Diesel Delivery Route Fuel Cost — 50 Miles Each Way

How We Calculated These Costs

Our calculation uses the current average UK diesel price of 146.2p per litre and an assumed fuel efficiency of 54 MPG for a typical diesel car. Here's the step-by-step breakdown:

1. Distance: 50 miles each way (100 miles return)
2. Fuel needed (one way): 50 ÷ 54 = 0.93 UK gallons (4.2 litres)
3. Cost (one way): 4.2 litres × 146.2p = £6.15
4. Annual estimate: 2 one-way trips per week × 52 weeks = £640 per year

Understanding Your Delivery Route Fuel Costs

For delivery drivers, fuel is a major operating cost. A 50-mile delivery route needs careful cost analysis to ensure profitability. Understanding your per-mile fuel cost helps you price deliveries accurately and identify the most cost-effective routes.

Diesel vs Other Fuel Types

Diesel engines typically offer better fuel efficiency than petrol, particularly on longer motorway journeys. However, diesel fuel costs more per litre. The break-even point depends on your annual mileage — higher mileage drivers tend to benefit more from diesel's superior efficiency.

Tips to Reduce Your Delivery Route Fuel Costs

• Maintain a steady speed and avoid harsh acceleration — smooth driving can improve fuel efficiency by 15-20%
• Keep your tyres inflated to the recommended pressure — under-inflated tyres increase fuel consumption by up to 3%
• Remove unnecessary weight from your vehicle — every 50kg of extra weight increases fuel consumption by about 1-2%
• Use air conditioning sparingly — it can increase fuel consumption by up to 10% in urban driving
• Plan your route to avoid congestion — stop-start traffic significantly increases fuel use
• Optimise your delivery route to minimise total distance and avoid backtracking
