Cut your fuel costs fast — See real savings from the first tank

If you run delivery vans, you already know fuel is one of your highest operating costs. Even a small improvement makes a big difference to your bottom line.

FuelMarble is a simple, one-time device that helps your engine burn fuel more efficiently. Because there is no complex wiring or mechanics involved, you can see how to install FuelMarble in minutes without any downtime. Just drop it in and start saving — most delivery vans see results on the same day.

And the best part?
FuelMarble usually pays for itself in 6–12 weeks.

Below is the real math behind how a single delivery van can save £300–£600 a year, and how a small delivery company can save £4,000+ annually without changing routes, drivers, or vehicles.

Case Example: How small delivery companies save over £4,000/year

A small delivery company operates 4 sub-2-ton trucks.
Each truck travels around 300 km per day, 22 days a month — that’s 6,600 km per month per truck, or 26,400 km per month across the fleet.

In the example below, this 4-truck fleet uses FuelMarble to achieve around 10% better fuel efficiency, saving over £4,500 per year in diesel costs.

The Fuel Costs for delivery company

Fuel efficiency: 10 km/L
Monthly fuel per truck: 6,600 km ÷ 10 km/L = 660 L
Fleet total: 660 L × 4 trucks = 2,640 L per month
Diesel price (UK): £1.43 per litre (as of 15 October 2025)

Monthly fuel cost (fleet):
2,640 L × £1.43 = £3,775.20 per month

Annual fuel cost (fleet):
£3,775.20 × 12 = £45,302.40 per year

With FuelMarble delivering around 10% fuel savings (within the 7–15% range), this delivery company saves roughly £4,530.24 per year on diesel alone.

The FuelMarble savings for this delivery company

By improving fuel efficiency by around 10% (within the 7–15% estimated range), this 4-truck fleet cuts its diesel spend by approximately £4,530.24 per year — money that can go straight back into driver pay, vehicle upgrades, or growing the business.

A four-truck fleet saving £4,500+ every year gains a real financial advantage. Lower fuel spend means healthier margins and more room to grow.

FuelMarble makes that possible with no installation, no disruption, and no learning curve — just immediate, real-world fuel savings from day one.

Realistic annual fuel savings for a delivery van

Baseline Assumptions

To ensure transparency, here are conservative operating assumptions based on real delivery fleets:

Annual mileage: 25,000 miles
Fuel efficiency: 35 mpg
Fuel price: £1.4 per litre
FuelMarble average improvement: 7–15%
Vehicle type: Diesel or petrol delivery van

Annual fuel cost without FuelMarble

25,000 miles ÷ 35 mpg = 714 gallons
714 gallons × 4.546 = 3,249 litres
3,249 litres × £1.40 = £4,548 per year

Annual savings with FuelMarble (7-15%)

Even the lowest real-world savings (7%) gives a strong return.
At 10–15%, the savings become extremely compelling.

Payback period: When do you break even?
