This time of year you are using more accessories to make life bearable
heater fan, heated rear screen and lights all will increase your fuel
consumption just something you have to live with - not that its cost
effective but an engine preheater will lessen the warm up time which is when
your fuel consumption is at its highest or increasing your tyre pressure
slighty say + 2psi helps but you risk lessening grip of course.
