  • Savings: 10-15% vs speeding

6. Air-Con Management

  • Below 50 km/h: Windows down (if comfortable)
  • Above 50 km/h: A/C on (drag reduction)
  • Temperature: 24-25°C sufficient
  • Savings: 5-10% fuel

7. Remove Unnecessary Weight

  • Savings: 2-4% fuel

8. Plan Routes

  • Use Waze: Avoid traffic jams

  • Time trips: Before/after ERP hours
  • Saves: Both fuel AND tolls

Smart Parking

  • Park in shade: Reduces A/C load on restart
  • HDB carparks: Often closer, less driving

Traffic Light Timing

  • Amber gambling: Costs more in fuel
  • Saves: 5-8% in city driving

Fuel Myths Busted

Myth 1: "Premium fuel improves economy"

Reality: Use manufacturer recommended grade only

Myth 2: "Fill tank half only to reduce weight"

Reality: Negligible savings, more refill trips waste fuel

Myth 3: "Coasting in neutral saves fuel"

Reality: Modern cars use less fuel in gear while coasting

Myth 4: "Warming up engine necessary"

Reality: Drive gently from start, engine warms faster

Emergency Fuel Saving

If Running Low:

  1. Slow to 50 km/h: Maximum efficiency
