I don't where you got this from, but thicker oil is definitely not always better on a modern engine. Thick oils in gasoline engines are better in performance engines if the machining and bearings are cut to have clearance for the higher viscosity oil. The standard 2021 to 2024 f150 5.0l oil viscosity is by design 5w30 if you deviate from this you will cause variable valve timing inaccuracies at a minimum. hydraulic valving for the cylinder deactivation not working at the correct time. This isn't the voodoo 5.2 l , it has the clearance and programing accommodate for that performance oil type.You have no clue what you are talking about. The 5.0 is rated up to 5w-50. If you think running a thicker oil is bad you are clueless. When towing and putting a heavy load on your engine it is STANDARD practice to run thicker viscosity to protect the engine. Anyone who thinks an engine is designed for one specific oil grade is clueless. In fact, if you put a supercharger on the 5.0 Ford says you would switch to 5w-50! Whether his noise is oil related or not, it is absolutely still beneficial to run thicker oil when putting a heavy load on the engine. 5w-30 is the minimum oil viscosity allowed in the engine. The minimum!
Side note my father builds engines and the bearing clearance is adjusted/ modified for the oil viscosity to be run if you do it right, even on the old school engines.
