Understanding Your RV Fuel: Gasoline vs. Diesel

The first step in mastering RV fuel is knowing what powers your home on wheels. Most RVs run on either gasoline or diesel. Each has distinct characteristics, benefits, and considerations for the careful traveler.

Gasoline RVs: What You Need to Know

Many Class A, B, and C motorhomes, especially older models and smaller units, run on gasoline. These engines are often familiar to drivers, resembling those found in large trucks or SUVs.

  • Accessibility: Gasoline is widely available at almost every gas station. You won’t struggle to find a pump.
  • Initial Cost: Gasoline RVs typically have a lower purchase price than their diesel counterparts.
  • Maintenance: Maintenance can be simpler and less expensive, as parts and mechanics are more common.

However, gasoline engines often offer lower fuel efficiency compared to diesel, especially under heavy loads. Pay attention to the recommended octane level for your specific engine.

Diesel RVs: Power and Longevity

Diesel RVs, often found in larger Class A motorhomes (sometimes called “diesel pushers”) and some heavy-duty trucks, are renowned for their power and durability. They use diesel fuel, which has a higher energy density than gasoline.

  • Torque and Power: Diesel engines excel at towing and climbing steep grades, making them ideal for heavy RVs.
  • Fuel Efficiency: Generally, diesel engines offer better mileage, especially on highways, which can offset the higher fuel cost over long distances.
  • Longevity: Diesel engines are built to last, often reaching hundreds of thousands of miles with proper care.

Diesel fuel prices can fluctuate more than gasoline, and not all gas stations have diesel pumps accessible for large RVs. You’ll also encounter Diesel Exhaust Fluid (DEF) in newer diesel engines, which reduces emissions.

Propane (LPG) for RV Systems: Beyond Propulsion

While not a primary propulsion RV fuel, propane (LPG) is crucial for almost every RV. It powers many of your onboard systems, making your RV a comfortable living space.

  • Appliances: Your refrigerator, water heater, furnace, and stove often run on propane.
  • Generators: Some RVs have propane-powered generators for off-grid electricity.
  • Availability: Propane is widely available at RV parks, hardware stores, and designated filling stations.

Always ensure your propane tanks are properly secured and regularly inspected. Understanding your propane consumption is key to managing your comfort while boondocking or dry camping.

Maximizing RV Fuel Efficiency: Smart Tips for the Road

One of the biggest concerns for RVers is fuel cost. Fortunately, there are many proactive steps you can take to significantly improve your RV fuel efficiency. These rv fuel tips will help you stretch every gallon.

Driving Habits that Save Fuel

Your driving style has a huge impact on how much fuel your RV consumes. Small changes can lead to big savings.

  • Maintain a Consistent Speed: Avoid rapid acceleration and hard braking. Use cruise control on flat terrain.
  • Reduce Speed: Fuel economy drops significantly at higher speeds. Aim for 55-65 mph, depending on your RV’s sweet spot.
  • Anticipate Traffic: Look far ahead to avoid unnecessary stops and starts. Coasting when possible saves fuel.

Think of your RV as a big, heavy vehicle. Gentle inputs are always better for both fuel economy and overall wear and tear.

RV Maintenance for Optimal Fuel Economy

A well-maintained RV is an efficient RV. Regular upkeep is one of the best rv fuel best practices you can adopt.

  • Tire Pressure: Check your tire pressure regularly before each trip. Underinflated tires increase rolling resistance and reduce fuel economy. Use the pressure recommended by your RV manufacturer, not just what’s on the tire sidewall.
  • Engine Tune-Up: Follow your manufacturer’s recommended service schedule. A well-tuned engine runs more efficiently.
  • Air Filters: A clogged air filter restricts airflow, forcing your engine to work harder. Replace it as recommended.

Don’t skip those routine checks. They pay off in fuel savings and prevent costly breakdowns.

Weight Management and Aerodynamics

Your RV’s weight and how it cuts through the air are major factors in fuel consumption.

  • Pack Light: Only bring what you truly need. Every extra pound your RV carries requires more fuel to move.
  • Distribute Weight Evenly: Proper weight distribution improves handling and can reduce strain on your engine.
  • Reduce Drag: Close windows, roof vents, and awnings when driving at highway speeds. Remove any unnecessary exterior attachments that create drag.

Even small aerodynamic improvements can make a difference over hundreds or thousands of miles.

Common Problems with RV Fuel and How to Avoid Them

Understanding potential pitfalls with RV fuel can save you headaches and expensive repairs. Being proactive with your rv fuel care guide is essential.

Fuel Contamination and Storage Issues

Fuel quality is paramount, especially for RVs that might sit for periods. Contaminated or stale fuel can cause serious engine problems.

  • Water Contamination: Water can enter fuel tanks through condensation or faulty seals. It can lead to rust and engine damage.
  • Microbial Growth (Diesel): Diesel fuel can develop “algae” (microbial growth) which clogs filters and fuel lines.
  • Stale Fuel: Gasoline degrades over time, especially if ethanol-blended. This can gum up carburetors and fuel injectors.

Always fill up at reputable, high-volume stations to ensure fresh fuel. Consider a fuel stabilizer if your RV will be stored for more than a month or two.

Choosing the Right Octane/Cetane

Using the incorrect fuel type or grade can harm your engine and reduce performance.

  • Gasoline Octane: Most gasoline RVs run perfectly fine on regular (87 octane) fuel. Check your owner’s manual. Higher octane is usually only needed if your engine is designed for it, or if you experience “knocking” or “pinging.”
  • Diesel Cetane: Cetane rating for diesel fuel indicates its ignition quality. Most diesel engines perform well with a cetane rating of 40-55. Higher cetane can improve cold starting and reduce engine noise.

When in doubt, always refer to your RV’s owner’s manual. It’s your ultimate guide for proper fuel selection.

Running Out of Fuel: Prevention and Recovery

Running out of fuel in an RV, especially in a remote area, is more than an inconvenience; it can be a safety hazard. This is a common problem with RV fuel that is easily avoidable.

  • Monitor Your Gauge: Don’t let your fuel tank get below a quarter full, especially when traveling through unknown territory.
  • Plan Your Stops: Use apps like GasBuddy, Love’s Connect, or Pilot Flying J to locate RV-friendly fuel stations along your route.
  • Carry a Reserve: For longer trips or off-grid adventures, consider carrying a small, legally approved auxiliary fuel tank. Always store it safely outside the living area.

If you do run out, safely pull over, activate your hazard lights, and call for roadside assistance. Do not attempt to walk long distances for fuel, especially on busy highways.
