    Going by the owners manual it may make slightly less power and get slightly worse economy but will be fine.

    It won’t hurt it; however, see how it goes. Our Ecomoo VS ran better enough on 95 that it felt like something was wrong on 91 ... and hence I only put 98 (it gets filled about once a month) in the VF.

    Run my l77 6ltr on 91 all the time and never notice any difference if i put 98 in.
    Its a daily driver though not driven like a race car.

    same, 98 mileage is about 0.1-2 better than 91/e10 (on the dash anyway which is not exact).

    Standard motor. I put 95 too. As Milo 6.0 mentioned, owner manual mentions it'll have slightly less power running 91.

    I wouldn't put 91 in it.

    I filled up this morning. United E85 $1.42 compared to $1.47 for E10. 105 octane too! More power, less emissions, made in Oz from renewable resources! Suitable for L77 as they have a flex-fuel sensor.

    Hi Geoff, I've always been under the impression that E85 burns faster, so more l/100 km.
    But I could well be wrong, so would be interested to hear what you experience.
    BTW - was the E85 at Dee Why United?

    This is correct, it has less energy in it so you have to burn more to get the same power. It's usually 20%-30% more or thereabouts, although if you've got a good tune on E85 vs a crap tune on 98 then your E85 results may look rosier by comparison (but then - this would be fixed with a better tune on 98! :)).

    There's also the fact that if I were to use exclusively E85, I'd be spending an extra 50km each fill-up finding a servo with E85. :)

    Indeed, along with today's price of 189.9 at the handful of United stations in Perth that sell it, they can keep it.

    E85 has less energy than petrol so you have to put approximately 1.6 times the amount of e85 than you would petrol. e85 has really good anti knock so you can run more timing ,compression and or boost as most turbo /supercharged are power limited by detonation but even na cars are pulling timing out of engine . E85 good for power not so good for fuel economy but if car is set up to suit you can get reasonable fuel economy and great power. Well that's my uneducated take on it anyway

    compression is king. much more efficient combustion means more power or less fuel for same power.

    I believe it is significantly cheaper over east.

    Yep, never sure what Monstar/Pirate was on about in the past.
    Alcohol based fuels have low energy density and carry water since they are unable to have water fully separated from them.
    I am unsure why they would be used on a street car, unless much lower priced to account for their lower energy output per litre. Which they aren't.
    Mostly based on helping political mates in NSW, in order to look after the sugar industry.
    But what would I know, I only studied chemical and mechanical engineering.

    I wouldn't know, have never actually seen an E85 bowser at any of the United's I've been too.
    Our local Caltex used to have a Flex Fuel bowser, but it was removed about 2 years ago.

    run cooler with boost is one reason. pirate has his compression significantly raised with engine work and hence needed ethanol which ran much more economically coupled with VVT and AFM/DOD. A big key is price at the pump compared to petty.

    yea pirate was getting around 6L/100 on ethanol so i wouldnt complain with that as u would be lucky to get a 6L engine on petrol down to that level even tuned

    No it's not.
    Especially considering the lower usage per litre. (energy density).
