Fuel for thought…

When I started writing this entry, I was thinking of yet another “BOOO!” to the Malaysian government. But I think there’s more than enough of that on the Internet.. my adding to it won’t help matters.
The fact is, petrol prices have gone up. And we have to do something about it. No, not by complaining.. but by changing how we do things. Here I’ll present to you what I’ve been doing to save petrol.
- Avoid taking unnecessary trips.
- If possible, do your driving in the morning or evening. Cooler temperatures mean denser air which is easier on the engine. Plus, cranking up the air-conditioning in the afternoons just adds to your petrol consumption.
- Similarly, top up on your petrol when it is cooler. The cooler temperatures mean denser petrol.
- Don’t drive aggressively. Curb that right foot! The harder you accelerate, the more petrol you burn.
- Plan your trips to avoid jams and heavy traffic.
- Let your car coast in neutral. Of course, you have to make sure the situation is safe as a neutral engine means a lack of engine braking.
- Don’t leave your engine idling. When waiting for someone, turn your engine off. Too hot? Get out of the car and in the shade.
- A friend of mine does this in Australia, he turns off his engine when waiting at a long traffic light. Of course, you need to be familiar with the lights and anticipate when the lights will turn green so you don’t bring any unnecessary attention on yourself.
- Don’t drive with your windows down or your sunroof open. These create drag. The more drag you have, the more your engine has to work. Remove that bicycle rack when you’re not using it! Thinking of adding some cool rear spoilers? Think twice… those spoilers may look cool, but they also add drag. Besides, how fast do you think you’ll be going that you’ll need to add more rear downforce??
- Ensure your tyres are properly inflated. An underinflated tyre creates more rolling resistance. It also wears your tyres out. Oh, and remember.. a tyre’s pressure goes up after some driving due to heat build-up. So, if you drove 10 minutes to the petrol station and then inflated your tyre to the recommended pressure, chances are, it’s still underinflated. The recommended tyre pressures are for COLD tyres. So, overinflate your tyres at the station, get a pressure gauge and measure the pressure in the morning when they’re cold and adjust the pressures down accordingly. Need I mention not to overinflate your tyres past their recommended limits?
- Make sure your car is in tip-top condition. If your spark-plugs aren’t working as they should it means your petrol isn’t burning as completely as it should. Keep your air filter clean… a dirty filter means an inefficient engine.
- Polish your car! A clean car means less drag.
- Carpool! Yeah.. the added weight makes your car less efficient, but it sure beats driving two or three cars to work or to that mamak.
- Reduce weight! Stop carrying that bag of golf clubs in the boot!
- Do you leave your car to warm up in the mornings? Don’t! Just drive gingerly and you’ll be fine. Leaving the car on idle for 10 minutes is a sure fire way to increase your petrol consumption.
I’ve been practising some of these tips for the past 3 months. And it does affect my petrol consumption. My car’s trip computer calculates an average distance (km) per litre of petrol (L)consumed, or km/L. I used to get about 9.8 – 10.1 km/L. Now, I’m averaging 10.8 – 11km/L. At the maximum, it’s a 1.2km/L increase which means I can go 50.4km further on my full tank (42L) of petrol.
Give it a shot… and see what kind of improvements you get!
