Fueling Tip: When to fill up

Fueling Tip: When to fill up Petrol or Gas

All of us are motorists and we all faced the uncertainties of fuel prices especially in this country.  In Malaysia, fuel prices are still bearable, but there is no doubt that fuel prices fluctuate a lot. Everytime there’s an announcement on fuel price hike, you see plenty of cars queuing up at gas stations before the stroke of midnight just to save a few dimes, oops cents. This kind of scene is just pathetic, isn’t it?

With fuel price hike and global commodity fluctuation, people are choosing hybrid cars to cut fuel consumption and a select few even took the plunge to join the electrification bandwagon.  Several local car companies and the Govt have collaborated to put up charging stations at select locations in the Klang Vallery. Electric cars have been received in this country, but it would take another decade or so before more motorists would consider a switch. So for the time being, its either petrol, most common, or hybrids.  

This guide provides a tip to get the most bang for your buck when it comes to fueling up. A correspondent in the Oil & Gas field who’s been in the line for 30+ years has provided allcarschannel.com readers with an insight into getting the most of every liter.

On the average, our source’s petroleum company delivers about 4 million liters in a 24-hour period through the pipelines. Going through the pipelines are diesel, jet fuel, petrol, LRP and Unleaded. The said fuel company has 34 storage tanks with a total capacity of 16,800,000 liters.

In the Oil and Gas industry, specific gravity and temperature of the products (petrol, diesel and jet fuel, ethanol and other liquified gas) play a crucial role. Even a one-degree rise makes a big difference during the transfer process from oil tankers to the gas station’s tanks. It is also important to highlight that gas stations do not have temperature compensation, like the refineries.

When’s the best time to fuel up

It is advisable to fuel up at the start of the day or early morning when the ground temperature is still cold. Also keep in mind that all gas stations have the storage tanks deep within the ground. Simply put, if you fuel up during the early morning, the ground is colder and therefore the fuel is denser. However, in the afternoon or evening, fuel becomes warmer as it expands. This means that a liter of fuel is not exactly a liter.

It is important to understand that when fueling up, you’re not to squeeze the pump trigger of the nozzle to a fast mode. For those who fuel up often, they should notice three modes on the nozzle’s trigger which indicates slow, mid and fast. Our expert advises that slow fueling should be the first choice because it minimizes vapor when fuel goes into the car’s tank. Do note that zll hoses at stations have vapor-return effects. Even if you’re in a bit of a hurry then go mid-speed, but do not choose fast mode as some of the fuel that goes into your tank becomes vapor. The vapor is then absorbed and returned to the underground storage tank. What it means is you’re getting less fuel for the total liters.

Fuel up on half-tank and not when the low fuel indicator blinks

The other tip is fuel up when your car’s fuel gauge hits half tank. The more fuel you have in your tank the less air is occupying the tank’s empty space. Moreover, fuel actually evaporates faster than you’d imagine. For general knowledge, fuel transporters have an internal floating roof. This roof serves as zero clearance between the petrol and the atmosphere, so it minimizes evaporation. All fuel trucks are temperature compensated to ensure that every liter of gas Is the exact amount. So, everytime you hit the fuel pumps, do not fuel up when a fuel truck is pumping gas into the underground storage tanks. The reason is as the diesel or petrol goes into the tanks, the fuel is being stirred up upon delivery. As a result, if you fuel up during the process you might pick up some dirt or residue that normally settles on the bottom of the tank.

You’ve now been empowered  to better understand about the fueling process and the whole nine yards, see if it helps you save fuel?
