Graphic: Shep McAllister

If you do your own oil changes, or would like to start learning, Walmart has several five quart bottles of Penzoil synthetic on sale today, and you can stack those savings with a $10 rebate from Penzoil. The best part? You can do the rebate entirely online, no stamps or licking required. Just double check that the bottle you’re buying is included in the promotion, and that it’s eligible for the full $10; some oil varieties have smaller rebates than others.
