Petrol motorhomes: Are petrol campervans the future of UK leisure travel?

Quick Answer

Petrol motorhomes and campervans are likely to play a much bigger role in the future of leisure travel, especially for owners who use their vehicle for short breaks, city access, weekend trips and occasional touring. Diesel still makes sense for heavier motorhomes, towing and high-mileage motorway use - but petrol is becoming a more attractive choice thanks to cleaner urban access, lower used purchase prices, quieter driving and fewer diesel-specific maintenance issues.

In short: if you mainly tour long distances, a modern Euro 6 diesel can still be a strong option. If you want flexibility, quiet running and low-emission-zone access for mixed use, a petrol or petrol-hybrid model could be the smarter long-term choice.

For decades, the standard recipe for a leisure vehicle was simple: buy a large diesel van, convert it, and hit the open road. Diesel engines were championed for their high torque, load-lugging capabilities, and impressive long-haul fuel economy. However, the automotive landscape is experiencing a seismic shift. With the expansion of clean air initiatives across the UK and Europe, the spotlight is rapidly turning towards petrol campervans.

In this comprehensive guide, we explore the technology, the economics, and the practicalities of choosing an unleaded engine for your next great adventure.

Who is a petrol motorhome best for?

A petrol motorhome or petrol campervan suits drivers who want flexibility rather than maximum towing power. It is particularly well suited to:

•      Weekend travellers and short-break users

•      Campervan owners who drive in and around towns or cities

•      Buyers looking for a used van conversion more likely to meet clean air zone standards

•      Owners who value a quieter, smoother driving experience

•      Travellers who do not want to worry about diesel DPF issues caused by repeated short journeys

•      People who want a future-proof stepping stone before moving to hybrid or electric leisure vehicles

However, diesel may still be the better choice for very heavy coach-built motorhomes, frequent towing, high annual mileage or regular long-distance motorway touring.

The shifting tide: why unleaded is gaining ground

The primary catalyst for the rise in petrol-powered leisure vehicles is environmental legislation. Across the UK, cities like London, Bath, Bristol and Birmingham have introduced Ultra Low Emission Zones (ULEZ) or Clean Air Zones (CAZ). Older diesel engines face hefty daily charges to enter these areas, whereas many older petrol engines remain exempt due to lower nitrogen oxide (NOx) emissions. Consequently, the demand for low-emission zone-compliant motorhomes has skyrocketed.

When weighing up the petrol vs diesel camper pros and cons, it is essential to look beyond the fuel pump:

	Diesel	Petrol
Pros	Better fuel economy on motorways; higher low-end torque for towing and heavy payloads	Generally cheaper to buy used; ULEZ compliant for older models; smoother and quieter ride
Cons	Heavy emission penalties; expensive DPF repairs if not driven regularly on motorways	Lower torque on steep hills; historically worse fuel economy (though modern turbochargers have largely closed this gap)

 

Are petrol campers better for short trips?

A frequent question from weekend adventurers is: “Are petrol campers better for short trips?” For many owners, the answer is yes.

Modern diesel engines are fitted with Diesel Particulate Filters (DPFs), which need the right driving conditions to regenerate properly — usually longer, hotter journeys rather than repeated short, low-speed trips. If you mainly use your campervan for weekend getaways, short local drives, shopping runs or coastal roads, a diesel engine may be more exposed to DPF-related issues over time. Repairs can be costly.

Petrol engines avoid the DPF problem entirely, making them a strong choice for intermittent leisure use. Some newer direct-injection petrol engines may use petrol particulate filters, but these are not the same as diesel DPF systems and are generally less associated with short-trip reliability concerns.

For owners who use their campervan as both a leisure vehicle and an occasional everyday vehicle, petrol can therefore offer a simpler and more forgiving ownership experience.

Practical perks of petrol power

The sound of silence

One highly underrated benefit of choosing a petrol engine is acoustic comfort. Unleaded engines produce significantly less vibration and clatter than diesels. If you are creeping into a secluded Scottish glen or arriving at a quiet campsite late at night, a whisper-quiet petrol engine allows you to arrive without waking the local wildlife or fellow campers — a genuinely phenomenal benefit for wild camping.

Investment and resale

As legislation tightens, unleaded motorhome resale values are holding incredibly strong. Buyers are actively seeking out petrol models to future-proof their holidays against expanding emission zones.

Running costs, maintenance, and upgrades

Navigating the running costs of petrol motorhomes requires a slightly different approach to diesel ownership. While pump prices between petrol and diesel fluctuate, the real savings in a petrol van come from reduced maintenance complexities.

Keeping your engine healthy

If you are buying a second-hand van for a conversion, knowing how to maintain a high-mileage van engine is essential:

•      Regular oil changes: Turbocharged petrol engines require high-quality, manufacturer-approved synthetic oil. Change it every 10,000 miles to protect the turbo bearings.

•      Spark plugs: Unlike diesels, petrol engines rely on spark plugs. Ensure these are changed according to the service schedule to maintain fuel efficiency and prevent misfires.

•      Timing belts/chains: Always check the replacement intervals. A snapped cambelt on a fully loaded campervan will result in catastrophic engine failure.

Common repairs for petrol van engines often involve ignition coils, oxygen (lambda) sensors, and, occasionally, carbon build-up on direct-injection engines. However, these repairs are generally much cheaper than replacing diesel injectors or EGR (Exhaust Gas Recirculation) valves.

Electrical upgrades for petrol vans

Converting a van means installing an off-grid electrical system. Almost all modern petrol vans feature “smart alternators” designed to reduce emissions by only charging the vehicle battery when decelerating. To bypass this and charge your leisure battery while driving, you must use a DC-to-DC battery charger (such as a Victron Orion or Renogy unit) rather than an old-fashioned split charge relay. This ensures your lights, fridge and devices stay powered without draining your starter battery.

LPG conversion for cheaper fuel costs

For those concerned about the fuel costs of larger petrol engines, there is a time-tested solution: LPG (Liquid Petroleum Gas) conversion. LPG is significantly cheaper per litre than standard unleaded petrol. By installing an underslung LPG tank, you can run a large-engine petrol motorhome at a fraction of the cost — making it an incredibly economical choice for long-distance European tours.

Petrol, diesel, hybrid or electric: which motorhome should you choose?

The right choice depends less on the badge and more on how you actually travel:

Choose...	If...
Petrol campervan	You mainly take short breaks, drive into towns and cities, want a quieter engine and are buying a smaller or medium-sized van conversion.
Diesel motorhome	You cover high motorway mileage, tow regularly, carry heavy payloads or own a larger coach-built vehicle where torque and fuel economy still matter.
Petrol-hybrid campervan	You want the best compromise between urban electric driving and long-distance petrol range.
Fully electric campervan	Your trips are predictable, your payload is light, and you have reliable access to charging.

 

Looking ahead: the transition to hybrids

As we look to the late 2020s and beyond, the future of the motorhome isn’t purely petrol — it’s electrified. Because heavy leisure vehicles are currently difficult to run entirely on electric power due to battery weight and range anxiety, the industry is turning to hybrid powertrain alternatives for campers.

Plug-in Hybrid Electric Vehicles (PHEVs), such as the Ford Transit Custom PHEV, pair a highly efficient petrol engine with an electric motor and a drivable battery. This represents the ultimate sweet spot for the modern campervan enthusiast:

•      Zero-emission urban driving: Use the electric battery to navigate through strict city centres and ULEZ zones silently and for free.

•      Unlimited range: Once the battery depletes, the petrol engine kicks in, allowing you to drive into the remote Highlands or across the Alps without panic-searching for a charging point.

•      On-board power: Future hybrids promise the ability to run your campervan’s 230v appliances directly from the vehicle’s traction battery, potentially eliminating the need for a separate, heavy leisure battery altogether.

For many UK buyers, the future is likely to be petrol first, hybrid next, and fully electric later.

Frequently Asked Questions

Are petrol motorhomes ULEZ compliant?

Many petrol motorhomes and campervans are ULEZ compliant if they meet Euro 4 emissions standards or better. However, compliance depends on the exact vehicle, age, engine and registration details, so owners should always check using the TfL ULEZ checker or the GOV.UK Clean Air Zone checker before travelling into a controlled zone.

Are diesel motorhomes being banned?

Diesel motorhomes are not being banned from UK roads. However, older, non-compliant diesel vehicles may face daily charges in Clean Air Zones, Low Emission Zones or Ultra Low Emission Zones. Modern Euro 6 diesel motorhomes can still be a practical option for long-distance touring.

Is petrol better than diesel for a campervan conversion?

Petrol can be better for smaller campervan conversions, short trips, urban driving and quieter touring. Diesel can still be better for heavy loads, towing and long-distance motorway use.

Do petrol campervans use more fuel?

Historically, petrol campervans used more fuel than diesel models. Modern turbocharged petrol engines have narrowed the gap, but diesel still usually has the advantage for high-mileage motorway touring. The overall cost difference depends on fuel prices, maintenance, clean air zone charges and how often you use the vehicle.

Are petrol campervans good for Europe?

Petrol campervans can be a good option for European travel because many cities are tightening emissions rules. A compliant petrol vehicle can make urban access easier, although each country and city has its own rules, stickers and registration systems.

Will hybrid campervans replace petrol motorhomes?

Hybrid campervans are likely to become more common as they combine petrol range with electric driving for towns and cities. They may not replace petrol motorhomes immediately, but they are likely to become an important transition technology before fully electric motorhomes become practical for more owners.

Conclusion

The future of petrol motorhomes and petrol campervans is brighter — and cleaner — than ever before. Driven by stringent environmental legislation and supported by massive leaps in turbocharging technology, petrol engines are no longer the thirsty, underpowered alternative to diesel. They are now the smart, future-proof choice for many travellers.

Whether you are converting a small, agile petrol van for weekend surfing trips, or investing in a coach-built motorhome designed to navigate Europe’s tightening clean air zones, unleaded power offers a compelling mix of reliability, quiet operation and financial peace of mind. As hybrid technology continues to blend the reliability of petrol with the clean energy of electric, the open road remains as inviting as ever.
