What is the best and safest way to dispose of the old petrol?


Pour it into an old metal dish (baking tray?) and set fire to it in the
garden - a complete non-event provided obvious precautions are taken
... an opportunity for natural selection to come into play ;-)

Having seen the burnt legs of somebody who came bloody close to need a
skin graft after trying to get a barbecue going with petrol - I really
can't recommend it. He did *not* pour the petrol on the BBQ, he some
charcoal lumps in a bucket and poured some petrol on those (some way
from the recalcitrant fire). The trouble was that the fumes flowed out
of the bucket to the fire, ... and then caught fire - all the way
back to the bucket.

Really - don't do it!

I've burned petrol without any such drama. Pouring it into the (not
empty) ash bucket seems to work pretty well - it burned fairly calmly.
Obviously there's no opportunity for fume flowing in that case, because
any fumes will be burning instantly.

OTOH I didn't try to burn too much at once. If I was trying to shift a
few litres I'd probably try a bit and see how it behaved before trying
incrementally larger volumes. And keep the cap on the stuff I'm not
trying to burn :-)
