Jeep revs much freer, although no marked improvement in gas mileage.
I admit I also noticed my engines rev more free when going slightly lighter. I spend enough time behind the wheel that I am intimately aware of every sound,bounce and squeak my vehicles and engines make,so I notice every little thing,and since I practice launching I am very aware of my engines capabilities.
Thin is definitely in,and I'm slowly coming around.
