10 Underwhelming Gasoline Brands to Avoid

When it comes to filling up your car, the choice of gasoline can do more than just get you from point A to point B. Not all gas stations offer the same quality fuel, and choosing poorly could lead to problems under the hood. In this article, we explore a selection of gasoline brands that have frequently drawn criticism from consumers. From issues with fuel consistency to adverse effects on engine performance, we’ll shed light on why these brands might not be the optimal choice for your vehicle.

Murphy USA

Murphy USA often attracts customers with its competitive pricing, largely due to its strategic locations near Walmart stores. Despite its affordability, some customers have raised concerns about fuel consistency, reporting problems like rough idling, occasional misfires, and poorer-than-expected fuel economy. These issues are particularly noted in regions where the turnover of gasoline stock is slower, leading to potential stale fuel that might not perform optimally in sensitive or high-performance engines.

Pilot Flying J

As a significant provider of fuel, especially for commercial vehicles and trucks, Pilot Flying J plays an essential role in the logistics and transportation industry. While they offer convenient refueling options across North America, there have been reports of inconsistent fuel quality. Some customers mention specific instances where the gasoline seemed to degrade vehicle performance, leading to lower mileage and increased engine strain, which could accelerate wear and tear if the fuel used continuously lacks certain quality standards.

BP

BP, with its global presence, adheres to generally high standards of fuel quality, which include additives meant to clean the engine and improve efficiency. However, instances of fuel contamination have been reported, which can lead to serious issues like engine knocking, damage to fuel injectors, or a decrease in overall engine performance. These incidents, while not widespread, highlight potential lapses in quality control that can affect vehicle reliability.

Circle K

Circle K sources its fuel from various suppliers, which might lead to inconsistencies in fuel quality across different stations. Consumers have occasionally noted that such inconsistencies can adversely affect their vehicle’s performance, especially in terms of engine response and fuel efficiency. In some cases, drivers with older or more finely-tuned vehicles have reported needing more frequent maintenance when regularly using this fuel.

Safeway

Although primarily a supermarket chain, Safeway also offers gasoline, which includes competitive pricing similar to other grocery-based fuel stations. However, there are concerns about the effectiveness of the additives used in their gasoline, with some customers suggesting that these do not provide the same level of engine cleaning and protection as more established, premium gasoline brands. This could lead to build-ups in the engine and fuel system, potentially reducing the longevity and efficiency of the vehicle.

Speedway

Speedway is popular for its convenience and competitive fuel prices, but it has received mixed reviews regarding the long-term benefits of its gasoline. Specific feedback includes concerns about lower miles per gallon and the potential for increased residue accumulation in the engine, which can lead to higher costs in engine maintenance and reduced overall vehicle health over time.

Sam’s Club

As a members-only outlet, Sam’s Club offers gasoline at lower prices, which is a significant draw for consumers. However, some members report that the lower price can be indicative of compromised fuel quality, which might manifest as engine misfiring, reduced efficiency, and occasional difficulties during cold starts, suggesting that the gasoline may not be as refined or additive-rich as other higher-priced options.

ARCO

ARCO is known for its economical fuel prices but has faced scrutiny over whether its cost-cutting affects fuel quality. Some consumers believe that the cheaper price points reflect a lower standard in the gasoline’s additive mixture, potentially leading to less effective cleaning capabilities and a higher likelihood of deposit accumulation within the engine, which could impair long-term vehicle performance.

Valero

Valero generally maintains a solid reputation, but it has not been immune to criticism regarding fuel consistency. Issues reported by consumers include fuel-related anomalies like clogged fuel filters and occasional engine knocking, particularly in older vehicles that are more susceptible to fuel variances. These issues suggest occasional lapses in fuel processing or additive formulation.

Sunoco

While Sunoco offers fuels that cater to a range of needs, including high-performance racing fuels, general consumer gasoline has received mixed feedback. Some drivers report inconsistencies that affect their vehicle’s smoothness and responsiveness. Although these cases are not universally applicable, they reflect a variability that can impact consumer satisfaction and vehicle performance.
