91 all day...last weekend I drove from Telluride to Seattle, 1226 miles, nonstop....20 hrs. We put 2966 miles on the car in 8 days. 91 octane the whole trip..2008 turbo...stock...
Holy schmokes, every time octane pops up I'm amazed. 95 is the minimum anywhere here in the Netherlands with a 102 being available straight from the pump at a max distance of about 50KM from where ever you are.
Awesome. How great are these cars for multi day road touring?!
Actually not bad. Road noise is pretty high especially on less than smooth highways, I think a DSC box may help that some. Plenty of luggage space for 2. SiriusXM was nice. We got 24mpg over 3000 miles, and 91 octane was around $3.29 or less in Utah, Idaho, and Colorado. We went from sea level to over 11,000'...
They chew up miles in the most amazing way. It's almost like they were built for it! We're headed to Moab and Arches National Park in the fall...

Nice. I've driven mine about 60,000kms over the last 6 years, and most of that has been weekend blasts and multi day road touring, with a decent number of track days in between. I've found it a perfect balance between comfort and focus, and can't see myself replacing the car any time soon. Good to see others out enjoying there's as they should be.
Good conversation here - when datalogging, you're looking for knock retard.
In Durametric, it's one of the "Z" items, listed as 'Retardation_cylinder_x' for 1-6, and will log as 0 with no retard (meaning the engine is not detecting knock at your commanded timing and current boost level). There will be small negative values as the ECU pulls some timing out to manage knock (it's a measure of commanded timing vs. actual timing).
In hot weather on crappy gas, it's common for stock cars to still have some knock retard, and tuned cars (more boost) to have quite a bit. Opinions on how 'safe' it is are all over the board, but no one will say it's 'ideal'.
Run the best fuel you can. For those with access, a few gallons of 100 or 110 unleaded should take care of any knock. A couple gallons of E85 to a full tank of 91 can do the same. A little methanol injection is a common safety net as well.

Car will run fine especially just cruising. Mine seems to run perfect on 91 non-ethanol gas but when I pull data logs I can see the knock retard to the timing. This means some HP left on the table and possibly a little fuel economy if it enriches the mixture to protect.
