11 Petrol station myths that could save you from maintenance issues in the future

petrol (1) There are many things that you might have heard about petrol stations. These may vary from when you should fill up to whether you should use your phone while waiting to fill up. How do you separate the fact from the fiction?

Filling up at a petrol station is a necessary evil for many South Africans but new research from data and analytics group Lightstone found that South Africans are covering less distance each month, but curiously are visiting petrol stations more often, with a 7% decrease in distance travelled and 2% increase in service station traffic. This indicates that South Africans are topping up their tanks with less fuel per visit, rather than filling up to the brim at every visit to the petrol station.

Making more trips to the filling station may be easier on your cash flow but if you aren’t quite sure what you should or shouldn’t do at a petrol station, you could be making a mistake that may damage your car in the future.

 

We bust some myths and shed light on the facts as we identify these 11 commonly held beliefs around petrol stations and fuel.

Myth #1 - Filling your tank in the morning gets you more fuel for your money: MYTH

Many people like to fill up in the morning believing that they get more fuel for their money. This myth is based on the theory that, if petrol expands with heat, it must contract with cooler temperatures. So, filling up in the morning when it is cooler must mean you are getting more fuel than if you fill up at midday.  

The fact is petrol stations store fuel in double-walled underground tanks that keep the fuel at a steady temperature. This means the time of day or temperature when you fill up doesn’t affect the density of your petrol. Midnight or midday - there is no difference. What you pay for is what you get!

Myth #2 - Using a mobile phone at a petrol station is dangerous: 

Myth

One widespread myth is that using mobile phones at petrol stations is highly dangerous. This is not true. Mobile devices are low-power radio-frequency transmitters (between 450 and 2700 MHz), with a peak power value that ranges between 0.1 and 2 watts. As explained in Blogthinkbig.com, the two common dangers that are thought to be related to the use of mobile phones are the possibility of explosions or fires. 


However, Blogthinkbig.com says: “The only way that a mobile phone could generate a spark at a petrol station would be due to a defective battery. This is unlikely, and could also occur in the case of the car’s own battery.”

Myth #3 - All petrol brands are the same: MYTH

Do you buy petrol based on price or convenience? The petrol we get in South Africa goes through the National Energy Regulator of South Africa which is responsible for regulating the petroleum pipelines industry in accordance with the provisions of the Petroleum Pipelines Act, 2003 (Act No. 60 of 2003). This means there is a standard that all petrol brands need to maintain. All fuel brands mix different additives into their fuel so petrol brands are never the same.

Myth #4 - Filling up with petrol while your car is running is dangerous: FACT

While this might be dependent on a number of factors, you need to be aware of the consequences of refuelling your car while it is running. It is definitely dangerous to refuel your car while the engine is running. It not only damages your car, but it can take only a drop of petrol for parts such as the engine, exhaust tailpipe, or catalytic converter to catch alight. Filling up while your car is idling can damage your car’s vapour recovery as harmful vapours are released when you fill up.

Myth #5 - Always queue on the same side as your fuel cap: MYTH

It makes no difference as fuel hoses can stretch around the vehicle to the fuel cap on the other side. It’s best through to park with your fuel cap on the same side as the pump as you’re less likely to be in the way of other vehicles.

If you’re unsure which side your fuel cap is look at your fuel gauge. Many vehicles have arrows on the fuel gauge that point left or right, indicating the side of the cap. This includes many Suzuki vehicles, and many drivers don’t notice this handy feature until it is pointed out to them.

Myth #6 - Pump your own fuel if you cannot see the station attendant: MYTH

Although there are many places in the world such as the USA, UK and France where petrol stations are self - service and people pump their own fuel. This is not the case in South Africa. The AA explains that there are specific laws in South Africa that prohibit South Africans from filling up their own tanks. There are various health and safety matters that we may overlook, and petrol pump attendants have been trained on how to work with fuel and use the various types of pumps. They are also trained in forecourt safety if there is ever a spillage or fire. 

One benefit of not filling your own car is  the smell of petrol which will linger on your hands. What if you have to go to a meeting, birthday party or dinner with friends? Wouldn't you prefer somebody else to deal with the potential spillage issue? For the record, the UK and France have not had petrol attendants for many years!

Myth #7 - You shouldn’t tip petrol attendants: MYTH

It's okay to tip petrol attendants. Let’s face it - they handle all the mess and fuss of filling up your tank, checking water, oil, tyres, etc. It’s only fair to tip the attendant who spends time outside in all types of weather waiting to serve you. It’s not a ‘must do’ but it is a show of thanks and is always appreciated.. 

Myth #8 - Petrol pumps are not accurate: MYTH

Petrol pumps are accurate. You need to be alert when you refuel your car. There are two steps you can take to make sure you receive the petrol that you pay for:

  • Always make sure that the pump board display reading is set at ZERO.
  • Get out of your vehicle if you can while the attendant fills up your tank. This way you can make sure what petrol your car is actually being filled with, checking what oil is used and most importantly being alert and aware about what is being done to your expensive investment!

Myth #9 - You should wait until your next car service to ensure that you’re running smoothly with every drive: Myth 

You should always keep an eye, or ear out, for issues that may occur with your car. New or different sounds can indicate that your car is starting to develop maintenance issues. Take your car to your local dealer and let them have a look at your car to attempt to diagnose the issues that could be causing those strange sounds and read up on what your warning lights mean.

Myth #10 - There's no harm in adding extra fuel in the tank ... right? MYTH

You may think that squeezing every last drop of fuel into your tank, or ‘fuel topping’ is a good idea, especially with the ever-increasing petrol price but this isn’t true. In fact, fuel topping can have negative effects on your vehicle. Fuel topping can either overwhelm your evaporative system and damage it or can cause a hazardous leak from the excess pressure in the system,” says Ed Nemphos, owner of Brentwood Automotive. Fuel topping can not only damage your car, but affect your pocket, and cause harmful vapours that pollute the environment. 

Myth #11 - Filling station owners determine the petrol price: MYTH

The general belief that filling station owners play a role in petrol hikes is a misconception. The petrol retail price is regulated by the government, and the calculation of the new price is done by the Central Energy Fund (CEF) on behalf of the Department of Minerals and Energy (DME). The profit earned by the business owner is regulated. It is not linked to the pump price but to the litres of petrol sold.
