If you follow the first link and use coupon code DOW9 you can get Shell Rotella T6 5w40 for $16 a gallon. Make sure to choose which store you want to pick it up at. If you want to get another $5 follow the second link and fill out the rebate. The rebate is limited to 1 per household.
This should get the upcoming season started. I bought 3 gallons myself which takes care of my oil needs this season
