Before anyone gets excited about the latest test showing that the 3.5 Ecoboost runs a lot better on 93 octane please take notice that this is the HO version only available in the Raptor and the Limite...

When you are sitting on the couch watching tv it doesn’t matter if you are at sea level 20.9% oxygen or at 9000 ft and only 16% O2. You aren’t doing much work so it won’t matter.
Your vehicle will run on 87 octane under minimal load just fine.
Now try and play tennis, basketball, push start a motorcycle etc with low O2 and this is how your vehicle will feel with 87 octane when under a load, the lower the altitude the worse.
It will re tard (wow got censored for re-tard) the timing and you make less torque/power/fuel mileage.
This is an RV forum and most are towing or pushing motor homes so the vehicle is working hard, I would use premium unleaded On a turbo vehicle for sure.
