One, I can't rave enough on the improvement with my fuel mileage using Shell premium with Nitro. EPA rated at 24 mpg the old Volvo with 120K on the clock gave me 29.7 mpg with maximum speed set at 65 miles per hour. Guys that was what I was getting with E0 ten years ago. A funny one for the members who can relate, I'm sitting at a traffic light on Airport Pulling road in Naples just off the right quarter panel of a lifted (12-18 inches) Ford Expedition with some large oversize tires and a specialty dropped trailer hitch. I noticed the license plate and a very big smile came across my face. The truck was from Oregon. I wish it hadn't been so dark out or I would have snapped a picture or two for you guys. Can you imagine what it cost the owner to drive that lifted beast across the country, 3,215 miles if we use Portland as a starting point ? Lastly, as I was cruising the interstate something really popped out at me. The large semi's with aero packages, roof air deflectors, full body side flaring, extended panels on the cab covering the space between it and the trailer, as well as air deflectors hanging under the trailer, were all running under 65 mph, in the 60-62 mph range. I should know I passed every one of them with my cruise set at 65 mph. On the other hand the trucks with trailers that only had roof air deflectors with no other aero treatments were all running 65 plus up to and over the 70 mph speed limit. I think more than a few of these drivers have figured out how to save a lot of money on gas?
