Fuel goes off real quick. I complained to BP once about a shit batch of fuel that clogged up my fuel filter. I wrote it on a company letterhead (we spend an absolute fortune on fuel per annum) and they did not even bother replying.

If i leave fuel in my dirt bike for two weeks the thing can be an absolute prick to start. If it is fresh fuel from a busy servo it always starts first or second kick.

Cheers
