How to make my car "greener"

Apart from making sure I get regular oil changes, having correct tire air pressure, replacing air filters, being less heavy on the pedal etc etc, what can I do to make my current car "greener"? Anyone has any good tips? (Not all of us can afford getting a hybrid right away:))

Begin it by removing any excess baggage..an extra 100lb of weight reduces fuel economy by up to two per cent. Then always check your tyre pressure if correct - this can sever 10 per cent of petrol costs.
