Hybrids... the crook catching machine

Re: Hybrids... the crook catching machine
Close, but unrelated. I don't think Tier 2 is related to Top Tier in any way except pehaps some level of co-marketing hype.
The Top Tier program was, as prevously stated, set up by a group of automakers with the objective of making a cleaner fuel from the perspective of engine life and engine performance.
Tier 2, from everything I have read, was completely different and setup by EPA to reduce polluting emmision from fuel, most specifically sulfur related emissions.
The two are not mutually exclusive -- or inclusive.

I still am wondering where you get this notion of "Tier 1" gasoline from. Are you talking about http://www.toptiergas.com/?

Re: Hybrids... the crook catching machine
www.toptiergas.com is what we are all talking about. The official name is Top Tier. However that site itself refers to the EPA standard gas as Type 2, implying that Top Tier is Type 1. I have no problem with calling it Top Tier or Type 1.
My difficulty in figuring out what Marianne is experiencing, is that, where I live, there are no big differences in price or performance between name brand gas of Top Tier or Tier 2 with the slight exception of Shell.
In NJ, Gas stations tend to be clumped together in groups with practically identical prices or single remote stations with high prices no matter what kind of gas it is. The gas in my town, a no-name brand and a Gulf station are always 10 to 12 cents more expensive then the stations on the big highway. On my way to and from my recreational basketball game last night I passed three EXXON stations, one wanted 3.07 for regular, one wanted 3.03 and one wanted 2.99. The Shell station near my town is about 5 cents higher then the no-name station, but the Shell station on the big highway is 5 cents lower. Stations are independently owned and often have prices that reflect their immediate competition, not a set price. The final result is that Top Tier and tier 2 are about the same price if you average it out. Unfortunately those stations are not conveniently on my way to work.
Performance wise we have never had a tank average better then 38.5 (long drive at the hight of summer) and never lower then 31.8( a blizzard week in the hight of winter) no matter what gas we use. (We normally use BP). Shell gives us a 1 to 2 MPG boost over EXXON and BP. All other gas is about the same. (average of 35 MPG)
If Marianne is averaging 35 MPG at one station, but only 28 at another then I agree something fishy is going on at that 28 station, but it is not that Top Tier gives a 7 MPG improvement over Tier 2. I just don't see it.

I'm a science dud so I can't answer this.
