Availability
In 2004 the standard was adopted by ten gasoline distributors. Chevron and QuikTrip were first, followed that same year by 76 Stations, Conoco, Phillips 66, Road Ranger, Kwik Trip, Shell, Entec Stations, and MFA Oil Company. Since then 20 more gasoline distributors have met the proprietary standard and Top Tier gasoline can now be found in gas stations all over the U.S. and Canada. In the U.S, Aloha Petroleum, CountryMark, Exxon, Mobil, Hawaii Fuelling Network (HFN), Holiday Stationstores, Kwik Star, Ohana Fuels, Mileage Stations, Rebel Oil, Severson Oil, Texaco, Tri-Par Oil Company, USA, and US Oil now offer Top Tier gasoline. In Canada, Chevron Canada, Petro Canada, Shell Canada, and most recently Esso have attained the designation. Meeting this standard allows gasoline marketers to differentiate themselves from their competition. All stations selling the brand must meet Top Tier standards before the brand is qualified.
Not all gasolines with higher levels of detergents have elected to join Top Tier. For example, BP, which is not listed as a Top Tier gas, was named in a media report as having detergent levels comparable to two Top Tier gasoline marketers.
A previous standard used was the BMW Unlimited Mileage Test. BP claims to meet this. BMW now mentions Top Tier gas in its owner's manuals but not the unlimited mileage test.

Famous quotes containing the word availability:
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
