Well last year I got truly caught short! One cold February morning we set off on a journey and promptly broke down 5 miles from the house. Solidified fuel in the tank , well it was -15c....Followed by a humiliating tow from the AA
So this year I'm trying Wintron XC30, a cold flow improver instead of the usual Synergy. I'm going to lag the fuel tanks with insulation at some point. Will keep you posted.
