Since the minimum additive performance standards were first established by the EPA in 1995, most gasoline marketers have actually reduced the concentration level of detergent additive in their gasoline by up to 50%. As a result, the ability of a vehicle to maintain stringent Tier 2 emission standards has been hampered, leading to engine deposits that can have a big impact on in-use emissions and driver satisfaction.
Eight top automakers have raised the bar. TOP TIER™ Detergent Gasoline helps drivers avoid lower quality gasoline which can leave deposits on critical engine parts, reducing engine performance. That's something drivers and automakers can get behind.
Gasoline retailers must meet the high TOP TIER™ standards with all grades of gasoline to be approved by the automakers as providing TOP TIER™ Detergent Gasoline.
In addition, all gasoline outlets carrying the brand of the approved retailer must meet the TOP TIER™ standards.
Additional gasoline brands are added to the TOP TIER™ list as they meet the standards.
