100% Octain Containing 10% Ethanol

[fly333]

Hi was in united petrol station and noticed 100octain containing 10% ethanol for 5c less then 98ron..

Is this okay to use in my r33 Gts-t ser2? Everyone has their own ideas on this so would like to know facts if anyone knows anything good or bad about 100octain containing 10% ethanol.

the old shell vpower racing 100octane from shell was 5% ethanol and it was fine in the skyline

you gained zero power but you gained a bucket load of resistance to detonation/knocking

10% ethanol might be a different story and may be enough to alter the AFRs enough that it could be unsafe etc, best to have a workshop who has worked with ethanol comment before using it

Not so much power gain but as mentioned, better resilience when your engine is under stress.When it was availbale in my area at Shell, I always filled up on it and never had a problem.

i was recomended from my mechanic to that....its meant to be better...but still for some reason i dun always fill tht since the car was tuned when it had 98 from bp and there are only 5 or so of them tht have that fuel in victoria...but whenever i filled it with tht from united, my car didn knock as much (coming from the readings from the hand controller) and didn feel a difference...

so in my opinion it shud be fine...only got benifits out of it when i filled it...less expensive and less knock....

Been running that for about 4 months in my car now...was tuned on that and while there wasn't a noticeable power gain (couple of kw) there was a noticeable drop in knock readings on the PFC across the board...if anything the added detonation resistance is a plus...i don't even bother to run octane booster at events now...

[itshimdazza]

have you guys got the addresses of these united petrol stations?

I am curious to try this

Used the mulgrave one on a few occasions and the bayswater one i used every week as i pass it on the way to work...

Hi i spoke to head office of United and i asked if it was okay to use 100octain in my r33 gts-t and he advised me to contact Nissan and ask them..hmmm

After speaking to Nissan they advised me that Nissan are against using fuel containing ethanol...and so ill be sticking with 98ron until i find out more.

[limpus]

Thats what they always say...so many of us have been using it for so long with no issues...people are even using E85 with no issues (but that one needs a proper retune with supporting mods)...nissan locally don't always give the right info anyway...

[fly333]

Okay so your saying 100octain is okay to use but if i used E85 ill need to get my car tuned?

Read up on all the info on E85 here...i won't go into the details...to run E85 you will need a fuel system capable of supporting it and a tune to match...E10 is just for detonation resistance...

[fly333]

Do you run 100octain from united in your car? have you noticed any power gains and do you get less or more km out of a tank.

Dude read the following replys in this thread

Think ur question was answered already...

its safe to use without having to tune the car on it...other than getting less knock (positive point) no other issues have been noticed...

so when u feel comfortable, try it....

Cheers

cheers to all will be giving it a try today

I tried it in my previous turbo car and noticed consistenly worse fuel consumption. This was without getting a custom tune with the fuel of course. About 5L/100km worse.

Noone seems to mention there fuel economy on it but you guys prob dont care haha

[VSPECT]

for me 5l/100km is freakn ace... ill be lucky to see anything close to 10L/100km...lol....i didnt notice any diff in fuel consumption...

5L/100km is what a diesel hatch would use haha. I was saying that I had lost around 5L/100km, so I was using around 15L/100km then it dropped to 20L/100km while I used the 5% ethanol shell fuel (without a tune for the fuel).

no difference in consumption for me and no knock. good for track days.

[limpus]

I'm getting 13-15L/100km in mine...and thats on a thirsty 3.0L 2JZ...so no difference really...
