Benefit? E85 generally has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This allows it to be used in higher-compression engines, which will produce more power per unit of displacement than gasoline counterparts.
If you're in colder climates, you might need to run something closer to E70, because the higher ignition temperature of the ethanol will prevent your car from starting up in cold/freezing weather.

Do not run E85 in your Porsche without upgrading your fuel system, pumps, gaskets, and sometimes even injectors to deal with it. You need to be pushing a much greater volume of fuel with E85. The stuff wreaks havoc with a fuel system not designed to run it along with exciting new corrosion issues.
Money is better spent on a set of Pure Turbos from the M Engineering folks. Leave the “cheap” E85 power to the Subaru folks, etc

Question when filling up: I usually drive until it shows less than 20 miles or less left in my tank because I live in a densely populated area that has a large number of places to get gas. When I go to fill it up, it usually 'stops' filling after I've pumped somewhere between 14-14.5 gallons of gas. When I say stop filling, I mean the pump handle pops and I have to squeeze again to start the gas flowing again. When that first stop occurs, and I start it again, I usually can fill another .75-1 gallon before it pops again, and then I can usually fill a little more one more time, totaling close to 15,5 gallons pumped. I'm trying to figure out why the handle pops when I'm filling when the tank can clearly take 1-2 more gallons. I guess I'm also assuming that the distance remaining includes the reserve and that I'm down to about a gallon when it says 20 miles left. Naturally I don't want to overfill and have gas shooting back at me, but I'd like to get as close to a full tank as I possibly can. Next one I'll get the extended size tank...

In the owner's manual, it says under Filling Quantities: "17 gallons with a reserve of approximately 2.1 gallons (vehicles with PDK) or approximately 2.6 gallons (vehicles with manual transmission)".
Does this means that there is a separate reserve tank that comes into play when the main tank is nearly depleted? If not, what does reserve capacity mean and what practical use does it have? In other words, if the total tank capacity is 17 gallons, why does it matter that there is a reserve of 2.1 or 2.6 gallons? Is it only that the low fuel warning light comes on when the tank reaches these levels?
