Note however that if I wind up with an GMT926 / 936 Escalade, eventually, the 6.2L will be replaced by a 6.0L.
What’s the benefit of the 6.0L over the 6.2L?
Most used 6.0L are FAR cheaper than most used 6.2L.
Most used 6.0L are also less abused / less mistreated / less under-maintained, compared to most used 6.2L.
Just because you COULD operate a 6.2L on 87 octane, doesn't mean you SHOULD ...
Most cheap@$$ idiotards 'forget' to drive the 6.2L on 87 octane GENTLY, instead they drive them hard, pointlessly, wearing them out if not breaking them for fun.
By the way, how much power & torque is a 6.2L rated @, on 87 octane?
(How much WOULD a 6.2L be rated, if the spark tables were intently written for 87 / 89 octane?)
Compare the LY6 / L96 / LC8 6.0L V8s with 9.6:1 scr on 87 octane, vs a 6.2L with 10.5:1 scr on 91 octane (L99 with 10.4:1 scr on 91 octane, same power & torque)
LY6 / L96 / LC8 ≈ 360 horses & 380 torques ... 6.2L ≈ 400 horses & 410 torques
So far as bang for the buck goes, I think LY6 / L96 / LC8 compete respectably vs L92 / L9H / L94 / L99.
