What You'll Learn
Fuel up when the light comes on
It is generally advised to fuel up your car when the light comes on. While it may seem harmless to delay refuelling, driving with the fuel light on can cause unwanted damage to your vehicle and cost you money in the long run.
When the fuel level sensor detects fuel below a specific point, the low fuel light illuminates on your dashboard, indicating it's time to fill up the tank. The fuel level sensor is typically triggered when 10 to 15% of the fuel remains in the tank. While there is no standard number of miles you can drive when the light comes on, it is generally safe to drive about 20 to 30 miles in a smaller vehicle or up to 50 miles in a larger one. However, this is not a hard and fast rule, and the number of miles can vary depending on several factors, including the type of car, driving conditions, and fuel efficiency of your vehicle.
Ignoring the fuel light and continuing to drive with low fuel levels can lead to premature damage to important components. For example, fuel pumps require lubrication and cooling from the fuel in the tank, so running on low fuel can strain the system. Additionally, driving at low fuel levels can cause debris and dirt to be pulled into the engine, leading to a clogged fuel filter and potential harm to the air filter and fuel pump.
To avoid these issues, it is recommended to refuel as soon as possible after the light comes on. If you find yourself critically low on fuel while searching for a gas station, you can conserve fuel by turning off the air conditioning and any unnecessary electronics, such as the radio or heated seats. Smartphone apps can also be helpful in locating the best gas prices near you before your light comes on.

Twice-weekly refuelling
Refuelling your car twice a week can be a good practice for several reasons. Firstly, it helps maintain a healthy fuel level in your tank, which is essential for your car's performance and longevity. Secondly, it can provide a sense of reliability and peace of mind, knowing that you have enough fuel to get through your daily commute or any unexpected journeys.
There are a few benefits to keeping your fuel tank at least half full, especially during winter. Firstly, it helps prevent condensation in the engine, which can freeze and cause issues with the fuel line. Secondly, having sufficient fuel allows for consistent accelerations, which can improve your gas mileage by up to 30% on freeways. Using cruise control, when possible, can also help conserve fuel and improve your vehicle's fuel economy.
For those with longer commutes or who drive frequently, twice-weekly refuelling ensures that you always have enough fuel to get you through your daily trips without worrying about running low. By refuelling more often, you can also take advantage of filling your tank before prices at the pump increase, helping you save money in the long run. This strategy is especially beneficial if you use apps to find the best fuel prices in your area.

Cost of refuelling
The cost of refuelling a car depends on several factors, including the type of car, the fuel type, the frequency of driving, and the distance travelled.
For example, the cost of refuelling a car with a petrol engine can vary depending on the size of the fuel tank and the price of petrol. In one instance, a user reported spending $60-$70 twice a week to fill up their car, while another user with a similar budget fills up their car only once a week. The type of car can also impact the cost of refuelling, as some cars have better fuel economy than others. For instance, a user with a Honda Civic reported refuelling up to three times a week, spending a total of $150 per week. In contrast, another user with a Corolla sedan spends $70 per week on refuelling, driving a similar distance.
Additionally, the frequency of driving and the distance travelled play a significant role in the cost of refuelling. A user with a long commute of 98km each way reported refuelling three times a week, spending $150 per week. On the other hand, a user who drives only 2.5km to work reported refuelling once every two or three months, with fuel prices at 220 cents per litre.
Refuelling fees may also apply when renting a car. Car rental companies, such as Hertz, charge a refuelling fee if the vehicle is returned with less fuel than indicated in the rental agreement. This fee covers the cost of the missing fuel and the service of refuelling. When renting a car, it is essential to refuel the vehicle before returning it to avoid additional charges.
With the emergence of alternative fuel technologies, the cost dynamics of refuelling are also evolving. For instance, hydrogen fuel cell cars, such as the Toyota Mirai, offer a lower environmental impact than traditional petrol and diesel vehicles. However, the cost of refuelling a hydrogen car can vary depending on the region and the availability of hydrogen refuelling infrastructure. While countries like Germany, California, and South Korea have made significant progress in building hydrogen refuelling networks, other regions may have higher costs due to limited infrastructure.

How low can you let your fuel get?
Firstly, it is important to note that driving with low fuel reserves is not advisable as it comes with risks. While modern cars give warnings about fuel levels, it is still possible to run out of fuel and become stranded, which can be dangerous for you and other road users. Additionally, driving with an empty or near-empty tank can damage various parts of your car, including the fuel filters, fuel pump, and engine. The fuel pump relies on fuel to lubricate and cool it during transfer, and without fuel, it can overheat and fail prematurely.
To avoid these issues, it is generally recommended that you never let your fuel tank fall below a quarter full. This will help prevent breakdowns and reduce the risk of damage to your fuel pump. Additionally, keeping your fuel tank above a quarter full can help you save money on gas by allowing you to plan ahead and find the gas station with the lowest prices, rather than having to rush to the nearest station when your fuel light comes on.
Some people may choose to fill up their cars completely when the fuel light comes on, while others may prefer to fill up when their tank is half full or once a week, regardless of the fuel level. This decision may depend on various factors, such as the distance of your commute, the fuel efficiency of your car, and your budget for gas.
In conclusion, while there is no one-size-fits-all answer to how low you can let your fuel get, it is generally best to avoid letting your fuel levels drop below a quarter full to prevent potential issues with your car and ensure a safer driving experience.

Fuel up before long trips
Fueling up before a long trip is a smart move, and there are some simple steps you can take to ensure you are as prepared as possible. Firstly, check your vehicle is in good condition. This includes checking your tire pressure and tread depth, as underinflated tires can cause poor gas mileage and increase fuel consumption by up to 1%. You should also check your battery, fluids, windshield wipers, and fuel filter to ensure your car is running efficiently and won't let you down on your trip.
Plan your route to avoid rush hour and busy roads, as idling in standstill traffic wastes gas. You can use a map app to help you stay on the most efficient route and avoid unnecessary delays. It is also a good idea to remove any unnecessary items from your car, as the heavier your car is, the more fuel it will use. Pack only what you need and be mindful of your fuel consumption by driving smoothly and efficiently. Try to avoid constant acceleration and deceleration, and use cruise control when appropriate to maintain a steady speed.
However, it is important to note that using cruise control on rolling countryside terrain is not recommended, as it can waste fuel. Instead, pay attention to your driving and use your judgment to maintain speed in a more fuel-efficient way. For example, when driving downhill, you can let your car speed up naturally without using extra fuel to maintain speed.
Finally, remember to fill up your tank before you set off! It is always a good idea to start your trip with a full tank of gas, and you may not know when the next opportunity to fill up will be.
