Sorry, this offer has ended. Take a 7 question quiz in the Motor Oil Matters Game and at the end you can select a $10 Shell or $10 Jiffy Lube gift cardto be mailed to you. It’s an easy quiz and you don’t have to get all the answers right (but most of them) to pick your gift card. Take the quiz again if you need to improve your score to fill out the form at the end for your gift card. Expect your gift card to take about 6 to 8 weeks to arrive in your mailbox.
