Your car reminds you of refueling the tank by turning the fuel light on. Many drivers find it annoying and choose not to refill before driving a few more miles. Others freak out and head out straight away to the nearest gas station. Well, every driver should know some facts about the fuel tank capacity to avoid either damaging the engine or feeling too rushed.

What Is a Car’s Standard Fuel Tank Capacity?

The fuel tank is a part of the engine system that contains the flammable fuel such as oil. Most compact cars can carry something between 45 and 65 liters. However, SUVs and trucks have larger tanks while the size is smaller for the Nano cars.

Some vehicles have a secondary fuel tank called the reserve tank, which contains approximately 15% of the capacity of the primary chamber. However, it’s only seen in older vehicles or the ones designed for particular use and long distance.

The reserve oil is almost 15% of the total amount of fuel.

You have to read the writings on the fuel chamber’s cap to find out the capacity of your car. If it reads 60L, it means that it can contain 60 liters fuel. In modern vehicles, this quantity is inclusive of the reserve tank, which only indicates the level where the fuel light will warn you about a low level of gas. You should also know that you won’t be able to empty the tank because the engine will stop functioning when there are 5 to 10 liters left. Besides, 1 or 2 liters of gas will be unusable because it just keeps the sediments at the bottom.

Is It Possible to Fill Gas Tank Full or More Than the Rated Capacity?

Technically, yes and no. You cannot put 60 liters into a 55 liters container. On the flip side, the inlet pipe or fuel neck in some cases can hold 10 to 15 liters. Besides, most gas chambers are bigger than the rated fuel tank capacity because so that there’s room for air at the top, which helps to prevent vapor locking.

Overfilling the fuel chamber will cause engine damage.

You should not overfill the fuel chamber because it will not leave any space for the air. In that case, oil will have no room to expand when warm, creating pressure on the tank’s walls and leading to damaging the engine.

How Far Can a Car Go with the Fuel Light on?

You might have already checked the fuel tank capacity of your automobile. Well, it’s also important to know how far it can go when the fuel light turns red. You certainly don’t need to panic because the indicator just signals that the fuel has reached the reserve level, which is almost 10% to 15% of the total capacity of the chamber. So, it means that the car still has much juice to drag you a couple of miles. However, it’s not a good idea to drive until the tank is dry because you will only draw the sediment through the system and damage the engine parts because these will have more friction and be overheated because of the low level of fuel.

    Thac for this very important information regarding car fuelling tips. I have learnt muvhnon.this topic.

  3. David Mureithi says

    Thanks for the tip. I will no longer fill to the brim including the inlet pipe. I suppose the sensor stops further refuelling when this level is reached.

      Filling isnt bad but the matstu guys even lean the cars to increase the capacity. This is the bad bit.

    My question then becomes, when does the pump attendant know that he should stop filling the car with fuel, when the pump hose mechanism snaps back or when he see the fuel at the mouth of the fuel tank pipe??
