    No issues at all, but not my preference that's for sure.

    Should be fine,drive it to half tank then fill with premium...drive to low fuel level & back to normal.

    E10 is junk so will go through it quickly

    Long as you go through it quickly, ethanol is either wheat or corn so plenty of syrup if it sits unmoved to long, you can always put in a fuel additive to boost the stuff.

    The octane rating is higher than 91 and will do your car no harm at all especially if you only use it once. However for peace of mind check if your car is E10 compatible. Don't know why but some people use it all the time. Your economy will suffer and even though it is cheaper than 91 it certainly works out dearer.

    Its not simply an issue of octane rating in all cases as pre 1986, cars required the tetraethal lead to stop valve recession occurring. Some post ‘86 cars also can’t use e10 but presumable for reasons of octane rating.

    This post says it all, basically any commodore post 1986 won’t be damaged by running with e10.

    That's only the engine side, long term use can affect fuel hoses as well

    A tank of it here or there will be fine, as long as it's used quickly, ie within the week.

    funny how most say ethanol damages hoses but yet our fuel hose supplier had to get there e85 hose remade as the new BP98 would eat thru it, but is perfectly fine with ethanol...

    VS V6 fuel hoses have a plastic liner, e10 will not hurt the fuel system or the engine. e10 does have a better octane rating but ethanol has less energy compared to straight petrol so you need more of it to make the same power which is why most people notice a slight decrease in fuel mileage with e10 over straight 91ron fuel.

    Just drive the car as per normal and fill up with what ever you use normally at your next fill.

    I once had a problem with my VN where my garage had a radical slope and I had reversed in with very low fuel in the tank. So when I went to start it next morning it wouldn't pick up fuel. Living at the time quite a way from the nearest servo, too far to walk, I thought, what to do? So I poured a full bottle of straight metho in the tank, it started straight up and drove perfectly normally to the servo.

    E10 has a 94 octane rating, your not saving nothing as it almost levels out with the cost of 91 in mileage, so why risk it.
    91 still has ethanol but under 10% so they don't have to advertise it, this is why small garden equipment tell you to empty the tank and run the engine till it stops over winter / storage to stop the toffee like substance from blocking those little screens inside the carbie. This is the cause of most whipper snippers not starting after long storage unstarted with fuel lift in them.

    never seen this ? since my car has been off the road i left 1/8 tank of E85 in it for 12 months and its still fine to use, i also have drums of E85 and use a fuel pump to get it out of the barrels to fill my car then i just leave the pump sit on the drum in my shed with any ethanol left in the hose/pump and it has never shown signs of anything bad and still after years fires right up as normal dosnt turn to sludge/syrup/toffee, maby its the 2 stroke oil that mixes bad with ethanol for garden stuff ?

    Never had a problem using E10 in VR, VS, V6, V8 and also used E85 for years when our VE V6 was new and it was at least 10 to 15 cents cheaper per litre. Now with E85 always priced higher, it is not worth it as we did loose some distance per tank. Only use E10 when it is at least 4 cents a litre cheaper.

    Says the man who thinks there a thermostat in a commodore transmission, syrup, plastic like substance, jell, toffee, who gives a ship, it still leaves a film of soft rubbery toffee like substance blocking the filter.

    your talking about what petrol does when it goes off, nothing to do with ethanol, ever seen a petrol tank that has been left half full for a long time because the engine runs on gas ? even sloshing around in the tank with pump still running it turns the whole tank and fuel lines to sludge, ethanol dosnt do that it just evaporates

    Wont effect cars as I stated small engines. It doesn't go off as such more to drying out stagnate, All petrol goes off.

    Interesting... some details would be great as something in BP98 must be reacting with the hoses. Maybe the filter catches the crap or maybe some dissolved sludge gets through... but odd how the petrol stations and the fuel supplier always say there is nothing wrong with their fuel when one’s car runs rough after a refill :oops:

    Pure ethanol will fully evaporate but E10 & E85 do have storage issues. See fuel storage and handling factsheet
