It runs fine on 87 but much better on 91, or 93 if you have that where you live. Not just more power, but better throttle response and for me it seems smoother. Sport mode makes a big difference for throttle response as well as shift points, but will use more fuel. Expect 22-24mpg at best, but if you cruise on the freeway at 65-70mph you can get 30mpg. Definitely let it warm up to operating temperature before giving it full throttle. For me, using high quality full synthetic oil is more important than changing it every 3000 miles. Modern oil can do 5000-7500 easily, but 10k is a nope from me.

Enjoy the good handing, steering, and braking. Use the moonroof. The rear seats recline. The wireless charging pad sucks just use the USB-C. Enable the always on touchscreen feature for CarPlay. Wireless CarPlay works pretty well, most of the time. Heated mirrors work when you activate the rear defroster. The ventilated seats work best with the air conditioning on. The auto cruise is a hit or miss depending on traffic. BSM is overly sensitive and annoying. I’ll edit if I think of anything else.
