I put 87 octane in my 2019 Premier, and I can get 30-32 on the highway. I had a 1990 Pontiac Bonneville with the 3.8L V-6. I used to put 89 octane in, despite the manual calling for 87. Darn if the car started backfiring after a year or so. The mechanic said to only put in 87. So, I have always gone by the manual since then. I had a 2010 Malibu with the same 3.6L V-6, and my wife's 2014 GMC Terrain had the 3.6L. They did just fine with 87 octane.
I've got a loaded Burgundy 2015 LTZ. All options except the Radar-Cruise & phone charging mat. I've got the 20" rims like yours too. I get 25-28 mpg at Interstate speeds. My engine only sees Top-Tier Premium from Shell-Stations or Holiday. Seafoam use once a month, when tank is 1/4 full, I pour in 1/3 bottle. The Blue lighting trimming the interior doors was always there. My '15 has it on all doors. I know all LTZ's/Premiers during the 2014-2020 Model-run came with it.
I've got a 2019 Premier and get 28mpg on the Interstate at a little above sea level on regular gas. Can't complain. 17-18 around town with spirited driving.
Hey CJ, no warning lights needed. Just pay attention to the gas guage. At a quarter of a tank, filler up. Easy! I have a 2014 Impala and I have never seen the warning that I was almost out of gas.

Nice Love my Premier too. In 2014 the nighttime glow went to the back doors too. They took it away in 2015-2020. I wished they hadn’t done that.
I have a 2016 and the glow is in the back too
@@DavidAlejandro201990yep sadly its 2017-2020... i have a 17 premier 99.9% fully loaded but no glow in the back

Ethanol is equivalent to 100 octane.
