What octane fuel do you use?

biggest thing with with ethanol 85% mostly is just the startup u will get more condensation in the engine and thru the breather system, and some in the oil before it heats up, this can be helped as many make the e85 cold start so rich its is stupid and not needed all it does is absorb into the oil, just have to drive long enough to get the oil to 100c, a mate that got me into ethanol uses e85 only in a 96 honda with metal tank gets driven maby on weekend or monthly been bout 10 years now and never any issues with water or anything, only things changed was pump and injectors and couple hoses from the factory hardline, ive never seen milky goo in mine i only vent to air and all it gets on cold start is condensation fuely water in the can

The milky goo is from my Skyline days and running big boost, the RB's tent to push alot more oil from the heads, the oil and water from condensation makes the goo, and back then my catch can held about 3 ltrs, so it was a big bessie with alot of surface area for condensation to form

I actually removed the little SAAS oil air separator from my LS1 due to it not actually catching anything worth while, that was plumbed back into the intake, I would guestimate about 20ml captured every 5k km

I even added in some fuel foam thinking that the suspended oil was bypassing the can, nope, no real change

The can hit the bin and any blowby now just gets pushed through the engine with no issue

Although I wouldn't try that with a DI system, even with minimal blowby

what were we talking about again ..........lol

United petrol stations used to have a 100 octane fuel with E10. Dunno if they still have it as I don’t go there anymore.

That was P101, 98 octane with a splash of ethanol.

I'm happy with my 99 RON
I know you're all wondering where do I get 99 RON from... LPG folks

Where do they do LPG?

I haven't seen it around for ages in my neck of the woods

I use to own a 1985 Ford Bronco 5.8 on LPG, I eventually removed the gas to run it on 98 and make angy 4x4 powers

Finding LPG and compromised tuning was a PITA

I could get it running OK on either gas, or 98, but not both

It did use "all of the fuel" though

It did sound like war on full throttle though

I'm in NZ (North Island) it's everywhere. I have it in 3x vehicles. 2004 Commodore 3.8 Ecotec, 2011 Calais 3.6 LLT & 1996 Nissan Cefiro VQ20.
With our fuel cards it's 1.11 per liter

I used to run 102 octane in the RD race bike. Can't buy super anymore so creating my 102 blend can no longer be done.

Isn’t 98 with 15% E85 close, such should result in 85% 98 RON + 12.75% ethanol + 2.25% 91 RON and probably 100 RON

Dont blame me if the bike blows up on such a shandy

Can't run my bike on alcohol it's not tuned for it. Even E10 would likely result in a melted piston. I used to use 50/50 super and 98. Mix it together, leave it three days and a chemical reaction occurs and you end up with about 102 octane. Now I just run straight 98.

thats what united 98 and 10% ethanol use to be was called P100

It used to be an E5 but they don't seem to sell it anymore. Either that or they no longer tell you it has 5% ethanol.
