Depends on where you geyt it from. You buy Shell. youre buying the best your car is going to get. Period

Oh well, can't argue with idiots...they just bring you to their level.

There is no need for name calling!

Sounds like EFI's got a stick up his ass. lol

Currently I only use Shell 93, this would be Citgo 91.

True, I forget about those 91 grade states. Shell 93 is the best down here so i should rephrase my statement to the best down in LA. is Shell 93 for your camaro SS.

Ok, nevermind. This is useless.

Nope my V6. I know there are many that would say it's not needed but I have ran both and certainly felt a difference. For me the couple of hundred dollars extra it costs me a year is worth it.

e10 won't affect power in any noticable way that you'll be able to see. It will have the effect of slightly increasing fuel used which has the benefit of a cooler intake air charge but less miles per gallon but at a 10% ratio it won't be anything noticable. Benefits of ethanol start to really show at the 42%+ level.

Thanks for the explanation.

Guess I'll stick with Shell since I'm not a Citgo supporter to begin with.

A lot of misinformation here. Here are the facts:

Ethanol burns colder and thus produces less energy per volume than its non-ethanol counterpart. This results in reduced MPG when ethanol is used
There is no by-product in ethanol gas that adds any more contaminants from combustion than non-ethanol gas. No "gunk" at all
Ethanol does not have detrimental issues with plastics and rubber seals, etc. Methanol, however, is corrosive to these materials
Modern vehicles from mid-90's and up are designed to work best using 10% ethanol-blended fuel. They are calibrated to get the best balance of power and economy using ethanol fuel
In many areas, the only way you can get 93 octane fuel is to use ethanol. The "regular" version of the same brand of fuel is typically 91 octane, or 89 octane

Hope this helps you.

Great info!

Edit: I would like to add to your list, and this applies to e10, e85, and e100 mixes that just because ethanol contains less energy per unit it simply means you have to burn more fuel per unit of air, not that the engine makes less power on ethanol blended fuel. There are benefits and consequences to this, mainly cooler intake air charge resulting in more power due to detonation resistance and less mpg because of the additional fuel used, which you covered.

For your car, the only benefit is fuel economy. In small engines (i.e. lawn tractors, trimmers, chain saws and blowers), the benefit is longevity of the equipment. Automotive manufacturers take great care ensuring that the polymers used in their products will be resistant to ethanol. Manufacturers of small engine products typically do not do so much. Therefore, corrosion in this type of application would be more significant. In addition, ethanol is hygroscopic meaning that it absorbs water. Over time, usually in a month or so, the ethanol/water phase separates to the bottom of your tank (ethanol and water are more dense than gasoline). This isn't such a big problem with your car because you usually won't keep the same gas for months at a time.
