Just how far did you run this test? I read your link, but did not see this.
 
Your graph indicates at 74mph you achieved 24.7mpg.
 
I'm sorry, but I just don't believe this is 'real world'.
 
Mine gets about 19/19.5 at speeds around this. The very best I think I've gotten on mine was about 21.5.
 
My original tires indicate a max pressure of 35psi. The door tag has Honda's recommendation of 32psi. This small of an increase in tire pressure and a bed cover, in my opinion, would not increase milage by some 15% over my max milage. My milage was from fillup to fillup, which is usually 15 gallons or more.
 
If what you are reporting is a steady state mileage over a level 1 mile or so - I don't see what this has to do with any real world driving.

Ridgeline Mileage Testing. by eddiem

The testing data documented may be true on that stretch of road, but I can tell you that "real world" driving will yield very different and varied results. I was considering the Ridgeline, but bought a Dakota. It has a digital mpg readout, and I can tell you that reaching 20, 21 or 22 mpg is relatively easy, but only on a flat stretch, without acceleration. Try this. Reset your mpg meter to zero, and take your vehicle out for a drive. If the engine is cold, and you take off from a dead start, climbing a slight hill, you may see 9, 10, 11 & 12's in the readout. It is very easy to decrease your actual mpg with something as simple as slowing down and accelerating in traffic. As mileage (on the tank, which is when I reset the display after refueling) accumulates, that has a smaller affect on the "tank mileage", but it still affects it. Reseting the display on the highway will show you your "instantaneous" mpg, not your average over that tank or over several tankfuls.
I have 20,000 miles on my 07 4x4 3.7l / 6 spd manual Dakota Quad Cab, and I drive like an old lady, trying to maximize my mpg's. It's a game, but it is much easier to drop your mileage than it is to increase it on any given tank. FYI, my readout is about 95% accurate when compared to the fill and record mileage data method, so I know it's accurate. These numbers may only be "snapshot", not what you are going to get unless you take it out and empty a tank on a long (highway) run at conservative (less than 70 mph) speeds.

The figures in the graph are meant primarily to show the impact of speed VS fuel consumption.

My '06 Ridgeline with 60,000 miles gets about 21 MPG (US) HWY at this speed. The graph is about right for my experiences if I'm careful in acceleration. Keep in mind I have no roof rack and a tonneau cover on the bed. Tires are filled to max recommended pressure (checked and rotated regularly).
 
Driven hard the Ridgeline sucks significantly more fuel. Its all in my driving habits. As some indication of my conservative driving, I still have plenty of tread left on my OEM tires and "just" had the rear brake pads replaced.

That was imperial MPG, not US MPG. The imperial gallon is larger.

That is about 20.6 mpg to the US gallon.

You are right. I apologize. I read the wrong entry in the data.
 
And, 20.6 mpg to US gallon I would agree is an attainable figure for a steady, level 74mph (I think this was the speed in the graph.)
