, slammed with pink banners, it was Orbiter.

94 will have less detonation than 92 and is supposed to be good for any car....just depends on if you really need it and is power enough to ignite the better fuel?!

maybe u are not driving ur car hard enough? or maybe it is too good to feel that 2 octane diff? but u will notice that when the car gets older or when u are pushing the car uphill....pretty minor diff though....yet it's better....cause less carbon deposit too....(in long term)

only $3 diff for every 100L? so each tank maybe $1.5 more? unless u drive a LOT everyday or else i will say it won't cost u too much more for every month???

just my $0.02....

Yeah, that's about right.

To really answer this question you need a scantool to check the ignition retard being used with 92 and 94 octane. But with my seat of the pants observations, here is what I found...

No difference between 92 and 94 in typical BC weather (today is the hottest it's been since I moved up here). In California, it's a different story. 27+ degrees, stop and go traffic (so the intercooler gets heat soaked), 91 octane (recently reduced because they added more oxygenates) ... the car was pinging like a mutha. Up here, we have better gas and better weather, so there should not be detonation problems.

This is with Chevron BTW.

Of course, if you are running an MBC or other trick items, then all of this is moot.

As a footnote, I was told by a PCA member who watched a presentation on gasoline from a "gasoline expert" the following: always use the lowest octane your car is happy with, because it contains less additives. 89 octane is actually the best in terms of clean burning. I don't know how true this is, but food for thought...

sometimes i do think diff between 92 and 94 isn't that big....

i am using 92 on my Civic now as well as Joyce's RS....really couldn't tell the diff between 92 and 94 (i am not sure about WRX but my dad's Volvo 850 Turbo 94 is better....we can notice the diff)....

i tried to use 89 but after just half tank or so i pumped some 94 in to stop the annoying pinging when i go uphill....high rpm driving....

for low end....i think i notice slightly better torque? dunno if it's true but i just think w/ my kinda driving and mod i have i have to use 92 on a Civic....so WRX should use even better? especially if u are modifying it quite a bit....u can't run away from higher octane and u will wish u have even higher octane available...

i am up to 7000km with my WRX now and i 've always used 94
94 would be a very very expensive gas for WRX if you are a high reving person.
but if you drive smooth with a WRX it would cost less giving you the response you'd expect for driving smooth anyways.....

Conclusion: 94 betta for those who drive smooth with WRX
92 betta for high revers.


cost wise that was my report...
Performance wise, for a WRX you won't really know the difference between the two since the car response so heavily with outcome that is good enough to beat even a porsche with either of the gases..

Stick with what's recommended in the owner's manual people.

Unless you are pinging there is no need for higher octane gas. As well, unless you're sufficiently well modded you have no need for higher octane gas than what is recommended in the manual.

Unless of course you're running much higher boost, etc...you'll just be wasting the money.

Ya right...
And while you're at it, do the other stuff they recommend in the manual: replace the tires with the same size/brand/model as stock.....different sized rims are not recommended....don't bother using syntetic oil once the car is broken in.....don't do 'jackrabbit starts'.....don't bother letting the turbo cool down before switching the engine off....USE ONLY GENUINE SUBARU PARTS!....etc....

Yes, it will ping for a while until the ECU retards timing sufficiently to stop the ping.

On a new engine, by that time the rings will be blown to hell.

You can bet I made sure my dealer filled the new car with premium.

You guys suck!

At least you have a choice! Down here in the US, many of us have to deal with Premium gas limited to just 91 octane!

Default <-- one for me, one for the car</homer>

I heard the only *real* difference between the two, besides price, is the higher the octane the better the your mileage is.

What is cool about canada, is in the winter mohawk has a 94 winter blend, which contains a little bit of ethenol.

Don't use too much Mohawk gas.. Too much ethenol is bad for the engine! I know my mom's camary manual said something about try not to use too much ethenol gas..
