The Ultimate Guide to Fuel Tank Capacity for Car Rental Uganda- Fuel is the lifeline of any vehicle. Without it, a car cannot move. Therefore, understanding fuel tank capacity is essential, especially for travelers using self-drive car rental in Uganda. Knowing how much fuel your rental car holds ensures smooth travel and prevents breakdowns.

How to Know Your Car’s Fuel Tank Capacity?
Every car has a fuel gauge on the dashboard.
- When the tank is full, the needle points to “F”.
- When the fuel is low, the needle drops to “E”, and a fuel light comes on to warn you.
The fuel tank itself is located in the basement of the car and connects directly to the engine system.
Most cars have a fuel tank capacity between 45 and 90 liters. However, SUVs and larger vehicles have bigger tanks compared to small cars.
Modern vehicles usually have a single fuel tank, while older models or long-distance trucks may have a secondary reserve tank. The reserve tank is about 15% of the main tank and is useful when traveling in remote areas.
How Much Fuel to Fill
You can easily check the maximum fuel allowed by looking at the fuel inlet cap, which often indicates the tank capacity.
For cars with a reserve tank, 15% of the primary tank is the maximum fuel for the reserve. Drivers should never drive on an empty tank. Always leave 5–10 liters in the reserve. Running completely dry can damage the engine and stop the car from functioning.
Can You Overfill the Tank?
Many drivers ask if it’s possible to put more fuel than the tank’s capacity.
The answer is no. Filling beyond the recommended capacity can prevent proper fuel flow into the engine. Overfilling reduces space for aeration, causes vapor locking, and may seriously damage the engine.
Always adhere to the maximum fuel level indicated on your car.
Driving When the Fuel Light Comes On
The fuel light typically signals that the tank is at a 10–15% reserve level.
When this happens, there is no need to panic. You can usually drive about 5 kilometers before refueling.
However, it is never advisable to drive on an empty tank. Doing so can weaken the engine because it receives less fuel than required for normal operation.
