No the Titan call for 87 octane only. Only if you're tuned for it or have the VK Pro is it required.

He is correct! Early Titans stated that "premium fuel recommended". Mine did and I posted the page in the owners manual at the time.

Paulsen, just use 87 octane. That's what I use and she runs perfectly.

Per the manual I use 85, being high altitude in Denver.
Is that right? Interesting. I'd have thought premium would be needed at high altitude...lol...shows how much I pay attention since I'm closer to sea level. I know turbos lose oomph at high altitudes...moreso than a supercharger does. Cool...didn't know that.

If you have in your possession on of them early release propaganda page, it does state that the Titan/Armad/QX56 required 91 octane. Well from a marketing stand point it's hard to sell a half ton work truck requiring premium fuel. So they changed the Titan/Armada to 87 and keep the QX at 91. heck if you can afford a luxury SUV you don't care about gas price.:D

Since it lacks Oxygen, allowing the lower octane, allows an easier burn to compensate. :)
