Found this interesting. According to AAA, not all gas is the same:

I've always used top tier gas but never saw any independent testing until this.

[Infamouscrew02]

Why do all the testing and show the results of top tier verses non top tier and then not provide what products were used for testing? The local Shell is going to differ from BP? What about my local Quick Trip?

All 3 of those bands are TT. I'm assuming they found little to no difference among top tier gas brands so that's why they just gave a blanket endorsement of any TT is better than all non-TT.

I am surprised by the results as well. 19X more build up?

CITGO... top tier? Didn't know that.

Sunoco not top tier?

I think a good test and the first independent test I have seen.

When you read the test it is mostly looking at intake valve deposits on a port injected engine. I wouldn't expect the same results on a direct injection engine as the fuel is not going past the intake valves and instead directly in into the combustion chamber and most cars built today are direct injected.

When you buy gas at a non branded station, you may be getting any brand available as it frees up the owner to buy whatever is cheapest, sometimes this will be Top Tier, sometimes not. I work in the industry and station owners will look at fuel prices all through the day to decide on what to buy.

As they said, nothing says a non Top Tier fuel won't have as high of additives as a Top Tier, just no guarantee they will. They also didn't pay for the certification.

Does anyone know if Sam's club gas is Top Tier?

Doesn't look like it. But glad to find Costco on the list!

A new article came out, so we had to make a new thread.

As someone who only gets name brand gas (Shell, Chevron, Exxon) I'm not too worried.

[jkoral]

BMW service bulletin 13 02 06 is about top tier gas. This one is from 2006, I don't know if there is a newer one.

[Petrolhead3010]

Not sure how accurate this study is. I buy fuel from my local Fred Meyer grocery store. It doesn't state that it is TT but the fuel is from Shell, who is TT

Same here.

How do you know the fuel is from Shell?

Most non branded fuels prefer to be non branded because it gives them the ability to buy it from the cheapest source. I am in the industry and fuel retailers will watch the prices all day in the hopes of saving a few cents per gallon on the next load.

If Fred Meyer really is always Shell gas I am surprised they don't take advantage of this strong brand to sell more fuel.

It was something I could've sworn I had read about. But I can no longer find it. So I am incorrect. Both companies share rewards points, but that is all. Guess I'll be going back to Shell from now on. All for the better, since they're the only ones locally who have E85

People look at me funny when pulling up with an M6 GC at Costco gas. But if you look up Costco gas, they are actually very good quality.

I am guessing they have decided it is worth the "Top Tier" to purchase from one of the Top Tier brands, then still work the system to get the least expensive Top Tier they can find (and I see nothing wrong with this). I also buy from them when it is convenient.

It's not, it's a big truck that says "CROWLEY", which is the same truck that fills up the Shell station, or maybe it is, who cares. I don't worry about it. I won't fill up at some shady probably-don't-have-working-filters gas station, but otherwise, it's way way overblown. In a court of law, it's probably not reasonable that you have to fill up at only two brands of gas stations, as long as you are using the right octane, but hell, we can't get above 90 in Alaska, however, there's a BMW dealership and they sell cars here, so it must be ok. If not, that's what lawyers are for.

My belief is that "top tier" or octane rating don't matter in our cars as much as the poor quality, inefficient, additives (Ethanol, MTBE, etc.) that all the corrupt politicians have legislated into our fuel. 100% pure gasoline is higher in energy and more efficient than Gasohol (10% Ethanol) and E85 (85% Ethanol), resulting in increased engine power and MPG. Try searching http://pure-gas.org for a gas station that sells Ethanol-free gas near you. That said, unleaded Ethanol-free gas is difficult to find where I live.
