Gasoline Brands
Hey guys,
I recently noticed something and wanted your opinions:
Have you ever noticed that you get varying performance from different brands of gasoline? It can even be the same brand of gas from different stations. Sometimes I particularly noticed a different in the liveliness of the car after filling up at some stations and at other stations...the car feels fantastic.
Whats the deal?

different amounts of ethanol? I know in states where it gets cold, stations increase the ethanol in the gasoline to reduce emissions, but this hurts performance somewhat. Ur in Texas tho, so I really don't know. Best guess is a variance of gasoline purity?

I have actually found that Chevron seems to give the best performance. I filled up with Shell gas a couple weeks ago and the car felt really sluggish.

IMO gas is gas, coming from the major stations of course, excluding mom n' pop stores that have been know to have water in their fuel. The only real difference is the octane. Brand wise, I say they're all the same....

all gas stations pump from the same pipeline,at distribution centers each brand is modified with their own detergents and additives to seperate themselves.....sunoco has a higher standard and usually tests higher than the posted octane rating.10% water is the max allowable water in gas,most cheapo stations take this right to the limit.thats why you get worse mileage with cheap fuel.sunoco sets their own water standard to 1%.so if you do the math you are actually getting more gas for the money.if you buy 10 gallons of cheapo,10% of that is one gallon of mixed water....which is pretty expensive water.stations are randomly tested by the government and all have a different method of compliance,i like sunoco's

I've been keeping track of my gas mileage -- by brand -- and Shell gives me my best mileage, followed closely by Chevron.
Arco is only cheaper if it's at least 11 cents per gallon less than Shell, and rarely is it *quite* that cheap (plus my Z runs like crap in comparison).
The only way to tell if gas is cheaper is to calculate gallons per 1000 miles. For example, our Armada only takes regular, but when towing running premium meant that we needed one less fuel fill-up in 1000 miles. Odd, but true.

When I was Turbo'd I would log UTEC Knocks also...heres what I found..
MOBIL, SUNOCO both SUCK !!!
EXXON was the only one that really worked for me..I know mobile and exxon are sort of the same company..but that was the only gas that didnt make my car knock or at least send a knock signal...

That is a good place to start. And yes, thare ARE differences among gasolines, with different results when it comes to performanace and efficiency. What most people post in threads like this is biased, subjective info, with little factual basis. Search this and other auto forums, and you will find enough info to keep you busy for hours.

You are entitled to you opinion, as uneducated as it may be. I would rather people find their own answers than listen to someone who couldn't compose a single, grammatically correct sentence, if their life depended on it.
