No worries, mate... all in good fun!
I can tell you that i have put premium in my Tiguan a few times due to these low gas prices latley. No difference in fuel mileage or hp improvement on my arse dyno that i can feel, anyway.
Maybe try that yourself, maybe your car will respond well.
Hey oily,
I have, with equal results. I would think a 20hp increase would be noticeable. Fuel mileage was the same as well. We're on the same page it appears. Maybe it will be different now that it's broken 12k miles.
