    carby engine vehicles flooding. Any carby that had a rubber tip on the needle & seat the E10 would eat away.
    I lost count of the number of EFI vehicles that would get towed in with a fuel fault & you would
    cut the injector fuel rail in half & it would be completely blocked.
    I think using E10 on any tuned modern HSV would be just asking for trouble..
    Maybe ring HSV & ask the question - they'd know better than anyone??
    Thanks for the detail.

    HSV just provide a standard, It's compatible as the engine has been "optimised" for a range of fuels, so it shouldn't be an issue, response.

    I expect it will run fine, and I suppose I'm looking for real world feedback on whether anyone has done it and if there was any noticeable impact.

    ive got a mate using E85 in a mid 90's honda with metal tank all he has done is change pump and hose to rail and never had any issues even metal tank dosnt show any signs of rust or corrosion, ethanol has too many internet myths made by people that dont use it and just hear that its bad especially the water absorbing its not enough to be an issue ever, my GTS has a E10 sticker on the fuel cap so im sure its fine to use all it does is change the AFR from 14.68 to 14.1 which is well within limits as your trims will prob be out further then that as it is
    Thanks for the detailed explanation.

    I expect it should be safe in mine then.

    E10 is a 95 octane fuel so essentially the same as running 95, not 91. I wouldn't run 91 in any V8. If the car has been tuned for 98, then don't run 95.
    Thanks for that.

    It has always been fed 98, but has a standard tune, and the fuel cap states "Premium" fuel and E10 compatible so a 95 Octane should be fine.

    91 was never on my Radar as an option.

    once u use ethanol u cant think of its ron number as the ethanol itself has way more benefit then just the octane it says, the e85 i use gets up to around the 110-115 octane but u will never get it to knock, ive had a pump fail going into boost and it leaned out that bad it missed enough to shutter the w**** driveline felt like it was going to fall out but as i was logging at the time still no signs of knock, 10% is good and 20% is all it needs to be at its best and any more percentage from that just adds to the cooling affect in the cylinder once ignited

    What about putting 50% E10 94/95 octane in and then you pay for 98 octane. End result E5 96 octane.

    Mines tuned for 98 only, so I can't (and wouldn't anyway). Do you have a better half that can use E10 in their car. Get them to give you the money for the E10 they put in and you still pay for 98 in yours.

    It's an idea, but messy and complex to manage.

    Fuel card use will require me to log mileage etc. so I will either need to fabricate numbers, (potentially criminal, so no), or be reporting out of sync fuel use numbers which could lead to my use being audited.

    I just get to nominate one car (which will have number plate recorded against this and the parking p*** in the work parking lot - so identifiable), and if not the HSV, then I will start using one of the others more instead.
