Fuel Saving Tips

Go by bike - Occasionally

When the weather is good, and the days are longer, take the bicycle for some trips. I've been managing to commute to work by bike at least 1 day per week (its 25km each way, so takes about an hour x2). I'm saving 20% on my fuel bill and feeling fitter. You could also just cycle part of the way - drive half way, cycle the rest. Lots of benefits, few downsides if you want to make it work.
