What is the worst gas for performance, mileage, Cost?

BanningZ · 03-25-2009, 09:00 PM

I was intrigued by the previous thread of the best gas for performance, mileage, etc.

What are your experiences with poorly performing gas and who sold it to you?

I know I will never ever use Gas sold from an ARCO, Costco, Safeway, or Fred Meyer.

The last time I put ARCO gas in a car it knocked horribly. My fiancee's mom constantly puts ARCO or Safeway gas in her 2005 Camry LE and it always has a knock. Just for the sake of curiosity, we drove her car once and I filled it up with Chevron. Guess what? The knock disappeared...atleast for that tank.

USA Gasoline.

i've never even heard of those gases. you should start a poll of ppl's favorite gas

BanningZ · 03-25-2009, 09:09 PM

Go for it ssqpolo. I think that would be interesting.

As for me I've post whored enough for one day.

I've never had horrible experiences with any gas per se, but I do hear of ARCO having a bad rep.

I wouldn't recommend putting diesel or ethanol in your tank.

Seriously, as long as you put premium, it should be good to go. If you do come across crappy gas, fill it with the good stuff as quick as possible. I was kidding about the ethanol, but many gas co's are putting up to 10% Ethanol. I'd prefer not putting any in, but even co's like Chevron where I filled up yesterday puts up to 10% Ethanol in their mix.

Shell has been advertising a Nitrogen enriched formula..WTF? Nitrogen is the most abundent gas in the atmosphere..as in 78%. Who the hell are they trying to fool here? If it burns, it's already in a 78% environment. Last I checked Nitrogen isn't flamable, so enriching gas with Nitrogen seems like it would lower the combustibility and reduce power. Now if they said they have been adding NOS, well that's a different story, but I'm not sure how they can add a gas like NOS and keep it in solution. Not to mention it would also invalidate just about any warranty I could imagine.

^--- Why would they add a brand, to their gas?

(NOS is a brand, nitrous is what you mean :-p )

They're up to 20% ethanol around here now. Biggest problem with ethanol is that it absorbs water which can lead to corrosion or poor ignition. It takes a while so it really isn't a problem unless the car is sitting for months ... like many cars up in the North-East here do in the winter time.

An no, Nitrogen is not flammable. Nitrous oxide isn't flammable either for that matter, but it does contain a lot of oxygen which will increase the burn efficiency of a fuel and because it leaves the bottle so cold will drop the temperature of the charge. I have no idea what the Shell nitrogen enriched fuel supposedly does. They might be using the nitrogen to help "clean up" as it will have a tendency to bond to other elements at high temperatures.

So if anyone knows which suppliers have the lowest ethanol content in the North-East please let us know.
