Where to dispose of 5 month old unleaded petrol from my strummer

Options
Hi. Not sure if this is this the right place to ask, but I have half a can full of unleaded petrol leftover from not using my petrol strummer. The salesperson told me that unleaded petrol has only a 2 month shelf life. If that's the case, then how do I dispose of the petrol, given that it has oil mixed in with it as well. Thanks

    I only put the 2-stroke oil in small quantities of petrol - i.e. about a litre. I'll use just about all of that before it deteriorates. Once the petrol is a bit old, it goes in the tank of my car and I'll buy some fresh stuff for a new mix.

    If you put half a can of two-stroke mix into a full tank of petrol, I doubt very much whether it'd do any harm - it's too small an amount.

    Someone will probably come along in a minute and tell me that I'm wrong though... :p
    If you lend someone a tenner and never see them again, it was probably worth it.

    It was 100 ml oil into 5 litres of petrol so a very small amount.

    Chucked about 8l (5 in garage, 3-ish l in lawnmower) into the GS earlier, then filled it up at Tesco. They say use the high octane unleaded in it, I don’t, and I can’t see what harm it would do in an 80l tank.

    I did about 250 miles in it this afternoon, then filled it up again and it’s running fine!

    It is true that Unleaded deteriorates and becomes stale much quicker than the old leaded type used to.
    Next time you mix a can of fuel, put some Briggs and Stratton fuel additive in the mix. This will enable you to store unleaded for up to 2 years. It might possibly revitalise the fuel you have now.
    The unleaded you want to get rid off will not have deteriorated so badly as to be unusable in an older vehicle fitted with a carburetter provided it's diluted with fresh fuel. Give it to someone with an old car or preferrably a motorcycle. Do NOT use it in a car fitted with a catylitic converter. Please don't waste it, let somebody use it.

    Hope that helps
