  1. I basically just got used to the sound so I don't even notice it any more. I'm assuming it just annoys some people more than others.

    MPG Happy Talk

    Highway MPG seem to be getting better with age. 2 years ago in May we drove from Michigan to Colorado and back and averaged 42 MPG. We just got back from a trip to Washington DC and this time we averaged 47.7 MPG. I can't really claim that it's my driving because I mostly just set ECO cruise to 70 MPH and enjoyed the ride. Temperatures were mostly in the 60s on the ride out so we didn't use the AC. On the way back temperatures were in the 70-80s and I had the AC set to 72.

    Trips

    Road trips
  4. I've been recording Fuelly MPGs for over 2 years and the Fusion computer reports 5% better MPG on average.
  5. I had the rear middle seat-belt locked up for many months (maybe even since it was new). Every time a passenger tried to use it they couldn't because it would not pull out. When I took it to the dealer for the 30,000 mile oil change and tire rotation I asked them to also fix the seat-belt. I went to show them how it was locked up but it worked perfectly fine. I'm sure it will re-occur soon. At mile 36,001.
  6. I went with one of these: http://www.amazon.com/gp/product/B004E3RE5I/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 I just made a 400 mile trip and it worked great. There are 2 slotted holes in the trunk lid that I used for the lower strap clips. I'm not sure if that's what they're for or not but there was no sign of damage or denting anywhere. A disadvantage of a trunk mounted bike rack is that the bikes are held higher than with a hitch mounted rack and therefore probably affects the car aerodynamics more. I took about a 10 MPG hit.
  7. I have 15 months of keeping track of fuel economy on my 2013 FFH. My winter MPG are more than 10 MPG worse than my summer MPG. I got the update as soon as it came out and did not see much difference. On the bright side, the MPG this winter are very similar to last winter. But since this winter is so much colder I figure the car has improved (maybe software, maybe break-in, maybe both).
  8. I find it interesting that your chart is very similar to mine. What it tells me is that the software update and the break-in miles had very little effect on cold weather MPG's.
  9. Please post your 1 year fuel history if you have one. It might be interesting if any conclusions can be drawn. One thing I'm concluding from my history is that what I thought was better gas mileage due to getting past my break in miles and finally learning how to drive a hybrid to maximize fuel efficiency, was nothing more than seasonal temperature changes. I'm not complaining though. 40 MPG average for the year is not 47, but it's darn better than the 24 MPG I was getting in my Jetta for the previous 10 years.
  10. Your average for the round trip was NOT 45 MPG, it was only 40 MPG. If the trip was 20 miles one way (distance does not matter, the result will be the same) you used 2/3 gallon (20 miles / 30 MPG) to get to lunch. On the way back you used 1/3 gallon (20 miles / 60 MPG). Your total fuel consumption was therefore 1 gallon. So your MPG for the trip was 40 (40 miles / 1 gallon).
  11. I reset my lifetime average in May when I started getting better gas mileage. Until about a month ago it was 48.9 MPG. It is now dropping like a rock and is down to 47.4 (most trips are in the mid 30's MPG). When I was getting excellent mileage during the summer, after being quite disappointed all winter, I had no idea if it was mostly due to the car break-in period, the software update, learning how to drive a hybrid, or the warmer temperature. Well I'm now convinced temperature is a way bigger factor than any of the other variables.
  12. It's my personal opinion that Ford could easily make the fuel usage calculation a lot more accurate. Every FFH seems to be skewed by 3 or 4 percent. The problem is that they have no motivation to do so. The skewing is in their favor and there are no regulations that require them to have a certain degree of accuracy (unlike gas station pumps).
  13. I was not aware that it was well established that the FFH under-reports miles. I have not done a careful study on mine but I do know that the MPH reported by my FFH and by my GPS (going at highway speeds) are within a fraction of a MPH of each other. Would this not indicate that on my vehicle the miles are not under-reported, just the gallons?
  14. Yes, but the trip computer would also think that it had traveled 4424.6 miles instead of the actual 4337.8 miles and therefore it would have reported (4424.6 miles / 98.59 gallons =) 44.88 MPG and NOT 43.00 MPG. Still off by the exact same percentage. It does not matter how inaccurate the odometer is, the MPG discrepancy, as a percentage will remain the same.
  15. Odometer accuracy does not really matter because both the spreadsheet and the FFH computer are using the same odometer miles. Let's say that the odometer is off by a factor of 2. So instead of traveling 4400 miles you actually traveled 2200 miles. All that means is that instead of of 42 MPG (spreadsheet) and 44 MPG (FFH) it was 21 MPG and 22 MPG. The percent difference in fuel usage remains the same.
