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.

Replying to: thestormer (Dec 22, 2006 1:10 pm) 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.

Replying to: thestormer (Dec 22, 2006 3:44 pm) 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.

Replying to: lzc (Dec 22, 2006 3:52 pm) Hypothetical example: Every time I fill up, I get 5.000 gallons. In a previous example, a 2/10 gallon error would indicate I'm actually getting 4.800 or 5.200 gallons. This might affect the MPG in a very small manner on EACH fill-up (1 MPG or less), but over time, the MPG will NOT be affected in any negligible manner (+/-0.01 MPG at 8358 miles). The best method I can think of to calculate MPG is to take the overall miles driven and divide that number by the total number of gallons put into the car. Any so-called "errors" will average out in the long run, so I just can't understand how that can be held as a valid argument. Again, I only listed my preliminary numbers as just that: preliminary. I know that my average MPG will change over time, but changing from my current numbers to the Honda numbers seems like quite a stretch. Even if I agreed with the "partial fill" argument, I don't understand the large discrepancy in numbers. Any "variation" in fill points does not explain why my numbers are so much lower than 1) Honda's claims and 2) others' averages. If my averages, so far, were 21/26, I wouldn't be disappointed. I'd actually be pretty happy. Instead, my numbers are 15.8/22.1. So, I don't understand how any slight "variation" in fill points can account for a difference of 5 MPG. **So, again, I'm getting a lower/LOW MPG because I fill-up before my tank is empty?

Replying to: greenteacrv (Dec 22, 2006 4:04 pm) My 2005 EX got terrible gas mileage as well and I drove that year-round. I looked at my spreadsheet and there was no significant variation in MPG from one season to the next. So the winter blend really didn't have a huge impact on my numbers. |

Replying to: thestormer (Dec 22, 2006 4:36 pm) I agree. However, one must be fastidious in recording the data!  tidester, host

Replying to: tidester (Dec 22, 2006 4:46 pm) Every time I get gas, I get a receipt and write the odometer reading on it. I then enter the info into a spreadsheet. I get the MPG per fill-up and the overall MPG since I got the car. |

Replying to: tidester (Dec 22, 2006 4:58 pm)  Btw, for consistency, I try to call it full when the automatic pump first clicks off (although it hard to resist the temptation to cram another quarter's worth of gas in there). That'll help avoid check engine lights too since there's less risk of getting gas or vapors into the evaporative system.
