RTP2017, just out of curiosity, how does your trip computer compare to your calculated fuel economy? Over my first 1,000 miles, the trip computer has averaged 1.8 MPG higher than the manual calculation. I'm wondering if you're seeing a larger discrepancy. If so, have you double checked your manual calculations?

^^^ Eggszactly.

As I stated earlier, people tend to lie (by addition or omission either maliciously, accidentally, or due to ignorance) and/or exaggerate to impress the world or themselves. That's why I generally disregard reports from "Chicken Littles" complaining about only getting 12 MPG or bragging about getting 28 MPG - those are outliers. By now, there have been enough Fuelly reports to establish reliable enough data that individual reports can be dismissed. According to real-world data, the 2017 averages 4 MPG more than the 2014 so far - which matches my personal experience.

4mpg is quite high if thats actually true. Computers are misleading quite large margin then. However would you then feel that RTP2017 computer is just being honest or there is something odd going on because ultimately thats what we are trying to do. Lol perhaps his computer is under estimating and mine is overestimating. I think its perhaps a little low or again maybe he has one honest computer reading.

It's actual and it's factual. Here are the actual fuel economy calculations for my 2010, 2014 and 2017 Ridgelines:

Also, I document what the trip computer reports in the "Note" field of each fill-up. That's how I know the trip computer in my 2017 reads 1.75 MPG higher than actual.

EDIT: My 2017 is actually averaging 4.8 MPG more than my 2014, not 4 as I stated earlier. I was rounding down based on the historic fact that the fuel economy in every vehicle I've ever owned tends to go down after the new wears off. It never recovers or increases after it is "broken in" or has its first oil change. My best fuel economy is achieved in my first few tanks before it decreases a bit and levels off from that point forward - and I've got records to prove it.

Interestingly, my 2010 Ridgeline was rated at 1 MPG less, but averaged 0.3 MPG more than my 2014 Ridgeline.

hand calculated on a tank, BUT not in normal driving. My sole purpose is to get 30+ ... I am not talking hypermiling, just driving with no traffic or bad weather

Assuming you're not joking, I truly don't believe that's possible. Over a several-mile stretch of flat, straight FM road at a constant 55 MPH, the highest I've seen on the trip computer is 28 MPG, which is about 26 MPG for me. I'm not a betting man, but if I were I'd bet you a hefty sum you can't get 30 MPG out of a tank.
