Removing ethanol from petrol .
After initial trials the cleaned fuel burns better and stores better, things like brush cutter, chainsaw and small gennys and power sythe all start with ease and run smoother.
Theres nothing worse or frustrating cursing and swearing at a generator ala Basil Fawlty in minus double digit temperatures when the power goes out again.
Time consuming yes , but in my opinion worth it. Its a shame that ethanol free fuel isn't available in our area( Esso Synergy Supreme+ Unleaded 97 ) and Aspen is now about £5 a litre .
