The non-profit Consumer Federation of America has come out with a list of 10 ways to save on gas this holiday weekend and beyond. So what's new about it? The Federation tells us which tips save the most. Would you know if getting a tune up saves more than getting a wheel alignment? I would have no idea--in fact I wouldn't have known that getting an alignment can save even a drop of gas. And yet, an alignment saves twice as much gas as a tune-up, according to the CFA.

Here's a list of the ten tips. See if you can put them in order from saving the most gas to saving the least. Scroll down for the answers:
Replace your air filter.
Get a wheel alignment
Get a tune-up
Keep tired inflated to recommended maximum
Fix or replace a faulty or missing gas cap
Lose weight (and clean out the dead weight in your trunk)
