Fuel Savings for Family Cars and SUVs
SUVs and family cars with 60–70L tanks save more per fill than small cars. A Nissan Qashqai driver could save £450/year just by choosing the right petrol station.
Potential saving
Save £300–£600/year
for a typical family SUV
?The problem
The school run, the supermarket, the weekend trip to see grandparents — family cars clock up serious mileage and have large tanks to match. An SUV like a Nissan Qashqai holds 55–60 litres, and with real-world MPG of 35–40 MPG, fuel costs are a significant monthly outgoing. Yet most families fill up at whichever station is most convenient, without ever knowing whether a slightly different route would save them hundreds of pounds a year.
✓How WorthThePump helps
WorthThePump makes the decision instant. Scan your plate and the calculator pre-fills your car's MPG. Tell us roughly what you spend on a fill, choose your search radius, and the map shows every nearby station ranked by net saving — not just raw price. You'll see at a glance if the Asda 2 miles away genuinely beats the BP on the high street after accounting for the fuel you burn getting there.
- Larger tanks mean bigger absolute savings per pence per litre — the maths favours SUV owners
- Family driving patterns (multiple short trips) make regular cheap fills more valuable than sporadic long-distance savings
- See annual saving projections based on your fill frequency — useful for household budget planning
- Hybrid SUVs are supported — the calculator understands petrol-electric vehicles and applies the correct MPG

Common questions
Does driving an SUV mean I spend more on fuel even if I find cheaper petrol?
SUVs typically have lower MPG than small hatchbacks, so they use more fuel per mile. But this also means the absolute saving from cheaper petrol is higher. A 10p/litre saving on a 55L fill is £5.50. On a 40L fill, it's £4. The lower your MPG, the more each pence per litre matters — which makes WorthThePump more valuable, not less.
My car is a hybrid SUV — does the calculator work?
Yes. Hybrid petrol SUVs (Toyota RAV4, Kia Sportage PHEV in HEV mode, Hyundai Tucson hybrid) are fully supported. The calculator automatically identifies hybrid vehicles from the DVLA lookup and uses the appropriate MPG figure. The fuel type defaults to petrol for hybrid vehicles, which is correct for fuelling purposes.
Should I always fill up fully or is it better to fill half a tank?
A full tank adds weight, which slightly reduces MPG. But the difference is negligible for typical family driving. The more important variable is the price at the pump — use WorthThePump to find the cheapest station, then fill up as much as makes sense for your journey pattern.
How often should I check fuel prices?
Fuel prices change daily at many stations. If you fill up weekly, it's worth a 30-second check before each fill. WorthThePump data is updated hourly, so you're always seeing current prices. Petrol prices tend to drop on Mondays and Tuesdays and peak on Thursdays and Fridays — checking mid-week often finds the best prices.
