Yardley Citgo has joined the elite group of petroleum retailers pledged to maintain top tier status.
Top tier status refers to a commitment to provide TOP TIER™ detergency formulations in all grades of Citgo branded petroleum. These detergency formulations help to prevent deposits on fuel injectors, combustion chambers, and intake valves.
Many premium car manufacturers, including BMW, Mercedes Benz and others, suggest using only top tier formulated gasoline. For more information regarding the TOP TIER™ program go to www.toptiergas.com. Also visit www.bigoakcitgo.com to learn more about Big Oak Citgo.
