Do you have backup from Shell on this statement? In FL, the pump says all grades have up to 10% E.

How is E helping with ambient heat?

Yup just like the Harvard "study" (scam) about cholesterol big sugar paid for in 1960's/70's "finding" cholesterol was the heart killer when in actuality sugar is the culprit!!!

What parameter is the Z using to retard timing? Intake or coolant temp? If coolant temp. simply get a Infiniti 21200-4W000 stat. If intake temp. nothing you can do about that other than CAI.

I'm typically around 185-190* in south florida with the above stat and haven't seen 200 yet with an all OE cooling system and no engine bay ventilation.

It should knock on anything below 91 and is why lesser octane fuels aren't listed in the owners manual.
