You have no idea!Talk about OCD! I hope these are the biggest problems in your life!
What you describe here is an older way manufacturers calculated and presented "range to empty". Honda does it differently, in that if you are driving under conditions that improve mpg for you... Honda simply holds the "range to empty" static until it's calculation at improved mpg is reached, then it will begin to tick down again. You can over ride that I think by turning off the engine and restarting (though I have not actuyally checked that on a gen5). I have literally seen my CRV keep the "range to empty" static for as long as 50+ miles. In my case that is when I am taking a long trip after my more normal weeks of short trip in town driving.The range calculator on my old Nissan was just the opposite. It would show an available range of well under 300, usually 271 or 268, upon starting the engine after filling up. Then as I burned a gallon or two, it would recalculate and increase the number accordingly. It got much more accurate as the tank became closer to empty. I once got 560 miles on a single tank while hypermiling. Actually I went through six tanks in a row of 500+ miles back in 2014.
Yes, I realize that. Both the Nissan and Honda operate the same in this one respect. However, after filling up and starting the engine last night, the CPU is calculating the available range based on a 14 gallon capacity. When I saw the number, I believe it said 371 or 389, I don't remember, but it was inflated. Realistically, I don't expect to get any number above 320-330 on my current tank, since I'm only going to be able to use 12 of those 14 gallons before returning to the gas station. 12 gallons at 26mpg would bring me to 312.when you stop to refuel and then restart your CRV on a full tank.. the CRV uses your last fuel economy calculation from before you stopped at the fuel station as it's metric to calculate "range to empty".
The 14 gallons isn't a constant, that was just for that fill. I've seen that value range from 11.6 to 15.6, averaging around 13. I suspect the mpg used to estimate range to empty is over a couple of past fills rather than the one just observed....However, after filling up and starting the engine last night, the CPU is calculating the available range based on a 14 gallon capacity.
Is this on a gen5 CR-V? Based on anecdotal data, it seems rather consistent that the listed 14 gallon capacity in the owner's manual is accurate and cannot be exceeded like in some other vehicles. Have you actually pumped over 15 gallons into the tank of a 5th gen CR-V without overflowing it and without some of the fuel getting sucked back into the pump?The 14 gallons isn't a constant, that was just for that fill.

What you are seeing in the discussion is the normal variation results from pumping with auto shut-off on the fuel nozzle. Depending on the rate of flow from the nozzle.. there will be some variation of how and when the auto-shut-off triggers. Fast pumping is likely to trigger the shut-off sooner then a more moderate flow from the pump. This is completely dependent on the fuel dispensing pump at the fuel station and has nothing to do with the CRV (other then possibly the design of the down pipe that takes the fuel).Is this on a gen5 CR-V?

To clarify, the calculation ranged from 11.6 to 15.6 for my history on a 2017 CR-V AWD, EX-L over 85 fillups I had pertinent data for. I was merely pointing out that while your one reported instance showed the car's calculation matching the spec'd tank capacity, it was a coincidence, not a constant value.Is this on a gen5 CR-V?

This tracks well with my experience too. The way the fuel alerts are set by Honda, they want you to refuel when you are at about 2 gallons remaining (which some owners gripe about.. but Honda, and frankly most manufacturers, consider to be "fuel reserve").As I posted in the previous similar topic, I have never put more than 11.8 gallons in the tank utilizing the pumps' shut offs in over 100 fillups.
Yes, I've definitely noticed this on multiple vehicles for many years.Fast pumping is likely to trigger the shut-off sooner then a more moderate flow from the pump.
Agreed on all points, but my gripe is that the 14 gallon capacity is simply too small. How much does a gallon of gas weigh in pounds? Maybe 7-10? If they increased capacity to 17, it would add at most 30 pounds of weight while substantially increasing range per fill-up. I would also gladly sacrifice a couple cubic feet of cargo space for this benefit if necessary (but not the spare tire, LOL).This tracks well with my experience too.

"Baking in" a fuel reserve in the fuel indicators is prudent practice in my view. Otherwise.... manufacturers get a different kind of complaint about high maintenance costs when the owner thinks they can get just a bit further before refueling and then run out of gas and the fuel system is damaged.
A gallon of gas weighs ~6 lbs +/- some variation due to the components in the blend. Hehe.. winter fuel with butane should be lighter... right?Yes, I've definitely noticed this on multiple vehicles for many years.

Point taken, but I think those small side areas behind the wheels are a waste. They also make the dual-level adjustable cargo floor board a little awkward when its in the raised position, since they sit lower, but they sit flush with the floor board when it's in the lower position, making the small plastic dividers unnecessary in that position. I wish they had used that space to put a subwoofer on one side (on all trim levels) and increased fuel capacity on the other. I'm just venting. I know no car is ever going to be perfectly designed according to my personal preferences, at least not at the price point of a typical non-luxury name brand vehicle.Realistically, most vehicles fuel capacity is designed around the expected low end mpg of the vehicle in conjunction with calculating and applying a generally acceptable range-2-empty capacity. In other words... the designers balance the space required vs the range-2-empty to meet the broadest set of owners needs/wants. Of course any population of owners has variation in preferences and wants.. but they try to dial in for an solution that can please the most, and ignore the corner case owners.
