highest octane.

[Guest]

okay so i know there's 91 95 97 98 octane that gets sold at gas station.what is the highest ocatne that a street car can run on?iv heard a theory that all subarus get tuned on 100octane in japan,but no one has confirmed this yet,

so saftly what is the highest octane i could run in my car without risking anything?

cheers,any input will be appreciated

[DRFVDR]

AVgas is 110 this be good, never heard of any issues with to much octane,only to little

[Guest]

were abouts can you buy that from,heard off it before,but forgot lol.

is that safe to run in your car to?

[DRFVDR]

Airports/strips that run piston planes will have it

NOT LEGALLY ALLOWED TO RUN IT ON THE ROAD as it is not taxed at source

also kills Oxygen sensors dont it? - so theres an issue - and sometimes melts CATS iirc

Ive heard the ethonol blend sold at GULL is not suposed to be run on subarus at all? Why is this?

[DRFVDR]

Because the Ethanol eats the rubber hoses that Subaru use = Fuel leaks

i see.is it a mix or just drive if fill up with av gas and your away?

haha what they ont know wouldnt hurt them?

you are not allowed to pump it into your car...

must be a container/race car on a trailer etc and sometimes you have to sign for it/produce a Car Club membership

BP98 is fine... Av Gas is not worth it - dyno runs have proved it

[Guest]

yeh 98 is fine.but are the cars not tuned in japan for 100 %octane.im keen to give it a try.

your ECU learns the slightly lower octane.... self retarding

edit : a 'reset' is required to get the benefit.. there is a link around here to get the most power quickly out of a reset..

Also it's easy to smell if a car is running avgas. If you're pulled over and the cop takes a whiff of your exhaust, you're nicked. You can often even smell it if you're inside a car BEHIND a car running avgas.

Yes 'cos Avgas is full of lead.

Deadly to cats.

OP:

There's 100RON* octane in Jpn, it is called "super PLus" or something, and limited supplies of 102 in Europe.

*RON/MON different grades etc

vs

is also deadly

well after reading this im a little worried.

I put $50 of the E10 from gull (98ron+10%ethanol) into my beast to try out going to Taupo last weekend.

O.M.G.... I noticed the difference almost immediately, boost climbed faster and actually went past my normal boost cut off point (1bar) it also held boost better as it usually tapers off as the revs climb. she even had more nuts off boost.

I then put in $50 of the crap fuel I normally use for the trip back and what a let down now I think Im gonna replace the rubber sections of fuel hose and replace the injector o rings and anything else that needs doing so I can run E10 all the time. then Im ready for when E85 comes then it just a retune to make the most out of it.

hehehe I love more power.

I still don't believe that the NZ new cars from 1990 onwards had superior fuel hoses and o-rings etc over the JDM models for a fuel that hadn't been thought about for widespread usage. I have a feeling that its the typical bullshit to get you to buy an NZ new car rather than imported.

Still waiting on Gull to turn up in ChCh

[Guest]

cheers for the comments guys,i hear the new comapny thats taking over shell will be sell 98 gas also!ithink a gas station in nz shuld sell 100 102 octane for use subaru drivers lol

[Joker]

er you mean all JDM imports...
