low highway mpg
Hello, I'm new to this forum. I just registered. I'm wondering if any of you can help me with this?
I have a 2011 compass and wondering if anyone else experiences this phenomenon. All factors being equal, correct tire pressure, using gas from the same station each time, no extra cargo, alignment okay, no A/C, etc. I get about 26-27 MPG in the city (freeway and city streets). But, when I've traveled from Orlando, FL to Savannah, GA the past 3 times my fuel mileage goes down, that's right goes down, to 24-25 MPG. The dealer can't find any codes in the computer or any malfunctioning parts. I've never owned a vehicle that gets lower MPG on the highway than in the city. Has anyone else experienced this or can tell me what might be affecting the highway MPG like this?
