1. Rolling Resistance: Assuming your tires are in decent condition (and if they're not, consider replacing them... you shouldn't keep tires for more than five or six years, even if they're not bald), inflate them beyond the door sticker pressure. For typical car tires, you will see massive reductions in rolling resistanceat up to 40 psi, after which, improvements drop off. 35 is a good midpoint. I've seen some service drivers use 45 psi in their car tires (truck tires are at around 50-60 psi standard). Only issue from doing this is it will hurt hijjus if you drive over rough roads all the time.
2. Start-up: Don't idle your car in the morning.
Repeat: DON'T IDLE YOUR CAR. Once you've checked your water and oil level, start the car, buckle in and adjust your mirrors and seat. The time you take to buckle in and get comfortable is all the time it takes for the oil to start circulating. Drive off as soon as possible.A cold car and carb use craploads of gas, so you might as well get a few kilometers out of them while the car is warming up.
3. Pulse and glide: You don't need to use gas every single second the car is moving. If you're coming up on a stoplight and intersection, just use enough gas to get going, then coast down to your target speed. In steady moving traffic, this is difficult, and it will get people mad at you, but traffic is not steady moving. Do it properly and nobody will notice you're doing it.
4. Brake less: Drive as if your brakes are dead. In other words, leave space enough so that if the guy in front of you brakes to a stop, you don't have to brake right away. Less stress pa. You won't be cursing and slamming on your brakes. This saves gas because you need gas to build up speed. If you use the brakes, you're scrubbing off all that speed you gained, and have wasted your gasoline investment.
5. Anticipate. Plan: If you pass lights with timers or are familiar with the traffic lights in your area, anticipate when they'll turn red or green. If you can coast down to a light without using the brakes, getting there just as it turns green, good. If you can avoid a red light by speeding up a bit, do so. Wasting some gas for a little more speed is better than idling at the stoplight for the next two minutes. Also, you know that jeepneys stop. All the time. Don't follow them too closely. Plan your overtakes ahead of time so you'll use as little gas as possible overtaking. Remember, also, that too slow is also a waste of gas. Dawdling along at 20 km/h leads to terrible economy. You should get best economy at around 40 km/h in the city and around 70 km/h on the highway.
Good luck!
