The recommended oil weight for a 2007 Ford F-150 with the 4.6L or 5.4L Triton V8 engine depends on the climate where you live. Ford generally recommends
5W-20 for most conditions. However, in extremely hot climates,
5W-30 might be suitable.
Always check your owner's manual. This is the definitive source for the correct oil weight and type for your specific vehicle. The information printed in the manual considers factors beyond just the engine type.
