Since the switch to unleaded it has become very noticeable that the keeping properties of petrol have worsened. Left in an engine it soon smells stale and, given a few months, throws down an horrible 'varnish' which clogs things up no end. Does anybody know if this effect is purely due to the loss of the more volatile fractions or is there a chemical reaction involved ie, can fuel be safely kept for longer periods in sealed containers such as jerry cans?
