Understanding Your 2018 F-350 Super Duty
The 2018 F-350 Super Duty was part of the fourth generation of Super Duty trucks, introduced in late 2016. It retained the choice of either the 6.2L SOHC 2-valve V8 gasoline engine or the mighty 6.7L Power Stroke V8 turbodiesel engine. Both engines are paired with a robust 6-speed automatic transmission (TorqShift). This generation saw significant enhancements in terms of aluminum body construction (saving weight and increasing payload/towing capacity), a stronger frame, and more advanced technology. Understanding your specific engine and its requirements is paramount for effective maintenance.
