2000 Accord EX - giving only 25MPG :-{
My 2000 Accord EX, 5-Spd, 55K, Boston, used to give 30-32MPG. Suddenly
this winter I noticed that it is giving only 25MPG. Can someone tell what could be the reason. I do regular oil changes and nothing else, so far. Please advise. |

I have an 04 EX with 42,000 miles and I also noticed this winter that
my mileage dropped from about 33 MPG (half city/half highway) to about 29. I figured it was the harsh cold/weather in the Philly area that I live and drive in. I am waiting to see what spring/summer has in store. |

Without actual mileage numbers and actual fuel used we can't do the math. How many gallons of gas were left in the tank before and after the fuel change before filling up? Did you take 13 gallons to top the tank after 5 trips before the change and 11 gallons to top the tank after 4 trips after the change? Mileage is computed by taking the miles driven since last fill up and dividing by the number of gallons to refill. Not by approximating how many "70 mile trips" before the needle left me believing I couldn't do one more trip before filling up. Heck, each on of those weeks of trips could have had a different number of trips to the grocery store in between fill-ups that would have also skewed the numbers. |

When the gauge reads empty it's empty. I always refueled at the same point. 5 trips down to 4 is 20%. |

Exact same number of litres in each fillup? Wow! > I always refueled at the same point. 5 trips > down to 4 is 20%. Only those trips? Nothing else? Same weather too? Wow. |

You stalled and had to be towed to the gas station? How much is left in the tank at each fillup does change in size. Your method of computing gas mileage is about as accurate as having the waiter read your tea leaves to determine the check. Today when I filled up, the car took 14.7 gallons. The odometer indicated that it has been 347 miles since my last fillup. Now we have some math to do. That works out to 23.6 miles per gallon. Do that a few times in a row to get a better/consistent winter average. Do the same in the summer. Now you have a comparison. Your method does nothing to compensate for how much actual gas was used. One fillup maybe 12 gallons used, another 13, the next 11. Your also counting just "trips to work of x miles". While it's possible that you don't use your vehicle for anything other than commuting to work, it's more likely that you sometimes hit the grocery store, drive out at lunch time, run an occasional errand. |
