Quick answer: Driving the 95-mile Jurassic Coast from Bournemouth to Lyme Regis uses roughly 10 litres of fuel, costing about £14 (typically £14–£18) in an average car. Heavy summer traffic on the A35 and the steep "sawtooth" descents into coves like Lulworth and Durdle Door can cut fuel efficiency by up to 15%. Fill up at supermarkets in Bournemouth and Dorchester rather than remote coastal stations. Use the live map above for today's cheapest price.
How much fuel do you need to drive the Jurassic Coast?
Driving the 95-mile Jurassic Coast from Bournemouth to Lyme Regis requires roughly 10 litres of fuel, costing between £14 and £18 under normal conditions — about £14 for a typical 45 MPG car.
The 95 miles refers to the coastline; the actual drive constantly turns off the elevated A35 to descend steeply into coves and climb back out again. This "sawtooth" profile, plus heavy summer caravan traffic, means real-world fuel use runs higher than the flat estimate. Enter your own MPG and today's live price in the calculator below.
Why is fuel consumption higher on the Jurassic Coast in summer?
Heavy tourist traffic on the A35, combined with the geography of constant steep descents into coves and climbs back to the main road, means stop-start, low-gear driving that can drop fuel efficiency by up to 15%.
The A35 is the spine of the route and it's a UNESCO World Heritage Site draw, so summer brings serious congestion. Detours to Durdle Door, Lulworth Cove and Lyme Regis all involve steep coastal lanes. Tick the summer-traffic box in the calculator to model the penalty, and travel early or late in the day to avoid the worst queues.
Where should you buy petrol on the A35?
Major supermarkets in hubs like Bournemouth and Dorchester offer cheaper fuel than the remote, independent coastal stations located in the tourist hotspots.
The pattern is the familiar coastal one: fill up in the bigger towns before you head to the honeypots. Weymouth, Bridport and Wareham also have supermarket forecourts along or near the route. Avoid leaving it until Lulworth or Lyme Regis, where prices climb. Search a postcode like DT1 (Dorchester) on the map above and sort by cheapest.

Formula: (miles ÷ MPG) × 4.546 × (price ÷ 100) — 4.546 is litres per imperial gallon.

Which fuel does your vehicle need? A plain-English guide
The live map above covers all six fuel grades tracked under the GOV.UK Fuel Finder scheme. Here's what each one means — and how to choose at the pump before you set off.
The default pump for most petrol cars. Contains up to 10% ethanol. A small number of older or classic cars require E5 — check your handbook before filling.
Higher octane (97–99 RON) and cleaner-burning. Typically 10–20p/litre more expensive. The protected grade for older engines not approved for E10 — and popular with performance cars.
The default diesel pump. Contains up to 7% biodiesel. Suitable for all diesel passenger cars, vans and most HGVs. Generally 2–8p/litre cheaper than premium diesel at the same station.
Includes detergent and cetane-boosting additives. Sold as BP Ultimate Diesel, Shell V-Power Diesel and similar. Use the Premium Diesel toggle to compare the price gap near you.
Contains up to 10% FAME biodiesel — higher renewable content than B7. Only suitable for vehicles whose manufacturer explicitly approves B10. Always check your handbook first.
Drop-in renewable diesel with up to 90% lower lifecycle carbon than fossil diesel. Compatible with most modern diesels — check your handbook. Use the HVO filter above to find nearby stations.
Fuel for the Jurassic Coast's landmarks
The famous coves have little fuel nearby, so fill up in the towns first. Here's where to refuel for the big Dorset draws.
Widest choice of cheap supermarket fuel at the eastern end — fill up before you head west.
Nearest reliable forecourts before the steep lanes down to Lulworth Cove and Durdle Door.
Supermarket forecourts with the region's cheapest prices, mid-route on the A35.
Fill up in Bridport before the steep hills into Lyme Regis, where fuel is limited and pricier.
The two facts guides skip, both answered here: the route covers 95 miles, and the steep descents into the coves plus heavy A35 summer traffic reduce fuel efficiency by up to 15%. For live prices across Dorset, this page shares the GOV.UK dataset behind our UK-wide fuel map.
