When you purchase gasoline at an Esso- and Mobil-branded gas station, you’re fueling with advanced Synergy gasoline. Engineered with 7 key ingredients to help improve fuel economy,** Synergy gasolines provide lower emissions and improved engine responsiveness** and are designed to provide corrosion protection and improved performance compared with gasolines meeting minimum government detergency standards. In addition, Synergy gasoline contains significantly higher detergent levels than CGSB requirements and has passed a series of deposit control performance tests.
**Improvements, such as fuel economy, are based on Synergy-branded gasoline, where and when available, compared to gasoline meeting minimum Canadian government detergency standards. Actual benefits will vary depending on factors such as vehicle type, driving style, and gasoline previously used.
