Many people say that one type of gas is better than the other...
I've been told the high-end nationwide gas stations like Shell and Mobile have a fuel injection cleaning additives which given a choice should be used obviously in premium octane
Is this all bull and all premium gas is the same or should we be careful and use one over the other?
Your thoughts...

It is not all the same. Stay with the name brands for your Z06. It's the additives that make the difference.

I like Sunoco Ultra 94
Amoco Platinum or Gold 93 as an alternative.

And for track events I use Sunoco GT 100.

Not only are we taxed to death here in Ca., we also have this low octane stuff they pedal off as premium with a rating of 91. Simply pathetic!

I have always used only one brand, Union 76. They are the only "major" in the state that no longer uses the MTBE. By burning 76, I am not contributing to putting anymore poison into the water tables!

Between the bureaucratic bullshit of smog checks, putting bullshit in the gas, 91 octane premium, it's amazing anyone still lives in this state!!

I totally agree DJ, Sunoco Ultra 94 is the best. I'll add that Mobil or Citgo 93 is also a good alternative. I had some very bad experiences with Shell 93 from different Shell stations.

Here in Colorado Springs 91 is the only choice. So I add a little octane booster such as "Outlaw".

JACK FRISSINA · 07-04-2003, 02:36 PM

All Gas is the same, the differences is the additives. Gas is refinded the piped all over the country, in the same pipeline. So Amoco puts 1000 gallons in the pipe in Houston for NY, it does not have to wait of that same 1000 gallons to arrive a few days later. It takes the immediate delivery of 1000 gal in NY. At this point Amoco has a distribution center where it adds it additives and fills the tankers to deliver to the stations. So the refined gas is the same according to Octane, then additives make the difference.

The above responses are correct. If you would like more in depth reasons behind them, search this forum for "refinery". I wrote a fairly exhaustive post on how we get gas from the refineries....

For everyone's information, the Corvette Assembly Plant factory fill is BP.

timz06 · 07-04-2003, 08:15 PM

Everybody says name brands, but where is the evidence that it is better? I think a lot of people have been duped by marketing.

Unless the dealer is committing fraud all 92 octane gas should be 92 octane. I will tell you a secret (maybe it isn't a secret). I grew up in Lima, Ohio. My father worked for Standard Oil of Ohio (Sohio, later BP). There was a Sohio oil refinery in Lima. When local gas stations (Shell, Mobil, Marathon, etc.) needed gasoline quickly, they called the Sohio plant who would use their unmarked tankers to make deliveries.

I know some of you guys can remember the old days when most ads on TV were for cigarettes and gasoline. All of the major oil companies used to extol the virtues of the additives in their gas. Then the arab oil embargo and gas prices shot way up and all people cared about was cheap. That is when gasoline companies quit advertising and sold gas as a commodity.

Even though some of you guys think that some gas is better than other gas, oil companies see themselves in a commodity business today, not a differentiated product business.

Yeah, here in CA all we can get is "91" pump octane MAX, no matter which brand we buy. I don't have any proof but that makes me think California Z06 owners are down a little bit in power. I don't hear any knock (pings) from my engine, even on a hot day, but I suspect there may still be trace (unaudible)detonation in the engine.

Now here's the rub, Californians get the worst gas in the nation but have to pay MORE to get it. Premium (91) unleaded right now, from any of the big named brand gas stations, is selling for close to $2.10 per gallon. At the outset of the War in Iraq, gas was over $2.30 per gallon, so I guess we shouldn't complain.
