How My Fuel Consumption Improved 17.5%
Been struggling to get my fuel consumption below RM0.26/km recently. Per my records, I used to be able to get RM0.22/km and even RM0.21/km. Recent headlines about increasing fuel prices globally pricked my conscience to study the matter further.
I tried various hypermiling techniques. Driving like sailing (anticipating the traffic ahead to avoid braking as much as possible). Accelerating gently, treating the gas pedal like an egg shell. Even switching off the aircond when the weather got cool. To no avail. The petrol receipt mocked me each time I refueled. I can hear Opec ministers smirking with glee.
My googling yielded one final area I have not tried. A low-budget mod. I dropped by the nearest service shop and put it on for RM20, refreshed the tank to the fullest, and watched the fuel gauge meter breathlessly.
Eureka! I got a 17.5% improvement in the next tank. It's back to RM0.2194.
The solution? The humble and oft-neglected tire pressure.
Mine was 30 psi all round. I pumped it up to 33 psi front and 36 psi rear per recommended spec. Cost RM20 because it was nitrogen (normal air would also do.)
Who would have thought 3-6 psi made such a significant difference? RM20 recovered in a single fill-up. I'm back, baby! :rock:
Notes:
Fuel price : RM2.15/litre
Consumption :
