MPG update on my new 2006 by thestormer
Dec 21, 2006 (5:36 pm)

I am the one who got terrible MPG on my 2005 EX.
 
I got a 2006 SE two weeks ago and just hit 500 miles.
 
So far, with 60% city and 40% highway, I've gotten 15.8 MPG city and 22.1 MPG highway, for an average of 17.47 MPG.
 
I know I need to "break" the car in, but this is extremely frustrating and disappointing already. I really hope the numbers improve over time.

2007 crv LX first 500 miles by 1crvman

First fill was 24.5 mpg, 2nd fill just under 27 mpg mostly interstate at 70mph or a bit faster(me driving) or slower(wife driving). Lot better that the '01 Tribute we traded for the CRV which had barely managed 21 mpg on same trip - but my 330ix BMW does 27mpg on same interstate trip (70 -75mph) and basically 19mpg around town, not bad for a six cylinder autobox that goes like skunk! I attribute BMW's mileage to aerodynamics and run flat tires that have those stiff sidewalls.
Too bad Ford/Mazda(Tribute)couldn't achieve better mileage as the basic design is sound but as usual after 6 years ownership the typical domestic problems arise which I'm sure won't present itself in the Honda. This is our 5th Honda over the last 24 years.

That's strange that you're getting that low of gas mileage on 2 different CR-Vs. What are your driving habits like? I have to admit, I'm pretty hard on mine. I tend to accelerate hard and go fast when I can, and I still manage 22 mpg in 80% city/suburb driving and 20% highway. I've consistently gotten this gas mileage even before the break in was complete. I now have 2600 miles on it. I don't know why you would be getting such low gas mileage.
 
By the way, how do you calculate your gas mileage? And how can you know what gas mileage your getting in each driving condition? I calculate gas mileage each time after filling the tank and can only estimate the total gas mileage, not for each driving condition.

Being totally subjective, of course, I tend to think I don't drive my cars "hard". I don't accelerate hard or fast and I try to anticipate braking and do so gently whenever possible. As I mentioned in an earlier post (#273), I don't get complaints from passengers.
 
When I got my new vehicle, it had a full tank of gas. I drove mostly city miles until my first fill-up. So I divided the number of gallons it took to fill the tank by the number of miles I drove up to that point.
 
After my first fill-up, I took a little road trip. It was mostly highway. While I was on the trip, I topped off the tank. I divided the number of gallons it took to fill the tank by the number of miles I had driven since the last fill-up.
 
That's how I was able to gauge the city vs. highway MPG.
 
Again, I really hope the numbers improve.

1. The dealer might not have filled the tank completely - disregard that tank.
 
2. You really need to take the tank almost all the way to "E" to get an accurate MPG. Shorter trips leave too much possibility of putting in more or less gas, and the smaller mileage driven enhances the possibility that the MPG will be wrong.

I didn't "see" the salesman fill the tank, but he had just gotten back from the gas station when I got there. The "needle" was above the "full" line, so I can only assume the tank was full or close to it.
 
2. You really need to take the tank almost all the way to "E" to get an accurate MPG. Shorter trips leave too much possibility of putting in more or less gas, and the smaller mileage driven enhances the possibility that the MPG will be wrong.
 
You don't have to take the tank to "E" to get an accurate MPG calculation. If you can calculate the exact number of miles you drove since your last fill-up, and you know the exact number of gallons it took to fill it up, you can calculate the MPG with reasonable accuracy.
 
This logic works when you always fill the tank completely. The distance driven since the last fill-up has no effect on your MPG. As long as you always "fill" it, you can calculate your MPG accurately.
 
I prefer not to wait until the tank is almost empty to fill it up. The last thing I want is to run out of gas.
 
So, here are my exact numbers since I got the car:
 
Drive away from the dealership with full or almost full tank: 174 miles on the odometer.
 
1st fill-up: odometer=372, gallons=12.534, MPG=(372-174)/12.534=198/12.534=15.797 MPG (mostly city)
 
2nd fill-up (top off): odometer=472, gallons=4.526, MPG=(472-372)/4.526=100/4.526=22.095 MPG (mostly highway)
 
**So, by your logic, I'm getting a lower MPG because I fill up before the tank is empty? Please elaborate, because I just don't get it.

I think the point about filling up on an empty tank is that there is a smaller room for error. Unlike my motorcycles, I do not fill the CRV right up to mouth of the filler neck....thus, a 2/10 gallon error on a 5 gallon fill up is much more critical for accuracy than a 2/10 gallon error on a 12 gallon fill up. Not much, but still a better possibility of an error. On a lighter note, I have checked the mileage on three separate fill ups..........23.75, 24.25, and 23 MPG. All are with a mix of local and highway driving on my '07 CRV AWD EX-L. I think the low MPG for city driving is due to the fact that the CRV weighs about 3500-3600 lbs without a full tank of gas, driver/passenger, etc. and is not as light as one would believe and only has 166 HP to motivate things!! I owned a 1998 Ford Ranger extended cab 4wd pickup that did not weigh this much!! It also did not put the smile on my face like the CRV does though.

I understand what you are trying to get across, but a possible 2/10 gallon "error", as you call it, is negligible in the calculation of the MPG and does not account for my low numbers. Honda claims averages of 22/27. I'm not even close at 15.8/22.1!
 
In addition, a 2/10 error would not occur in the same +/- direction every time. Essentially, for every 5 fill-ups, you would not have a "1" gallon error.
 
Over the course of time, and after numerous fill-ups, a possible 2/10 gallon error would be considered such a small number that it wouldn't even be a factor in the overall calculation.
 
My MPG to date on my 2006 SE is 17.468. My MPG on my 2005 EX was an overall average of 17.088. I arrived at this figure after adding up the miles driven up until my last fill-up (8358) and dividing by the number of gallons put into the car (489.112). If there were a 2/10 gallon "error", the difference in the calculation would be approximately +/-0.01 MPG.
 
My observations so far are preliminary, to say the least, and I was just expressing my hopes that the numbers improve over time. I am extremely disappointed because, although the car is new and not yet broken in, the numbers are SO low.

I think the point that partial fills will result in less accurate mileage readings has to do with the likely variations in the "fill point" between different fill ups. Those variations matter less when you average them over 12 gallons rather than, say, 4.
 
I just filled my new CR-V (1500 miles) today. My driving of late has been during cold-weather (25 to 45 degrees) and consisted of mostly very short, 3-4 mile trips. A nasty test of CR-V mileage, I'd say. The dash readout and my math reached identical results, 22.6 mpg. This mileage is terrible compared to our other car, a hybrid Camry, so I drive to maximize mileage.
 
On a 900 mile freeway trip, I was able to match the hwy rating of 28 mpg by staying around 70 mph. Good luck.

thestormer,
 
  I agree that the gas mileage on the CRVs is not great....our 2005 Altima 3.5 with 250HP is 23-24MPG locally and 28-30MPG on a trip and that car rips!! It also weighs only about 250 lbs less than the CRV. I also own a '04 Honda ST1300 sport touring motorcycle and the MPG is 10-20% less in the winter while using the winter blends gasoline....I am hoping the CRV does better with a few miles on it and when the gasoline is not the winter blend.
