While I respect the opinions and the points of view. I too have over the last 30 years of driving, had a Chrysler Laser 2.2 Turbo, Cadillac STS, Cadillac Deville, both with NorthStar engines, Pontiac Grandprix with 3.8SC, Two Chevy Trax, 13,15 and now the Terrain 2.0. Not one issue with using 87 octane with only the Grandprix really needing 91 for it to produce a little more power. Granted there are vehicles that must have high octane, any Cadillac 4.9 engine, and the 4.5 as they do not have the knock sensors to retard when required.

It also looks like GMC is bringing back the 'Jimmy' for the 2021/2022 MY. It appears that it will be based on the Traverse and Enclave bodies which would make sense as GMC does not have a vehicle in that size anymore, notwithstanding the downsized Acadia. Google it and see.
