I have always been partial to exxon, but they have the worst gas in my opinion. It has really gone downhill in recent years. Yet I still buy it.

I used to always buy Exxon/Mobil or Shell. After hearing about ExxonMobil's profits.. I'm through with them... and shell is just seems more expensive relative to other brands.

I picked up a tank of regular for 1.89/gal at a BP/Amoco in Roanoke, VA and then drove to my parents place near Washington, DC. Just bought gas at a Shell for 2.25.

A new class of gasoline, called TOP TIER Detergent Gasoline, is appearing at retail stations of some fuel marketers. 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.

As of August 15, 2005, the following gasoline brands meet the TOP TIER Detergent Gasoline Standards:

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.


Where Can TOP TIER Detergent Gasoline Be Purchased?
The TOP TIER program began on May 3, 2004. Some fuel marketers have already joined and have introduced TOP TIER Detergent Gasoline. This is a voluntary program and not all fuel marketers will offer this product. Once fuel marketers make public announcements, they will appear on a list of brands that meet the TOP TIER standards.


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.

Ok.....I've always been a fan of irony, so try this on.........I live in Ohio, not too far from the Honda plants. I was talking to a friend that works at one of the plants about the Top Tier Gas that some automakers are recommending. I mentioned to him that I noticed that Honda was on the list of automakers. He laughed and told me that at the Honda Service Center, they sell Marathon gas.

I can see John Belushi now............."Samurai Honda Associate"!!!

Id Chevron's on it, they need to add texaco, because they are the same company and have the same gas (both with Techron)

I've been using Quick Trip mostly. They guarantee their gas supposedly. They've been advertising they got the top tier rating for a while now. They also happen to be one of the cheapest as well. $1.93 the other day.

I have actually put my truck on a strict diet of top tier, after running into a lot of pinging issues from places like Kroger
