Sounds like it really is worth the extra cost for the good stuff. There is some interesting info on that web page though. I would like to know more about this though. Perhaps a press release from Toyota, BMW, etc on this.
A new class of gasoline, called Top Tier Detergent Gasoline, will be appearing at retail stations of some fuel marketers, including Chevron, QuikTrip and now ConocoPhillips who markets under Conoco, Phillips 66 and 76 brands. This gasoline meets detergency standards developed by four automotive companies. A description of the concept and benefits of Top Tier is provided in the following question and answer section.
What is Top Tier Detergent Gasoline?
Top Tier Detergent Gasoline is a new class of gasoline with enhanced detergency. It meets new, voluntary deposit control standards developed by four automotive companies that exceed the detergent requirements imposed by the EPA.
Who developed Top Tier Detergent Gasoline standards?
Top Tier Detergent Gasoline standards were developed by four automotive companies: BMW, General Motors, Honda and Toyota.
Why was Top Tier Detergent Gasoline developed?
Top Tier Detergent Gasoline was developed to increase the level of detergent additive in gasoline. The EPA requires that all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines clean. In order to meet Top Tier Detergent Gasoline standards, a higher level of detergent is needed than what is required by the EPA. Also, Top Tier was developed to give fuel marketers the opportunity to differentiate their product.
Why did the four automotive companies join together to develop Top Tier?
All four corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency is an issue of concern to several automotive companies.
What are the benefits of Top Tier Detergent Gasoline?
Top Tier Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" set by the EPA. Clean engines help provide optimal fuel economy and performance and reduced emissions. Also, use of Top Tier Detergent Gasoline will help reduce deposit related concerns.
Who should use Top Tier Detergent Gasoline?
All vehicles will benefit from using Top Tier Detergent Gasoline over gasoline containing the "Lowest Additive Concentration" set by the EPA. Those vehicles that have experienced deposit related concerns may especially benefit from use of Top Tier Detergent Gasoline.
Where can Top Tier Detergent Gasoline be purchased?
The Top Tier program began on May 3, 2004. Chevron, QuikTrip and ConocoPhillips have met the Top Tier Detergent Gasoline standards and are offering this product in all octane grades and in all their respective marketing areas.

If the stuff costs more, ends up polluting ground water, is carcinogenic, reduces engine power and somehow damages older car systems, then you can bet CARB had a hand in it.
