Brant Ontario, Canada | Lots of people buy those trucks, take them to 12,000km(7500mi) on the factory oil and have zero problems ever. That is the regular duty service interval for those trucks. Severe service is 8000km (5000mi). Have not seen one 6.7L engine failure from anyone following Fords schedule, and only seen one 6.7L be replaced at all since the launch.
Just do what your owners manual says and everything will be fine. | |
