When planning a road trip or considering the rent of a motorhome, one of the essential factors to consider is the gas mileage, also known as miles per gallon (MPG). This metric indicates how far your motorhome can travel on a single gallon of gas, directly impacting your travel budget.
Average MPG by Motorhome Class
Class A Motorhomes: These are the largest, resembling buses and offering luxurious accommodations. Due to their size, they are less fuel-efficient, with an average MPG of 6-8. They typically have large fuel tanks ranging from 70 to over 100 gallons.
Class B Motorhomes (Campervans): These are the smallest and most maneuverable motorhomes, ideal for tight spaces. They offer the best fuel efficiency among motorhomes, with an average of 15-18 MPG. Their fuel tanks usually hold about 25 gallons. If you're planning an adventure in Iceland, consider renting a campervan to explore the island efficiently and comfortably.

Class C Motorhomes: A middle ground between Class A and B, built on a van frame or truck chassis, these motorhomes provide better fuel efficiency than Class A with an average of 10-14 MPG and fuel tank capacity ranging from 30 to 70 gallons.
Factors influencing gas mileage
Weight: Heavier motorhomes consume more fuel.
Speed: Maintaining an optimal speed of 55-60 mph maximizes fuel efficiency.
Maintenance: Regular maintenance such as tune-ups and timely oil changes can improve gas mileage.
Driving style: Smooth driving without frequent stops and starts can significantly enhance MPG.
Aerodynamics: The shape of the motorhome can affect wind resistance and fuel consumption.
Road conditions: Flat roads improve fuel economy compared to steep or winding routes.
Tips for maximizing your RV's MPG
1. Choose a Fuel-Efficient RV
Opting for a motorhome known for its fuel efficiency can significantly reduce your fuel costs over the life of the vehicle. When selecting an RV, consider:
Class B Motorhomes: Known as campervans, they typically offer the best fuel economy, making them ideal for travelers who prioritize efficiency.
Diesel Engines: Diesel-powered RVs often provide better mileage compared to their gasoline counterparts.
Newer Models: Manufacturers are continuously improving fuel efficiency. Choosing a recent model may yield better MPG due to advancements in engine technology and aerodynamics.
2. Keep the RV well-maintained
Regular maintenance is crucial in preventing fuel inefficiency caused by underperforming engines or other mechanical issues. Key maintenance tasks include:
Regular oil changes: Use the manufacturer-recommended grade of oil; this can improve gas mileage by 1-2%.
Tire pressure: Ensure tires are properly inflated as under-inflated tires can lower gas mileage by about 0.2% for every 1 psi drop in the average pressure of all tires.
Air filters: Replace old air filters. A clean air filter can improve gas mileage by up to 10% by allowing the engine to breathe better.
Regular Check-Ups: Schedule check-ups to address any mechanical issues before they become serious.
3. Plan your route
Strategically planning your travel route can lead to substantial fuel savings:
Avoid heavy traffic: Use navigation tools to avoid traffic-heavy areas, especially during peak times.
Choose flat terrain: Routes with less elevation gain are preferable as climbing hills consumes more fuel.
Use RV-Specific GPS: Some GPS systems are designed for RVs and can direct you along routes that are optimized for larger vehicles, avoiding roads with height and weight restrictions. Additionally, to ensure you never run low on fuel, check out this comprehensive guide to gas stations in Iceland, which will help you plan your refueling stops efficiently and avoid any fuel-related inconveniences during your trip.
4. Monitor your speed
Speed control is a straightforward yet effective method for conserving fuel:
Optimal speed: Driving at 55-60 mph can maximize your MPG as higher speeds generally increase wind resistance, which reduces fuel efficiency.
Use cruise control: On highways, using cruise control can help maintain a constant speed, reducing fuel consumption.
5. Pack light
The weight of your RV affects fuel consumption significantly:
Limit luggage: Only pack campervan essentials and consider the weight of optional extras.
Water weight: Travel with a partially filled water tank if full capacity isn't necessary for the journey. Water is heavy, and carrying excess can impact fuel efficiency.
Tow smartly: If towing a vehicle or trailer, make sure it's within the RV’s towing capacity and that the tow setup is optimized for aerodynamics.
Implementing these tips can lead to improved MPG, which not only saves money but also reduces the environmental impact of your travels. By focusing on fuel efficiency, you can extend the range of your adventures while keeping operating costs low.
6. Understand Gasoline Prices in Iceland
Gasoline prices in Iceland can be significantly higher than what you might be used to, due to various factors including transportation costs and taxes. Being aware of the current fuel prices can help you budget more accurately for your trip.
How many miles per gallon does an RV get?
The fuel efficiency of an RV can vary significantly depending on several factors, including the type and size of the RV, driving conditions, and the terrain. Here’s a detailed breakdown:
Class A Motorhomes: These are the largest and heaviest RVs, often resembling buses. They typically achieve between 6 to 10 miles per gallon (MPG). Their size and weight contribute to lower fuel efficiency, but they offer the most space and amenities.
Class B Motorhomes: Also known as campervans, these are the smallest and most fuel-efficient type of motorhome. They generally achieve between 18 to 25 MPG due to their smaller size and lighter weight.
Class C Motorhomes: These mid-sized motorhomes, built on a truck or van chassis, offer a balance between space and fuel efficiency. They usually get between 10 to 14 MPG.
Driving Conditions and Terrain: The fuel efficiency can be affected by driving habits, road conditions, and the terrain. For example, driving uphill, in windy conditions, or at higher speeds can reduce fuel efficiency. Conversely, steady, moderate-speed driving on flat terrain can improve MPG.
Maintenance and Load: Keeping your RV well-maintained, including regular engine checks and tire inflation, can help optimize fuel efficiency. Additionally, the weight of the load you carry can affect MPG; heavier loads will decrease fuel efficiency.
