Top Tier Detergent Gasoline
All gasoline is not created equal. That's why in 2004 BMW, GM, Honda and Toyota established the Top Tier program. It's a quality standard that defines detergency levels in gasoline higher than those currently set by the EPA; a standard that Chevron gasolines with Techron were the first designated to meet out of all U.S. gasoline retailers.
In fact, unlike some other gasoline retailers who actually had to change their formulation, Chevron did not have to change its Techron formulation to meet the Top Tier standard. Top Tier designated gasolines like Chevron with Techron keep vital engine parts cleaner than lower quality fuel by reducing harmful deposits, resulting in better performance and lower emissions.
