Unless something changed in the manual, the 2.0T never mandated 91+. It recommended it for best performance. The ecu will adjust the timing if needed.

1. Ethanol does not contain as much energy per volume as gasAs I stated in an earlier post I run premium but I see some running ethanol free gas so is there a benefit ?
The only issue it will cause is lack of power and reduced efficiency and possibly some over heating.Just curious is everyone following the manual and use the premium gas ?
If you use regular will it really cause issues ?
I need to find a station close to me that has it so I can try a few tanks to see if I notice a difference1. Ethanol does not contain as much energy per volume as gas
2. Ethanol is corrosive/harder on fuel system components
3. Ethanol separates out over time and gunks up stuff
Ethanol is also hygroscopic, and contains some measure of water by the time it runs through the refining and distribution process and ends up in your tank. Not only does water not have any energy in it, it absorbs energy when it's converted to vapor in the combustion chamber, thus reducing engine output.1.

Seems in most fuels the MPG difference equates the price difference. Except when it comes to ethanol free. That stuff is expensive around here.Ethanol is also hygroscopic, and contains some measure of water by the time it runs through the refining and distribution process and ends up in your tank.

That said, I see no mileage or performance difference between alcohol infused regular and alcohol infused premium. (3.6 no etorque) But the difference when using alcohol-free premium is quite noticeable. It's the difference between 21 mpg and 24 mpg on the open road, as well as better throttle response from a stop.
