Hey there,
Has anyone tested the 0-60 times of the '16/'17 on Unleaded vs. Premium gas?

I have, and can tell you that 91 octane makes a huge difference in drivability over 87.
My observations when using 91:
The engine is smoother
there is less turbo lag
the throttle response is faster
the turbo spools up faster and consistently
there torque down low is stronger
the engine hp is more in the high rpms (over 4000rpms)
What I find disappointing when using 87, is the turbo pressure was very inconsistent. There were times where I would accelerate and there was a depressing lack of torque. I also noticed engine ping a few times while using 87.
I now only use 91 exclusively
Different measurement system. Octane is measured using either a Research Octane Number (RON) or Motor Octane Number (MON). The tests are different, and the MON comes in about 8 to 12 points lower than the RON for the same gasoline.Wow, our standard petrol in Aus is 91, with 95 and 98 ron being our Premium...
