here's some light reading showing that some DO work, unfortunately only measuring RON instead of AKI, but the picture is pretty clear. at the price, you might as well just run race gas.

the handy graph from the above link for those who don't want to read:


For AKI, these 2.5-2.8 RON increases will translate into something like 1-2 AKI, bringing your 91 pump gas to just above 92. You won't notice it, and neither will your car.

Asked my friend from Carolina, he didn't steam and used ordinary gas. Of course I understand that this is not the best idea, but if you do not care about the rated power of your car, then you will at least save time to avoid problems with the fuel system. But as I understand it with a motor trader I would advise just wait and looking at the car in the garage). Or come to us in Florida and fill up with the right octane fuel.

damn near 100% of tuners around here openly state not to run nonoxy, so on that alone I'd take the 93.

from an octane perspective, 91 is 91 and 93 is 93. e0 to e10 is more or less meaningless between the two.

The engines in 991.2 Porsches are designed to work "...with fuel containing up to 15% ethanol.". Putting in non-ethanol fuel won't help (or hurt) the engine. And, it costs more!

I had to put 3 gallons of 87 in my .1 turbo today to get home. Stupid North Carolina freak out has no 93 anywhere. It’s hard not to flog this damn car! All patience was on hand getting home today.
