Could anyone have a use for this, or am I going to have to just tip it away at the recycling centre?
It's nice and fresh, top tesco 95ron and an unknown percentage of Quantum Blue 15w40. Drained it out of Poppy's sump earlier on.
Moral of the story: Always make sure your earth leads are good!
(i'll revisit this in full later when I've had me long-delayed tea)
What the hell am I to do with four litres of 2-stroke fuel?

OK, the skinny....
Finally got to go and find out what's really wrong with Poppy that's baffled uncle's polish mechanic mate Chris.
Off I trot, get lost (bloody nonsensical motorway junctions), find rik1985austin's house, get working ECU from him - we should now share a moment's virtual silence for his GT, which was brutally murdered by a moron taxi driver last night ..................
......and eventually get to the site. Not quite the "garage" i was told (parking lot of a grotty shopping centre) but good enough.
Chris points out some earth wires he spotted with melted insulation - ok, wasn't expecting THAT - and that the alternator earth doesn't look up to snuff (suspected it before, but it seemed to work ok). Hook up jumpers, play about, do some experimenting on the fuel injector with unplugging cables, checking them with a multimeter etc, get some odd reactions (particularly after i noticed the fuel tank was bone dry and put a gallon in), particularly noting that a massive blast of fuel came out when i reconnected the cable just after trying to start it, with the igition still on. Cripes!
So a new earth lead and a new ECU later.......... it fires. And runs. And revs............... and pees chocolate milk everywhere out of the breather (airbox removed). I immediately crap myself thinking the head gasket's catastrophically ruptured..... but no... it smells distinctly of octane rather than horrid corrosive sugar water. The sump is FULL of petrol, and so are the fuel lines.
Which is how I ended up with nearly a gallon of ready mixed 2-stroke. And at least another pint of it on the floor... it gushes out FAR quicker than normal dirty oil. The cam protector flap under the oil cap was totally dry when i went to refill - never seen that before.
What had happened? Before arriving I suspected that the engine was getting no fuel, as had happened just before i sold it, either because of bad ECU, bad ECU contacts, or a bad relay. But instead, just the opposite - a fair bit of negative current, unable to easily get up the alternator earth, had zapped its way up the smaller earth cables, some of which route through the ECU.... sending it loopy and locked into MAXIMUM FUEL mode (which i suspect would be far too much even with the 1043 full throttle on the limiter), emptying the tank and flooding the cylinders beyond compare. Having put the piston rings in myself, I know that they should be pretty good at moving thick oil around when shifting at high speed - keeping thin petrol in place when mostly sitting still, another matter entirely...
So, always look after your earth cables kids....... this could be you
... cold, peed off, missing a day out of their weekend (5 hours of which spent on the road) and reeking of 95RON and 10w40.
EDIT: Pettsy....... that's timing
And that would have been the perfect way to get rid of the stuff spilt on the ground, had I been smart...... and had I been in possession of a lighter.
But............. what should I burn?
(now taking nominations - and donation bids - for people you dont like that i could put a burning pentagram on their lawn)

you're in wembley though, i guess i should have said i'm from brummagemshire....... the postage/travel costs would make the whole exercise just plain silly for what is, after all, about three quid's worth of octane/???-ane mixture
guess i'll just shove it in the astra's tank next time i run out (far less of a risk when you have a warning light
but it HAS happened before 
), mobile-google for the nearest filling station and top it all the way up after running for the minimum possible time
