For this month, Advance Auto is running 5 qts Mobil 1 w/filter for $30 after $5 rebate. Of course they don't have the filter for the Crossfire, but I have two other cars to use the filter. Two specials will get you enough for an oil change plus a quart extra and two filters for $60 after rebate. Good Deal.
