Tips to save Petrol

1) Pump up your tyres
Keeping your tyres inflated is one of the easiest and most important thingsone can do to improve fuel economy. Saving petrol means saving money. If a range is recommended by the manufacturer, the higher pressure should be used to maximize fuel efficiency. Deflated tyres run hot and jeopardize safety. It will also cause the tyres to wear out prematurely, affect the vehicles adversely, and hurt the fuel economy by increasing the rolling resistance. Tyres lose about 1 psi pressure per month due to air loss caused by the tyre hitting holes, bumps and kerbs. Therefore, the tyres should be checked at least once a month. Just 1 tyre deflated by 2 psi will result in a 1% increase in fuel consumption. 

2) Drive at moderate speed
Avoiding high speeds on open roads results in safer driving and better fuel economy. In highway driving, over 50% of the power produced by the engine
is used to overcome aerodynamic drag. Drag and thus fuel consumption increases rapidly at speeds above 90km/h. On the average, a car uses about 15% more fuel at 100km/h, and 25% more fuel at 110km/h compared to when it is doing only 90km/h. However, this should not lead one to conclude that the lower the speed, the better the fuel economy - because it is not. The fuel consumption of an average car increases sharply at speeds below 50km/h.

3) Clean the air-filter regularly
Clogged air filters increase fuel consumption by restricting airflow to the engine, and thus should be cleaned/replaced when necessary. Clogged air filters can increase fuel consumption by up to 10%.

4) Use thinner tyres
Tyres with thick width won't improve the handling of your car. Also, it will increase your car's fuel consumption. Thicker tyres mean more rolling resistance! , and thus will consume more fuel.

5) Start up the car properly
With today's cars, it is not necessary to prime the engine first by pumping the accelerator pedal repeatedly.Do not crank the engine excessively. This only wastes fuel. When starting the engine, idle it no more than 30 seconds to warm it up. An engine will warm up faster on the road. However, avoid sudden acceleration before the engine has warmed up sufficiently.

6) Drive in high gear (overdrive)
The engine runs most efficiently between around 1,500 and 2,500 rpm. To maintain these low revs you should change up through the gears as soon as practical and before the revs reach 2500 rpm. For automatic transmission cars, you should always switch on your overdrive to help saving fuel. Overdrive will allow your engine to change gears
at lower revs. It also puts your transmission into an "economy" mode and lets it engage the final "overdrive" gear when cruising to keep the rpms extra low, thereby increasing fuel
economy.

7) Travel light
Avoid carrying any unnecessary weight in your car. On the average, every 50kg added load in your car will increase fuel consumption by 2%.

8 ) Anticipate traffic ahead
A driver can reduce fuel consumption by up to 10% by anticipating traffic conditions ahead and adjusting the speed accordingly, and avoiding tailgating and thus unnecessary braking and acceleration. Accelerations and decelerations waste fuel. Braking and abrupt stops can be minimized by not following too closely and slowing down gradually when approaching a red light.
It takes up to six times as much fuel to move a car from a dead stop than it does for one moving at just a few km/h.

9) Avoid strong acceleration
The fuel consumption remains at a minimum during steady driving at a moderate speed of about 90km/h. Keep in mind that every time the
accelerator is hard pressed, the engine goes into a "fuel- enrichment" mode of operation that wastes fuel. The vehicle should always be gradually and smoothly accelerated

Ocasionally we do.. maybe it's good to join Club Hyundai in your case. You will learn more about maintainence of your car through fellow car owners of your same make.

Cheers

(From an industry expert in petroleum industry)

 

1. Fill up your car or truck in the morning when the temperature is still cool. Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you're filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant. Every truckload that we load is temperature-compensated so that the indicated gallon gauge is actually the amount pumped. A one-degree rise in temperature is a big deal for businesses, but service stations don't have temperature compensation at their

pumps.

 

2. If a tanker truck is filling the station's tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car's tank.

 

3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it's warm (gasoline storage tanks have an internal floating 'roof' membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation).

 

4. If you look at the trigger you'll see that it has three delivery settings:

slow, medium and high. When you're filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains more vapor, which is being sucked back into the underground tank, so you're getting less gas for your money.

 

Hope this will help ease your 'pain at the pump'

I have been monitoring my past two tanks ever since i adopt this method.. has shown some slight improvements.


FC from 13.2  to 14.3 (1st tank) to 14.5 (2nd tank).


 


Will continue to post my records online.

should pump late at night, your early in the morning should be before 7am, don't think many of us are awake at that time

My next two FCs

- 13.87 (3rd) 
- 15.42 (4th)

With fuel prices skyrocketing, I guess this method is really worth a try.

so you ask the uncle to squeeze the trigger in the slow setting?  they never eff you? 

or u pump yourself?
