When auto manufacturers design and build a new engine and emissions control system, they know they must prove to the United States Environmental Protection Agency (EPA) that the car can go a long way and still operate with very low emissions. That’s why all three major U.S. auto manufacturers use Chevron with Techron to help their new engines pass the tough EPA emission system durability tests which now are up to 120,000 miles long. They buy and use Chevron, even though they must purchase it in Kentucky and pay to truck it all the way to the Detroit area, because Chevron does not market gasoline anywhere near Michigan.
Chevron with Techron was also the first gasoline to be designated as a TOP TIER Detergent Gasoline by BMW, General Motors, Honda and Toyota in the US and Canada.
