Top Tier Gasoline

[njbok]

I know most gasoline posts here are on the subject of octane rating - 93,
87, (premium, regular), etc.

While it's wise to follow the owners manual recommendations on octane, not
much has been said about TIER ratings. There was a time (only a couple of
years ago) when we were advised, in addition to the octane rating at the
pump, that we should only use "Tier 1" gasoline. If a station sold "Tier 1,
all octane levels there were Tier 1. The pumps actually bore the "Tier 1"
label.

Government requires that all gasoline marketed here contain a minimum
detergent level, but Tier 1 contained a more effective amount. (At least
this is what I've read, anyway.) I remember checking pumps for the Tier 1
labels in the past.

At the last few fill-ups, I've been unable to find the labels at any
brand/station I've used. Now I read that some auto manufacturers (BMW,
Maecedes, etc) and oil companies Conoco, Shell, etc,) have agreed upon a
new "Top Tier" designation for their better-than-government detergent level
gasolines. It seems the Top Tier designation has replaced "Tier 1"
designation.

If anyone knows of an off-brand (WaWa, Delta, etc) or brand-name (Hess, )
around here that is Top Tier I'd appreciate hearing about it. Thanks.

Go to http://www.toptiergas.com/retailers.html for a list of Top Tier
retailers, use the links for an explanation of Top tier fuel.

A friend is a researcher for an independent lab that formulates gasoline,
and according to him premium and top tier fuels tend to have more effective
fuel additives, although he uses regular in his Chevy.

I've found that no matter what the price difference at the pump, Shell
gas costs me less per mile to run than others around here.

And Shell 93 made a difference as far as cleaning things out to get to
that point. After that, there was no difference between 93 and 87
octane.

Hello all,



Sorry for being off topic. I didn't want to change the topic of this thread
but I just wanted to add something that is also very important. It's called
"Hot Gas" and the story originally came out in The Kansas City Star. I don't
want to get on my soapbox but I don't think that the big oil companies are
particularly interested in giving the consumer the facts or even information
on anything from motor oil standards to tier one gas and hot gas. The list
goes on.



Story here. http://www.kansascity.com/news/hot_fuel/

Several years ago we had a mechanic who was part of a race-car pit crew. He
said that they always added a can of Chevron Techtron to the gas. It kept
the injectors and valves clean . Been doing it for years and it seems to
work. Of course, I guess you could just use Chevron gas - don't know.

We also have a '87 Camero that had faulty GM fuel injectors. The owners
manual for it back then said to use Mobile gasoline. We heard that GM
agreed to recommend their gas if they would put additional detergent in it
to help keep the injectors clean in city driving conditions.

Good heavens, I should have kept my '29 Model A - it ran on anything.

So there is something to this gasahol not being good enough huh?
Gasahol probably is not a Top Teir fuel, so it will burn out a Lexus
engine which needs only Top Teir fuels. Wish they would say that in
the direction encycolpedia instead of putting all those confusing
weasel words around the topic.
