Owners of sedans and liftbacks Skoda Octavia Often face the need to clarify the technical characteristics of your car, especially when it comes to the range of travel. For the 2018 model, which is the A7 generation (facelift), this parameter is one of the key when planning intercity travel or calculating the cost of ownership. Not everyone knows that tank volume can vary depending on engine type and configuration, although most sources point to averaged values.
Understanding the real amount of fuel your tank holds Skoda OctaviaIt helps to avoid situations where the fuel pump is idle due to insufficient fluid levels. In this article, we will analyze not only factory figures, but also the nuances associated with the design of the fuel system, as well as how these data affect the real range in various operating conditions.
Official technical characteristics of the tank
Manufacturer Skoda Auto For most of the modifications of the 2018 model, a single fuel tank volume standard was laid down. The technical documentation indicates the value 50 liters for petrol versions and 50 liters for diesel units. However, there are exceptions related to markets or specific versions, for example, for taxi services or regions with special climatic conditions.
It is important to understand the difference between total volume and work volume. The factory figure includes the space occupied by the fuel pump and the rough cleaning filter, as well as a small margin that is not consumed until complete devastation. If you see a low fuel indicator on the dashboard, it means that there is approximately a fuel in the tank. 7-8 litersNot that the container is completely empty.
- π’οΈ The standard tank volume for all major modifications of 2018 is exactly 50 liters.
- β½ The minimum fuel supply at which the lamp lights up is 7-8 liters, depending on the calibration of the sensor.
- π In modifications with gas-cylinder equipment (GBO), the regular tank can be reduced or replaced with a special compact tank.
Do not confuse the volume of the tank with the engine. Many drivers mistakenly believe that a more powerful engine requires a more capacious tank, but in the case of a more powerful engine, it is not possible to use a larger tank. Octavia It's not. Body design of liftback or station wagon Skoda Octavia Combi does not allow to significantly increase the dimensions of the fuel tank without losing useful space of the trunk.
Differences depending on engine type and configuration
Although the base tank volume remains the same for most versions, there are nuances related to the type of transmission and drive. For all-wheel drive versions Skoda Octavia 4x4 suspension design and the presence of a driveshaft may slightly affect the shape of the tank, but its capacity remains at the level of the 50 liters. The exception may be special versions for taxis, where sometimes larger tanks are installed.
In the case of hybrid modifications or cars with start-stop systems, the tank volume also does not change, but the fuel consumption mode changes. Engines. 1.4 TSI and 1.6 TDI They consume different amounts of fuel, which directly affects the mileage to the next refueling. It is important to consider that the fuel level sensor may have an error, especially in case of abrupt changes in ambient temperature.
- 1.4 TSI (Petrol)
- 1.6 TDI (Diesel)
- 1.2 TSI (Petrol)
- 2.0 TDI (Diesel)
- Other
There are also versions with a factory installation of gas cylinder equipment, which can have a reduced volume of the gasoline tank. In such cases, the bulk of the volume is the gas cylinder installed in the spare wheel niche or in the luggage compartment. This is critically important to consider when planning long trips, as the range of gas and gasoline will differ.
- π§ The all-wheel drive versions retain the standard tank volume of 50 liters unchanged.
- π Special taxi versions can have an enlarged fuel tank of up to 60 liters on request.
- β½ Modifications with HBO often have a reduced gas tank, but an increased total power reserve due to gas.
When buying a used car in 2018, it is recommended to check the actual volume of the tank, as the previous owner could install non-standard equipment. This is especially true for versions that have been used in the enterprise sector or delivery services. This information will help you avoid surprises on your first long-haul flight.
Calculation of real range and fuel consumption
Knowing the exact volume of the tank, you can independently calculate the potential power reserve of your tank. Skoda Octavia. To do this, divide the tank volume by the average fuel consumption and multiply the resulting number by 100. For example, in the case of volume 50 liters and 6 litres per 100 km You can theoretically drive about 830 kilometers. However, reality often makes its own adjustments to these calculations.
Fuel consumption directly depends on the driving style, vehicle load and the condition of the road surface. In an urban cycle with frequent traffic jams and stops, the consumption can grow to 9-10 litersThis reduces the range to 500-550 kilometers. On the road, with a calm ride and maintaining a speed regime of 90-100 km / h, fuel consumption is reduced to 5-5.5 litres.
| Engine type | Tank volume (l) | Average consumption (l/100 km) | Approximate range (km) |
|---|---|---|---|
| 1.4 TSI (Petrol) | 50 | 6.5 | 760 |
| 1.6 TDI (Diesel) | 50 | 4.5 | 1100 |
| 2.0 TDI (Diesel) | 50 | 5.0 | 1000 |
| 1.2 TSI (Petrol) | 50 | 6.0 | 830 |
Diesel versions Skoda Octavia 2018 has the greatest range due to high engine efficiency and lower fuel consumption. Owners of such cars often ignore the gas station for several days, which can be convenient for long-distance travel. However, it is worth remembering that the engine at an extremely low level of fuel can lead to overheating of the fuel pump.
β οΈ Warning: Operating a vehicle with a fuel level below 10% of the tank volume can lead to suction of sediment from the bottom of the tank and damage to the fuel filter or pump.
How does temperature affect the volume of fuel?
At low temperatures, the fuel is compressed, which may slightly reduce its volume, but the density increases. At high temperatures, expansion occurs, but it does not affect the mass of fuel you refuel. The main thing is not to leave the tank full in the summer when parking in the sun to avoid evaporation through the ventilation system.
When planning a trip, it is important to set aside a 10-15% reserve in case of unforeseen circumstances, such as traffic jams or the need to deviate from the route. Do not expect to reach the next gas station if the indicator has already caught fire. It is better to be safe and find gas stations in advance, especially in remote areas.
Refuelling nuances and ventilation system
Modern cars including Skoda Octavia In 2018, they are equipped with a complex fuel tank ventilation system that prevents the release of gasoline vapor into the atmosphere. This system includes adsorbers and valves that can create resistance when refueling. If a gas station gun often fires off, you should not try to pour more fuel with force.
Attempts to βpressβ the fuel in the tank can lead to the ingress of liquid fuel into the adsorber, which will put it out of order. Repairing this system is expensive and requires replacing expensive components. It is better to stop when the gun is fired for the first or second time, as this means that the tank is filled to the standard level stipulated by the design.
βοΈ Safe refueling rules
Fuel tank cap on Octavia 2018 has special protection against unauthorized access and must close before the characteristic click. If you hear a whistling of air when you open the lid after a long trip, it is normal to indicate a pressure leveling. Ignoring this sound can lead to depressurization of the system and errors on the dashboard.
- π« Never try to fill up more fuel after shooting the gun automatically.
- π Always twist the tank cover to the click to ensure the system is tight.
- π‘οΈ Consider the temperature expansion of the fuel, especially in hot weather, do not overflow the tank.
Before refueling at an unfamiliar gas station, it is better to use fuel with an octane number recommended by the manufacturer to avoid detonation and loss of engine power.
β οΈ Attention: The hit of liquid fuel in the adsorber due to overflow of the tank can cause an error of the environmental system and the appearance of the smell of gasoline in the car.
The influence of fuel quality on engine performance
Fuel quality plays a crucial role in the durability of the engine and fuel system Skoda Octavia. The use of low-quality gasoline or diesel with impurities can lead to clogging of the nozzles and failure of the high-pressure pump. This is especially true for engines. TSI and TDIThey have high requirements for fuel cleanliness.
It is recommended to refuel at verified network filling stations, where quality control is carried out regularly. Savings on fuel often result in costly repairs that can exceed the cost of the difference in the price of fueled fuel. Owners of diesel versions should also pay attention to the seasonality of the fuel to avoid problems with the solidification of the diesel fuel in winter.
The use of high-quality fuel is not just a recommendation, but a necessity to maintain the efficiency of modern direct injection engines.
If you still refueled at a questionable refueling station and noticed a decrease in power or uneven engine operation, it is recommended to conduct a diagnosis and, if necessary, replace the fuel filter. In some cases, a fuel system may need to be flushed. Do not delay the solution of this problem, as the consequences may be irreversible.
Specifics of operation in winter
In winter, the volume of the tank remains the same, but the behavior of the fuel changes. Diesel fuel can thicken at low temperatures if it is not season-appropriate. For diesel versions Skoda Octavia In 2018, it is important to use a winter diesel fuel or add an antelene to the fuel in advance. This will prevent the formation of paraffin crystals that can clog fuel filters.
Gasoline engines are less sensitive to cold, but also require attention to fuel quality. In severe frosts, the condensate in the tank can freeze and block the fuel line. To avoid this, it is recommended to maintain the fuel level in the tank at least half, as water accumulates at the bottom of the tank.
What to do if the engine does not start in winter?
Check the fuel level and its quality. If summer diesel fuel is used, it could thicken. Try to drive the car into a warm room or use a preheater.
In winter, it is also worth considering that during long parking in the cold, part of the fuel can evaporate or condense. This does not affect the volume of the tank, but can lead to the formation of water in the system. Regular operation of the vehicle and maintenance of fuel level help to minimize these risks and ensure reliable engine start-up.
Owner Frequently Asked Questions (FAQ)
What is the real volume of the tank of the Skoda Octavia 2018 with a 1.4 TSI engine?
The official fuel tank volume for all 2018 versions of the Skoda Octavia is 50 liters. This applies to the 1.4 TSI engine and other petrol and diesel engines, unless additional equipment is installed.
Can I pour 55 liters in an Octavia tank?
No, the physical volume of the tank is limited constructively. Attempting to pour 55 liters will overflow the ventilation system and get fuel into the adsorber, which can cause serious breakdowns and the smell of gasoline in the cabin.
How often should I change the fuel filter for Octavia 2018?
The manufacturer recommends changing the fuel filter every 60,000 km or every 4 years. However, when using low-quality fuel, this procedure should be carried out more often, for example, every 40,000 km.
Why does a low-fuel lamp light up, but I can still drive a lot?
The lamp lights up when about 7-8 liters remain in the tank. This is a backup volume that allows you to get to the nearest gas station. Do not use the car on this stock constantly, as it harms the fuel pump.
Does driving style affect tank volume?
Driving style does not affect the physical volume of the tank, but directly affects fuel consumption. Aggressive driving with sharp accelerations can increase consumption by 20-30%, which will reduce the real range until the next refueling.
