    Your sympathy and understanding for my injury is overwhelming, thanks guys.

    Yeah its kinda Ok ,--its getting better and not worse,-- thats the main thing.

    Gasohol E85--- 95 octane here is 36 baht,-- regular 91 is 42 baht.

    30 baht to a US dollar.

    something tells me E85 and rum don't mix or did you change your shirt since that last romp in the bar. Might have been a reaction to something you spilled you know

    Na --it stung when the fuel touched the skin. Ive been stung by fuel before on even more sensitive areas than that but its never made a hole in me.

    Try some --dab a bit on your belly, Ide be interested to know what is does to you.

    Or dab a bit on the dogs bollocks.

    I wouldn't do that to the dog
    you should know better than that
    where's W Bad maybe we can get him to try it
    in a proper study there's always someone taking a placebo, IE taking the fake stuff, I'll do that one.

    this is out of norm for here. I have a dodge spirit 94 and has a 6cyl. it too runs on both, gas and E85. I now on gas i get about 32mpg with E85 i'll be lucky to get 20gpm Hwy.. so you can see the increase in fuel. Untill they get this and the desolving of rubber hoses etc.. don't use it. stay with gas or go to diesle

    I wouldn't mind the reduced mileage (due to lower energy content per litre) if the price were noticeably lower.

    But 89 octane E10 blends are going for $1.30 a litre this week, while the moonshine-free fuel (typically 94 octane or so) is something like $1.40 to $1.45. The difference is only worth it for high-compression engines that'll knock like crazy on the cheaper stuff.

    Also worth noting- I tried running a tank of last September's E10 in my Johnson two-stroke this afternoon. The thing's been full of fogging oil all winter and the gas had only a shot of the cheap generic brand stabilizer. Started with less than 2 seconds of cranking, ran fine all evening through the whole throttle range. Those of you who keep saying "we have ethanol problems", well, your gas companies must be way behind ours in technical competence (or cheapness) regarding additive packages.

    but you did add a fuel stabilizer
    if your outboard is an old model then the ethanol will destroy all the components not designed for it no matter what you add to it.
