Hi guys!
just wanted to know and gain some feedback knowledge on 95 premium in general; is good? and if the 95 premium is good at Caltex?

Hi guys!

thanks guys.
what do you define as "good"? Are you talkig about from a performance perspective or fuel efficiency perspective?
It runs fine, doesn't ping and isn't any less fuel efficient than 98 which is why i don't bother with 98 any more.
unless ur car's tuned to use 98.. then don't switch
Please search, there is already a thread discussing petrol.
quite simple.Quote:

Not sure if Shell still has it anymore.
Where do I get e85 (wait wtf is e85)
e85 is ethanol 85 (85% ethanol), I haven't seen it in Australia before, you usually find it in other countries.
I think its more common in Europe.
95RON is good for most later cars, European cars are apparently all meant to run on it for better economy and less pollution.
lots of cars that are 2000+ have a 95+ octane recommendation. I know my 03 Jazz does.
98RON though is the best as far as economy, performance and availability are concerned.
According to my manual for the late 70's, my car can handle anywhere between 92 and 98... I'm pretty scared to use 98 though :|

e85 is good for boosted cars, + kw yo
but for d15bs no need for e85
you need to tune your car andget injectors for e85

It is cheaper than regular petrol however it burns 30% quicker
You also need to upgrade the fuel system components
95 octane is fine on your EK1 engine.
the AFR for e85 is lower ie more less air and more fuel required.Quote:

either way the car owners manual should say what fuel to use.
i would never by regular unleaded/91RON or what ever it is, i question using that stuff in my lawnmower.
Only reason I asked was I see people posting tunes on 98 and then e85 and I was like doesn't e stand for ethanol, how could man e85 be better than 98 lol and yes now I'm enlightened
If your building a drag/track car or looking for big numbers E85 is the way. Very costly tho, you require bigger injectors, higher flowing pump and use more juice. But I generally find ultimate/vortex is good. If I have the money I go V power and a fuel stabilizer (I find with the stabilizer it gets better kms, otherwise I would rather water)
Because do a google search for the benefits of e85.Quote:

because rather than copy pasta all the info here, its easier to just look it up.
prices for fuels off the ****ing moon !!
170+ bp ultimate and shell vpower du ma
wow caltex 98RON near my house is usually 159.9 which is funny cause no matter how cheap the 91RON gets the 98RON is always 160ish.
Generally whatever the 91/e10 cost is ... 98rons are normally 15-20cents more... Whereas E85 would be about 10cents less than your 91rons.Quote:

please don't whinge about high prices.
In Europe they pay over 2 dollars a litre.
They also pay half the price for most cars that we consider "luxury" vehicles - we're not talking about economies of scale here
Probably 25+ Servo's across Sydney now stocking E85, a mate has an E85 tune for his track XR6T.
The benefits are huge for him as his engine runs much cooler now, he gained around 30kw with the switch to E85, he now puts 347kw to the ground with the stock turbo. The only downside is ya need to drain the tank before either filling with E85 or refilling with regular. The stuff aint cheap either.
My mates been egging me on recently to grab a Hondata and run E85 for the track. Gotta say I'm a little tempted, he was gunna find out from his tuner if it was possible ??.
Its all possible - did your mate change his fuel filter? Tell him to change it to an alcohol fuel style filter before the standard carbon filter falls apart and destroys his motor... I have seen this happen in falcons on E85
Your civic may not get such a big advantage with E85 unless you are running high compression or forced induction (effective high comp). I would save your money and change other aspects of your car like tyres or suspension if you haven't done that already.
Yeah hes aware of the fuel filter situation. So how much higher does the comp ratio rise ? Would the stock piston not cope with e85 if it was just used on trackdays ? Already sorted my suspension so any minor power upgrade would be welcome.
Cheers
E85 won't increase your compression, the benefits are really only seen when its added to a high comp motor - i can't think of the exact wording to explain it right now, but i've seen a conversion on a low comp N/A motor (427ci V8) and the results were fairly insignificant over 98ron
I think what you're trying to say Pat, is that e85 really only sees significant gains in high boost and high compression cars because it allows you to advance the timing further than regular pump fuel, because due to the higher octane, its more resistant to detonation.
This results in higher power figures.
Yeah, thats about it - sorry, work and small hangover is causing me to struggle today... lol

Just curious, but what sort of compression number would you need before getting the benefits of E85 in a NA motor ?
This is a bit of a stab in the dark, but I would guess around 12 or 13 to 1
Off topic but I've heard that you looking for more then 12 and up to 14.
Also saw somewhere some guy saying you could run like up to 20:1 on e95
You can run almost any compression rate with E85, its just the amount of timing you can dial in...
Most turbo motors run an effective compression ratio of well above 20:1 once you take into account the boost being a multiplier
Yes exactly. But if timing is stock it might be safer to keep compression lower to prevent detonation.
Isn't it?
I'm not sure where you're going here... If you are increasing the comp, timing will have to be set - if your timing is at stock settings, your engine set-up (and compression) should be pretty stock otherwise you'll have all sorts of issues with detonation due to Air Fuel Ratio's being different I would assume...Quote:

Yeh I can't remember what my point is. I'm just bored at uni trying not to fall asleep.
Lol, fair enough
