[QUOTE="Norton, post: 16974913, member: 145307"] I wondered if someone would ask. LOL! At the risk of starting an oil debate... I like Amsoil because of the base stock and additive package they use in their Signature Series oils. That said, their SS 5W-50 shears less than Motorcraft's, yielding a higher viscosity. Amsoil's SS 0W-40 sheared viscosity more closely resembles Motorcraft's 5W-50 sheared viscosity. Putting all of that together, I've run Amsoil SS 0W-40, giving me (what I consider to be) superior base stock and additive package, along with correct viscosity for our engines, since ~2016. [/QUOTE]
