Follow the 20/4/10 rule when buying a car.
Put down a deposit of at least 20%. Don’t finance the car for more than four years, and spend no more than 10% of your gross income on transportation costs (including petrol, maintenance and insurance). Some believe you should only buy a car you can afford to pay cash for.
2. Keep a ‘light’ foot on the pedal.
Smooth driving that includes changing gear when the appropriate rev levels are reached and adherence to speed limits will keep fuel consumption to a minimum. “The more conservatively you drive, the more you can reduce costs,” says Des Fenner, general manager of Datsun South Africa. Other tips that help keep consumption costs down include minimised idling, minimal use of air conditioning, keeping windows closed while driving to reduce drag, and avoiding unnecessary short journeys.
