Want to Save Fuel? Here’s What Happens If You Only Fill Half a Tank! (The Nerdy Truth)

Fuel weight is reducing our fuel economy, but by how much? Does filling up half way twice save much more fuel compared to filling up a whole tank?

Find out the typical savings you would get if you carry less fuel weight between each fill up and decide if it's really worth it.

Is it true you’ll save money and fuel by only filling your car to half a tank instead of full? This question popped up in our eco driving comments, and it’s one of those practical myths drivers quietly wonder about while topping up at the pump. We crunched the real-world numbers to see if you’re actually wasting money by driving with a full tank—and the results might surprise you.

🔍 The Data: Does Fuel Weight Really Matter?
Petrol weighs 0.75kg per litre. On a typical 71L tank, you’re carrying 53.25kg of fuel when full, while half a tank is 26.625kg.

Driving on half a tank instead of full reduces the average fuel weight by 13.3kg during your journeys.

But what does 13kg less actually save you?

Every 50kg removed saves 1–2% fuel, so 13kg saves only 0.2–0.5% fuel per year.

💸 Real-World Savings Calculation:
If you drive 12,000 miles per year at 49 MPG, you’ll use 1,113.89L of fuel. At £1.43 per litre, that’s £1,592.86 per year on fuel.

A 0.5% saving = £7.96 per year.

That’s the realistic amount you’d save by filling up halfway instead of full. Is £8 worth the hassle of twice as many fuel stops each year?

🛑 Why It’s Usually Not Worth It:
✅ You’ll save £8 per year at best
✅ You’ll double your trips to the petrol station
✅ Most drivers could save 13kg just by clearing junk from the boot

Carrying umbrellas you never use, bottles of de-icer in the summer, or a spare toolbox “just in case”? You’ll get the same fuel-saving benefit by simply decluttering your car—without the inconvenience of more fuel stops.

⚡ Practical Tips for Fuel Efficiency:
Drive smoothly to reduce fuel use
Keep tyres inflated to the recommended pressure
Remove unnecessary weight from your car
Avoid excessive idling
Stick to manufacturer service schedules for clean injectors

🤔 Is Half-Tank Driving Ever Worth It?
For most drivers, it isn’t worth the effort. If you’re hypermiling to the extreme, you might care about that £8/year. But for nearly everyone else, fill up fully and drive normally. Focus on better driving habits and maintenance for real fuel savings.
