Cheers Edward - not sure I agree about filling a tank with gas?
If the water is either in the tank already or in the petrol you buy - it will remain in the tank - I can see the logic though.
And I'm sure I remember a thread about petrol starting to degrade after a possible 6 weeks or so as well of storage.
Thanks anyway...
ps - Can u please teach me how to get MYyy knee down on my SS (or are you just 7 feet tall

).
