Just finished a 1550 mile trip in the 2007 Fronty (extended cab, 4 WD).  I left central PA last week with my wife and about 350 pounds of stuff in the truck.  We went to Washington DC where we put about 80 miles on driving in the DC suburban traffic.  Then on to Wilson NC.  From there, over to western NC near Asheville.  On that entire trip, I ran high test (Shell V power) and averaged 23.0 mpg at a speed of about 63 mph on the interststes. That included the DC suburban driving.  Today, I ran the whole way home at 70-72 mph and averaged just over 20 mpg.   Speed does hurt mileage.  But I was trying to get home before Hurricane Sandy hit and damaged anything.

I did air up the Cooper Discoverer CTS tires to 38 psi before leaving on the trip.  I was quite satisfied with the performance and mileage.  Truck now has about 48,000 miles on it.

Never used Startron but I have used Lucas fuel additive.  has no effect in the Frontier but adds about 2-3 mpg in my wife's Saturn.

I just set the cruise control and let it roll along.  I used to drive a lot faster than I do now but retirement has mellowed me and lightened my foot!  But I have no complaints about the way the truck handled or drove.  For a heavy "brick" moving through the air, it did a great job.
