Top Tier Fuel

There is an article/column in the latest (August) Car and Driver by
Larry Webster, on a new fuel certification program. Very interesting.

Following is from a recent GM TSB:

Subject:
Top Tier Detergent Gasoline (Deposits, Fuel Economy, No Start, Power,
Performance, Stall Concerns)

Models:
2005 and Prior All General Motors Passenger Cars and Trucks (U.S. Only)
2003-2005 HUMMER H2

This bulletin is being revised to identify the gasoline brands that
currently meet the Top Tier Detergent Gasoline Standards. Please
discard Corporate Bulletin Number 04-06-04-047 (Section 06 - Engine).

A new class of gasoline, called Top Tier Detergent Gasoline, will be
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.

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 loin 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. 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.

Gasoline Brands That Currently Meet Top Tier Detergent Gasoline

Detergent Gasoline Standards:

Yeah, and this is from www.toptiergas.com/deposit_control.htm :

===
The base fuel [...] shall contain denatured ethanol such that the actual
ethanol content is no less than 8.0 and no more than 10.0 volume percent.
===

So, whatever other aspects this Top Tier program has, it is also quite
apparently yet one more marketing ploy by Archer Daniels Midland to get
wider use of ethanol-diluted gasoline and less complaining about it.

Guess that means my gas station will have four grades now:
Regular (Not Cheap)
Intermediate(Not too expensive)
Super (Expensive)
Top Tier (Very Expensive)

My, my those automotive companies are much closer than we thought. I'm
positively titillated at the thought of them loining together in
public.

Is this a real problem?

So far not exactly an overwhelming success. Maybe a solution looking
for a problem to solve?

I am confused. Chevron claims they meet the Top Teir requirements in
all grades and they don't have ethanol in their gas. So what am I
missing? Is the ethanol added just for the test?

It is a little less than clearly written, but it reads to me as if Top
Tier fuel *must* contain ethanol.

I read it that way too, but Chevron doesn't show ethanol in their fuels, so
something is confusing. I actaully buy Chevron locally, but I have never
seen any advertisements at the local stations that mention Top Teir fuel. If
it is "Top Teir" then it is not affecting the cost. The Chevron station I
visit is usually competitive with anything but the bottom rung stations
(less than no name gas).

I don't know the truth to it, but I saw a report on the evening local
news a few months ago that Chevron was going to try competative pricing
and just make a few cents less profit per gallon, but increase volume
enough to make up the difference.

It looks like from what I've seen locally (San Diego) to be working,
every time I pull into a Chevron station 75% of the pumps (at least)
are full.

I normally only buy gas from Chevron and Shell, but neither's prices
are any higher than the nearest Arco. It's worth an extra block or two
to avoid that crap.
