What Marathon's Secret Shopper Program Can Teach Retailers About Customer Loyalty
By Christy Cody, Business Development, Siarc Oil
In the fuel retail industry, attracting customers is important—but keeping them coming back is what drives long-term success.
As a Business Development professional for Siarc Oil and a partner to Marathon-branded retailers throughout Louisiana, I regularly discuss customer loyalty, operational excellence, and profitability with store owners and operators. One of the most valuable tools available to retailers is often viewed as simply a compliance requirement: the Marathon Secret Shopper Program.
At Siarc Oil, we believe the Secret Shopper Program is much more than a scorecard. It's a window into the customer experience and an opportunity to identify improvements that can strengthen customer loyalty and support business growth.
Seeing Your Store Through Your Customers' Eyes
Every day, customers make decisions about where to stop for fuel, convenience items, food, and beverages. Often, those decisions come down to more than price.
Customers notice:
Whether the fuel island is clean
If pumps are working properly
Whether the store is well-stocked
How employees interact with them
The condition of restrooms
Overall cleanliness and appearance
The Marathon Secret Shopper Program evaluates many of these same areas, providing retailers with valuable insight into how customers experience their location.
At Siarc Oil, we encourage our customers to look beyond the final score and focus on the story behind the evaluation.
Turning Insights Into Improvements
A Secret Shopper report can reveal opportunities that might otherwise go unnoticed.
For example, recurring comments about:
Store presentation
Fuel island cleanliness
Signage visibility
Customer service
Product availability
can help retailers prioritize operational improvements that directly impact customer satisfaction.
Small adjustments often create meaningful results. Something as simple as improving pump appearance, increasing attention to store cleanliness, or enhancing employee engagement can influence whether a customer chooses to return.
Customer Loyalty Is Built Through Consistency
One of the most important lessons Secret Shopper evaluations reinforce is the value of consistency.
Customers want to know what to expect every time they visit your location.
They expect:
Fuel availability
Clean facilities
Friendly service
Safe environments
Efficient transactions
When these expectations are consistently met, trust is built. Trust leads to repeat visits, increased in-store purchases, and stronger customer loyalty.
The retailers who consistently perform well are often the retailers who focus on delivering the same positive experience every day.
Using Trends to Drive Long-Term Success
At Siarc Oil, we encourage retailers to view Secret Shopper evaluations as part of a larger performance strategy.
One report provides a snapshot. Multiple reports reveal trends.
By reviewing results over time, retailers can identify recurring strengths and opportunities, allowing them to make informed decisions about operations, staffing, maintenance, and customer service.
To further support our Marathon-branded retailers, Siarc Oil conducts complimentary monthly site assessments. These proactive visits allow our team to identify potential concerns or areas for improvement before they impact the customer experience or Secret Shopper performance. By working collaboratively with store owners and managers, we can address operational opportunities early, reinforce brand standards, and help create a consistently positive experience for every customer who visits the location.
This proactive approach helps transform both Secret Shopper feedback and our complimentary site assessments into a continuous improvement process rather than a one-time evaluation.

Every Customer Visit Matters
In today's competitive marketplace, customer loyalty isn't earned through one exceptional experience. It's earned through hundreds of positive interactions over time.
The Marathon Secret Shopper Program helps retailers understand how effectively they are delivering those experiences.
At Siarc Oil, we believe the greatest value of the program isn't the score itself—it's the opportunity to learn, improve, and create a better experience for every customer who visits your location.
By combining Marathon's Secret Shopper insights with our complimentary monthly site assessments, we help retailers stay ahead of potential issues, protect their brand reputation, and create the kind of consistent customer experience that builds lasting loyalty.
Because when customers know they can count on your store, they're far more likely to return.
And in retail, there is no greater measure of success than a customer who chooses to come back.
Reliable Energy Starts Here.
