Actually, they are lab apparatus 'engines' that they use to test....and of course, as you know, the tests are not done on every batch of gas....saying you never get top tier gas at a top tier station cannot be substantiated....it's a marketing gimmic for the most part, one that really never took off......

There was a Ragin Cajun on Pass Time on Speed Channel last night. Was that you? He had a bad *** drag car.

The engines used are real car engines, not some sort of unrealistic lab engine. My memory says they settled on a Ford 4 cylinder engine, but that could be wrong. You’d have to look it up under the relevant ASTM test procedure. It’s true that the engine is run while connected to a dynamometer, not while installed in a car and driven on the street. But that is necessary so that you get the exact same conditions every time. It is a very real and genuine engine test, not some sort of silly lab apparatus like the Royal Purple oil test that has nothing whatever to do with reality. You are correct in saying the tests are not done on every batch of gas. However, you do get the additive package used for the test in every batch of gas. Your third comment as worded doesn’t make sense. I assume it was supposed to say that I can’t substantiate the fact that you always get top tier additives at a top tier station. In a very limited way, that’s true. One can never guarantee against an unscrupulous operator claiming one thing and selling another. But penalties for doing that are high, so you can be confident it’s not a frequent practice. And as for the marketing gimmick, whose gimmick would it be? Certainly not the oil companies. They didn’t start it, the car companies started it to reduce their warranty costs. The oil companies who comply with the specs decided that they wanted to be on the list of top tier companies so that customers who followed the car company’s recommendation would be able to consider their fuel. The oil companies don’t advertise top tier very much because they’d rather advertise their own additives like Techron or Nitrogen Enriched, that only their company offers. If they heavily advertised top tier, that would force them to admit that top tier additives like Techron and Nitrogen Enriched give pretty much equivalent performance. Bottom line, top tier carries a real and demonstrable benefit in cleanliness. Like anything else, you can choose not to believe it. You can also choose to believe the benefit is so small that it’s not worth paying extra for. Indeed, the benefit is not huge. But it’s big enough that the car companies thought it was worthwhile to pursue.

Ultra 94 has ethanol in the GTA

*Ragin Cajun*

Nope wasnt me.




The tankers do have multiple compartments. Its not possible to carry that much weight without supports in the container. If you look at the side of the tanker you will see multiple outlets. Each is used to tap a different tank in the container. So, its totally possible for one tanker to deliver many different types of fuel.

I actually live near a few refineries and have friends that work there. All gas is refined at the same place but the additives are incorporated based on the customers specs. Usually the additives are introduced while the tanker is being filled at a specific ratio based on the customer. So, cheaper gas does have less additives due to the specs and who is ordering it.

In checking my mileage, I have consistently found that gasoline with ethanol delivers fewer miles per gallon. Buying 100% gasoline pays for itself in better mileage.

Real gas is awesome! I average 5% better mpg....I don't think it pays for itself, but I enjoy giving the finger to the government.....

Leave it to Petro Canada to screw up 94..

Who has ethanol free in the GTA??..Ed

Mad*Max

Shell V-Power, that is all I use ever since I found out - these idiots have such a good product and don't even advertise the fact that it is ethanol free.

We have a tough time finding normal gas here in the states....

Mad*Max

In the US, if there is ethanol in the gas do they post it at the pumps like here? The reason I ask is because I found lots of Shells on a recent 5,000 mile trip through the mid-West and I don't remember seeing mention of ethanol at most pumps, however, some non-Shell pumps did mention at the pump.

They used to when they first started with the bs, not so much any more. Most stickers you see are original to the program and worn. It's a state by state thing and most states mandate it, no exceptions. Maryland has several loopholes in their law that allow limited sales of no ethanol, but it's only at small mom and pop type stations, all major brands have ethanol sadly....

Gitiup

I use only premium fuel in both my Vette's. C6's get good gas milage so why bother on the cheap stuff.

Keith Tedford

I guess I'm down to Shell premium if Ultra 94 has ethanol. Sad.

Also, I would stay away from Raceway, Pilot, Walmart gas, any of those cheap gas stations that aren't part of the major corp. I used the cheap stuff in a previous car and could tell that decline in performance.

Arco has the best prices. Costco is usually the same price as Arco so that tells you Arco has the lowest prices.

LS WON

I talked to the Costco driver who delivers the gas and the fuel comes from Tesoro refinery in this area. The driver told me he uses Chevron in his cars. Costco doesn't always get the same brand of gas. On my Corvette I have been consistent using 91 octane Chevron. I Used Arco 91 octane in Corvette once.
In my other car I always use Arco. Chevron gas is the most expensive around here and Arco and Costco is the lowest cost.

LS WON

Any brand of gas is good gas as long as it is 91 Octane?

rcallen484

I always use 91 octane (highest we have in AZ that I know of) and the places I buy it are VERY heavy volume discount joints like QT or AM/PM or Fry's (10 cent per gallon discount with $100 groceries in a month). I have had my 2011 11 months and it has 14,500 miles on it. Easy to put miles on a vehicle in AZ.

Is 'cheap' gas somehow made differently than expensive gas?
