SmellSoGood Posted September 12, 2009 Report Share Posted September 12, 2009 Hi, I've been a Mobile-1 0w-40 fan for the last 8 years on my twin-turbo. What say you on oil products and viscosity numbers for the 5.4l engine on the Shelby - recommendations? At pickup today, I opted into the Ford ESP Warranty plan to give me 5/75,000 coverage. This includes 5k maintenance (rental, oil, checkup, etc.). What does Ford stick in the Shelby? Link to comment Share on other sites More sharing options...
