I searched around and couldn't really find any posts about this so I thought I'd ask the question. What are you running for fuel, regular or premium?
Yupp, 2.0 requires 91 minimum.I had the 3.8, now 3.6 and have used regular in both. Figured i wouldnt see enough performance or fuel mileage gain to justify the near 20 percent hike in cost around here, but wouldnt be surprised if that new 2.0L required premium.
Mine seems to hold 5th better on the freeway with 91. But it's probably just in my head.
The word is only if it is tuned for it. Higher octane fuels have a slower burn allowing for more timing. It is the addition of timing that gives us more power. Unless more timing can be added there is no improvement on power. I left out compression because it is fixed.It probably does feel like more pull. Higher octane brings higher Ftlbs torque, especially when tuned for it.
My old Dodge truck manual suggested running premium when towing..
