It seems that a lot of folks have some engine noise like piston slap, valve chatter and such using Mobil 1 because it is on the thin side. Some people's engines quiet down a bit when they switch to a thicker oil/different brand and same weight. What I'm asking is if an engine is making noise using Mobil 1 and then you switch to a(lesser) different oil even a dino oil and the engine quiets down does that mean the engine is being protected better then when using M1 even if it's a dino oil?
