shifting 1st to 3rd to 5th won't help you save gas... just keep your rpm's lower and in the power band so the engine doesn't have to work hard... If you're bogging it down when shifting from 1st to 3rd you're using more gas than you need to and if you wind it out in 1st to get to where you need to be in 3rd you're wasting gas...
