Chevron's refinery is in Richmond, CA (15 minutes from my work). They do have a gas station right there too.....hm......maybe I should get the fill-ups there instead of SF....

BTW, Shell's refinery is in Rodeo, CA......very close by too!

[QUOTE=duckduck;2601915]Is there a reason why you want to use Ethanol? (My guess is to become less dependent on foreign oil)

lol, I don't even know if Ethanol is good for your engine or not.

But as a Top Tier gasoline company, I'm guessing(or hoping) that it's at least not harmful.

I'll let you know if my IS breaks down relatively early .

[QUOTE=joonsta;2602036]correct me if i am wrong, I think that has something to do with the emission (esp in CA)......

duckduck

[QUOTE=kickin8;2602043]hmm..Ethanol doesn't necessarily burn cleaner than gasoline. However, ethanol can be made from the corn produced in the United States, thereby relying less on foreign oil.

For those that didn't know though, ethanol provides less energy than gasoline.

aren't stations attached to the refinery more expensive? i know the mobil station at the refinery in torrance is the most expensive station around.

Ethanol is being substituted for MTBE (methyl tertiary-butyl ether) in gasoline as an "oxygenate" to raise the oxygen content of the fuel, cutting emissions of O3 - a particular problem in urban areas. MTBE was found to be a particularly nasty product when it leaches into groundwater, the common source being leaking fuel storage tanks. Some states (including California) have made banned MTBE, making ethanol mandatory.

While it will not harm a modern engine (in concentrations of 10% or so), it does not provide as much energy as gasoline, thus can be expected to produce observably lower mileage.

A couple of months ago I performed a rough test to the two fuels in my RX 330: RESULTS HERE. I wouldn't have believed the difference, but as unscientific as it may be, I think it points to some demonstrated truth - ethanol is not an efficient motor fuel.

You would think delivery costs would be less, but in practice, the market is going to determine selling price. Over in Deer Park, TX, the site of the nation's largest Shell refinery, there is a Texaco station about a block from Shell's main gate that is ALWAYS at least three cents cheaper per gallon. (Other Texaco stations are not as cheap.) I think they just like sticking it in the eye of the Shell employees who have their "own" gas station at the main gate - that is always more expensive. . .

I use Shell and Chevron. Shell has the best commercial

I alternate between shell and chevron. Not because of any gimmicks but because I believe they have the best detergents. Techron might be the single best detergent out there, their gas cleaners have visibly improved fuel flows (literally one guy had his engine open and saw the transition in fluid flow)

All gas stations use pretty much the same base gasoline stock. The only other difference besides the detergent is the age of the gas. Usually those cheap "freestate" stations where you pay cash, get the older gas and some dubious detergent.

I like to alternate gas, because the detergents clean up after one another.

Shell. I used 76 once and my car felt a little rough. Maybe its just my head though.

Chevron 93 Octane

Mobil, Amoco, and Chevron used to be the best and highest-quality brands....but Mobil and Amoco were sold off to Exxon and BP, so you really don't know what you are getting any more with those two.

Among today's brands, you guys are correct.......there is little question that Shell and Chevron have the best detergent packages, and are generally considered the highest quality short of pure racing gasoline. Under normal circumstances, those are the only two brands I will put in my own car.

In Mexico, only type of gas is the national Pemex, so I use their Premium 92 octane. However, my favorites in the U.S. are Chevron for daily use and Sunoco for track use.
