Avoiding Fuel Mix-Ups for RVers: Lessons from the St. Clairsville Sam's Club Incident

On a recent weekend in St. Clairsville, Ohio, a fuel mix-up at a Sam’s Club gas station left numerous drivers, including potential RVers, stranded with vehicles that wouldn’t start. According to reports from WTRF, a third-party fuel supplier mistakenly mixed fuel grades during a refill, causing diesel to be pumped into vehicles expecting gasoline.

This incident, which gained attention after frustrated customers voiced their complaints on social media, serves as a stark reminder of the importance of fuel vigilance for all drivers, particularly those in the RV community. For RVers, whose vehicles are often their homes on wheels, such mishaps can be more than an inconvenience—they can derail entire trips and lead to costly repairs.

This article explores the St. Clairsville incident, its implications for RVers, and practical advice to avoid similar fuel-related disasters.

The St. Clairsville Fuel Fiasco: What Happened?

The incident at the Sam’s Club in St. Clairsville unfolded when a third-party fuel supplier inadvertently mixed diesel with gasoline during a routine tank refill. Unaware of the issue, the retailer continued to dispense the contaminated fuel, leading to a cascade of problems for unsuspecting drivers.

Customers began noticing issues when their vehicles, including a nearly new truck with fewer than 1,000 miles, failed to start after filling up. Social media posts highlighted the frustration, with one woman describing how her brother-in-law’s truck was left stranded in her driveway, requiring towing and repairs.

The incident not only caused immediate inconvenience but also raised concerns about potential engine damage and the associated costs.

Jerry Witzberger, owner of ASAP Auto Care, explained to WTRF that diesel fuel, which is significantly thicker than gasoline, can wreak havoc on gasoline engines. “Hopefully, it didn’t get through the whole system,” he noted, adding that affected vehicles would likely need their fuel systems flushed—a process that, while often salvageable, can be expensive.

Sam’s Club responded by acknowledging the issue and encouraging affected customers to file claims, but the exact number of impacted vehicles remains unclear.

For RVers, this incident hits close to home. Many RV owners rely on gasoline-powered tow vehicles or diesel-powered motorhomes, and a fuel mix-up can lead to significant disruptions, especially when traveling far from home. The costs of towing, repairs, and potential trip cancellations can quickly add up, making it critical for RVers to understand how to prevent such issues.

Why Fuel Mix-Ups Are a Big Deal for RVers

RVs, whether towable trailers or self-contained motorhomes, are complex vehicles that often require specific fuel types to operate efficiently. Class A motorhomes, for instance, are commonly diesel-powered, while many tow vehicles and smaller RVs run on gasoline. A fuel mix-up—such as pumping diesel into a gasoline engine or vice versa—can cause severe mechanical issues.

Diesel in a gasoline engine can clog fuel injectors, damage spark plugs, and lead to engine shutdown, while gasoline in a diesel engine can cause poor combustion and potential damage to fuel pumps and injectors.

For RVers, the stakes are higher than for the average driver. A breakdown in a remote location can strand you far from repair facilities, disrupt travel plans, and lead to significant expenses. Additionally, RVs are often used for extended trips, meaning a fuel-related issue could leave you without access to your temporary home. The St. Clairsville incident underscores the importance of proactive measures to ensure you’re fueling your RV correctly.

How to Avoid Fuel Mix-Ups: Practical Tips for RVers

To help RVers steer clear of fuel-related mishaps, here are actionable tips to ensure you’re pumping the right fuel every time:

1. Know Your RV’s Fuel Requirements

Before hitting the road, familiarize yourself with the fuel type required for your RV or tow vehicle. Check the owner’s manual and look for labels near the fuel cap, which often indicate “Gasoline Only” or “Diesel Only.” If you’re new to RVing or renting a vehicle, confirm the fuel type with the dealer or rental agency. For example:

Gasoline RVs: Most Class B and Class C motorhomes, as well as many tow vehicles, use unleaded gasoline.
Diesel RVs: Many Class A motorhomes and some heavy-duty tow vehicles (like diesel trucks) require diesel fuel.

Keep a note of your vehicle’s fuel type in an easily accessible place, such as a sticker inside the fuel door or a reminder in your RV’s dashboard.

2. Double-Check Fuel Pumps Before Filling

Fuel pumps at gas stations are typically color-coded, but mistakes can happen, as seen in St. Clairsville. To avoid errors:

Verify the pump label: Ensure the pump is labeled for the correct fuel type (e.g., “Unleaded Gasoline” or “Diesel”).
Check the nozzle color: In the U.S., diesel nozzles are often green, while gasoline nozzles are typically black or silver. However, this isn’t universal, so don’t rely solely on color.
Look for signs of tampering or mislabeling: If a pump looks suspicious or the label is unclear, choose another pump or station.

If you’re at a busy station, take a moment to confirm you’re at the correct pump before inserting the nozzle.

3. Use Reputable Fuel Stations

While the St. Clairsville incident occurred at a well-known retailer, choosing reputable fuel stations can reduce the risk of mix-ups. Opt for stations with high turnover, such as those near highways or popular RV destinations, as they’re more likely to have fresh fuel and well-maintained pumps. Avoid lesser-known stations in remote areas if possible, as they may have older equipment or less frequent oversight.

For RVers, truck stops like Pilot Flying J or Love’s are often a good choice, as they cater to diesel-powered vehicles and typically have dedicated diesel pumps. These stations also offer amenities like RV dump stations and larger parking areas, making them convenient for RV travelers.

4. Be Cautious at Unfamiliar Stations

When traveling, you may encounter unfamiliar gas stations, especially in rural areas. To minimize risks:

Ask locals or fellow RVers: If you’re unsure about a station’s reliability, check online reviews or ask for recommendations at RV parks or campgrounds.
Inspect the pump: Look for signs of wear, damage, or outdated equipment, which could indicate poor maintenance.
Start with a small fill: If you’re unsure about a station, pump a small amount of fuel (e.g., 5 gallons) and monitor your vehicle’s performance before filling the tank completely.

5. Educate Your Travel Companions

If you’re traveling with family or friends who may assist with fueling, ensure they know the correct fuel type for your RV. A simple miscommunication can lead to the wrong fuel being pumped. Consider labeling the fuel cap with a clear marker, such as “DIESEL ONLY” or “GASOLINE ONLY,” to avoid confusion.

6. Monitor Your Vehicle After Fueling

After filling up, pay attention to how your RV or tow vehicle performs. Signs of a fuel mix-up include:

Difficulty starting the engine
Unusual engine noises or sputtering
Reduced power or acceleration
Smoke or unusual exhaust odors

If you suspect a problem, stop driving immediately to avoid further damage. Contact a mechanic or roadside assistance, and inform the gas station of the issue. In the St. Clairsville case, customers reported issues on social media, which prompted Sam’s Club to investigate. Document your experience, including receipts and photos of the pump, to support any claims.

7. Invest in Roadside Assistance

For RVers, a roadside assistance plan tailored to RV travel is a lifesaver. Services like Good Sam Roadside Assistance or AAA RV Plus offer towing, fuel delivery, and other support for large vehicles. In the event of a fuel mix-up, these services can help transport your RV to a repair shop. Ensure your plan covers the size and weight of your RV, as standard plans may not accommodate larger vehicles.

8. File Claims Promptly

If you’re affected by a fuel mix-up, contact the gas station or retailer immediately to report the issue. In the St. Clairsville incident, Sam’s Club encouraged affected customers to file claims directly with the club. Keep detailed records, including:

Fuel purchase receipt
Photos of the pump and vehicle
Repair estimates or invoices
Towing receipts

These documents will strengthen your case for reimbursement or compensation.

What to Do If You’ve Pumped the Wrong Fuel

If you realize you’ve pumped the wrong fuel, don’t start the engine. Starting the vehicle can circulate the incorrect fuel through the system, increasing the risk of damage. Instead:

Turn off the ignition: If the engine hasn’t been started, keep it off.
Contact the gas station: Inform the station manager of the issue and ask them to inspect the pump.
Arrange for towing: Have your RV or tow vehicle towed to a mechanic for fuel system flushing.
Notify your insurance: Some insurance policies cover fuel mix-up repairs, so check with your provider.
Document everything: Keep records of all communications and expenses for potential claims.

As Jerry Witzberger noted, most engines can be salvaged after a fuel mix-up, but the process can be costly, especially for RVs with larger fuel systems. Acting quickly can minimize damage and expenses.

Lessons from St. Clairsville for the RV Community

The St. Clairsville incident highlights the importance of vigilance when fueling your RV. While third-party errors are rare, they can have significant consequences for RVers, who rely on their vehicles for both transportation and accommodation. By knowing your RV’s fuel requirements, double-checking pumps, choosing reputable stations, and monitoring vehicle performance, you can reduce the risk of a fuel mix-up derailing your adventure.

Additionally, the incident underscores the power of community communication. Social media posts from affected drivers prompted Sam’s Club to address the issue quickly, demonstrating how RVers can use platforms like X or RV forums to share warnings and advice. Joining RV communities, whether online or at campgrounds, can provide valuable insights into safe fueling practices and reliable stations along your route.
