Fuel Economy Went South Suddenly
I have a '98 Odyssey EX. Over the last month or two, it has gone from
25mpg highway to 20. It's nothing obvious like a disconnected spark plug or an underinflated tire. Any guesses what it could be? |

It did get 25 on the highway, but only on long trips when it was driven through entire tanks of gas (> 300 miles) without stopping. How long have you had this car? Do you have enough experience with it to know the 25 mpg wasn't just a fluke? |
