I usually use mobil, i think it contains ethenol but seems like it lasts longer compared to shell.

 

No I saw that. My points agree with that. Additive packages are added after a company takes it from the pipeline. All companies get their fuel from the same source, and the difference is additive packages added after that.

The last line in your quote about detergents (aka additives) has a keyword in that line..."often". For most companies, thats the case, but there are a few companies where its not just a quart of detergents.

Its very similar to oils. Most companies get their basestocks from the same place, but the differences are usually their additive packages.

 

The best gas is any top brand without the ethanol in it. That stuff is bad for your car and deadly for 2 cycle engines like weedeaters. I lost a blower one time and learned the hard way what that crap will do. It eats away at the fuel lines and inner carb components of the small engines so imagine what it is doing to our G's. Can't be good. The shelf life is only 2 to 3 months as well.

Whoever got this stuff started should be banned to driving Yugo's for the rest of their time!

 

I can't find any gas station around me in Atlanta that sells without 10% ethanol. Any specific brand gas that i should check out?

 

There are some metro areas that won't sell anything without the ethanol. I used to live in Dallas and you could not find it anywhere without it. I would just try to use major companies like Shell or Exxon/Mobil. The ethanol probably isn't real bad for your car but it is not the best that is for sure. It causes mileage to be worse among other things and it goes stale fast.

I used to have a 67 Chevelle and I did not drive it all that much so I kept a quarter tank in it and used fuel stabilizer to counter act the stuff. It seemed to work OK and I never had carb problems but it was a hassle.

 

Usually use Mobil, but switched to shell today and noticed a nice increase in mpg... Shell it is then!

 

I'll bet money the owner's manual for that blower explicitly forbade use of gasoline with ethanol.

Alcohols can eat rubber but automakers have been using o-rings and gaskets that are impervious to alcohol for a couple of decades now. Shelf life is a different issue and you're right, it's not very long.

 

I have been keeping accurate records based on my fuel usage since first buying the car. My results are as follows:

Shell - Good performance, high price, decent mpg
Sunoco - Best performance, average price, lower mpg
Giant - horrific performance, low price, better mpg
Exxon - decent performance, average price, best mpg

I have been running Sunoco Ultra 93 the past 8 tanks and can say the performance has never been better, although my MPG is only 16-17 currently. I rarely drive highway so cant give you any numbers there. It all really depends on what you want, how you drive, and what matters most.

 

Anyone who uses Shell and Chevron know which has better mpg or are they pretty much the same?

 

You can't compare brands like that without specifying your location. Reformulated gasoline is different enough from gas sold in non-pollution areas that comparison isn't valid enough to create Neddy's matrix. Reformulated gas has lower RVP and generally has ethanol.

Besides, not all brands are nation-wide. No Sunoco stations in Houston, for example.

 

ha, Neddy's matrix. Morpheus and I worked on our fuel charts together.

I am in VA and our gas is reformulated with 10% ethanol.

 

My apologies to Morpheus.

 

I usually go for 76, Chevron or Shell in no particular order.

 

i dont give a ****, it is $1.20/gal here :P

 

LOL....

I usually buy whatever is cheapest for 87. But I use shell for 93 because I can use my points for discounts.
