Ran out of two stroke petrol additive on Sunday, and wanted to take the scoot out for a spin. I'd heard of washing up liquid being used before, so thought I'd give it a try.
I added some Fairy liquid to the petrol, and apart from the odd bubble coming out of the exhaust, it seems to work fine! I guess it will keep the piston and barrel nice 'n' clean as well!
Anybody else used this before or tried anything else as a substitute?
