Gas Costs?

Due to yet another crisis, my husband and I are making one final move. We are moving from Las Vegas, NV to Eugene, Oregon.

I need to figure out how much to allow for gas money for a 91 honda accord. :) I'm also trying to figure out the shortest distance/time to reduce costs, as well.

I have no idea about gas costs as I live in China but I would like to wish you a safe and uneventual journey and hope you will be happy in your new home. Good luck!
