Looking at geting a used Nissian Quest what kind of MPG are people geting out of these things?

Hello I just purchased a used 2004 Quest with 48K miles. I am averaging 19MPG City and 20.5MPG on the Highway. It was getting a lot less MPG when I first got it. Then I put in a K&N Air filter. Also I don't think it helps that the van was fitted with Maxima wheels. They are low profile and wider than the original wheels. Wider mean more performance for cornering but your MPG's will take a hit. What ever wheels you have make sure you put more the the recommended amount without going over the Max. PSI. Good Luck

2002 w/ 96k miles... i'm getting ~19 mpg mixed driving

i dunno what generation are you going to get, but the 1st/2nd mercury villager counterparts have a non-interference engine...
