Hey, my 2007 V10 is the same way! It came with 3.73 gears and got 12 mpg. I changed gearing to 4.56 and still get 12 mpg - uphill, downhill, freeway at 75 mph or dirt road at 45 mph. I'm thinking it's a plot that Ford and the oil companies are collaborating on!That sounds like a 460 don't matter what your doing it's mileage is it's mileage.
Where wee you driving where you ran into 14-26% grades?2010 2.5L CVT Subaru OB our trip this week was with the 4x6 lifetime tent trailer + two parents bikes on the roof in fork mounts with 30inch wide 7ft long roof box between the bikes on 54inch bars + two kids our trip average was 19.5mpg. Similar trips without the bikes on the lid we saw 21-22mpg. No roof rack gear or trailer we typically see trip averages of 28-32mpg. Around town we get 23-24mpg.
2007 Toyota Sequoia Limited 4.7L (stock sized BFG Rugged Terrains) our trip this summer over a 9000ft pass with 14-26% grades pulling the LifeTime Tent Trailer 5 passengers and gear we were averaging 14mpg for the trip. No trailer road trips we typically get 17mpg.
Just for the hell of it Grandpas 2005 SLK350 which the wife and I are taking next week on a two day trip we typically see 28-30mpg averages as long as we keep it under 85mph.
The old 93 Land Cruiser we never got better than 13mpg and the worst was 10mpg didn't matter what we were hauling or towing that was what we got with 285 BFG's on it.
