Engine Noise & Oil
I'd never be one to really admit to this having always kinda scoffed at people on the internet arguing back and forth about what brand of oil is better, etc... but after changing my oil the other day in my 2019 3.5EB and putting in Castrol Edge 5w30, Omg is the engine quieter and seems to idle with so much less vibration. Before it was just kinda.... thrashy sounding, started when I had the dealer change the oil - NVH was so much more noticeable that I checked the oil level as soon as I got home, thinking it was severely underfilled from the Dealer. Welp, AINT going back to them!
In the meantime, is there a common oil the Dealerships use for oil changes? I cant imagine they are dumping Motorcraft in. Probably whatever bulk oil they can get their hands on cheaply??
