That's all I plan to use. I've only had mine for 3 tank fills, but so far 87 is fine. I had 2 Buick Regals prior (2015, 2017) both with 2.0 turbos (259hp, 295lb torque) and they also ran fine with 87.
I believe the manufacturers specify the higher octane in order to reach their stated, peak HP...
Received an email Saturday, stating that it was Built. Today, 2/6/23 received another stating that it's been shipped, With an estimated arrival to Dealership between April 9th and 15th. Im hoping it's actually going to be sooner.
I'm in MD.
