synthetic is better in every way. It's almost the same price as conventional now. You can get 5qt jugs of mobil 1 at walmart for $25.

I recently sold a 2004 GMC Yukon that I bought new with 350,000 miles on it. It was purring like a kitten when the guy drove it away. Conventional oil all its life. Regular maintenance/oil change is the key and not so much synthetic vs conventional. 85% of it was Walmart $19.99 oil change specials after the free dealer oil changes ran out.

My 2021 F150 Owner's Manual calls specifically to use a Synthetic Blend

I use Mobil 1 High Mileage in my F 150. The previous owner used it when I bought it, otherwise I would be using Motorcraft synthetic like I do in My Excursion that has 350K on it

Synthetic is demonstrably better.

Like Cadcom said, main thing is just maintaining it.

Just me, but I wouldn’t change oil types in an engine that’s run that long without problems.

I agree. But it’s only better if you actually need that type of oil. Like octane in gas. If you don’t actually need super duper unleaded then you are just wasting money. Higher performace applications can make use of the synthetic properties/protections. Typical driver commuting to work and Home Depot on weekends - doubtful.

I have been a Amsoil and Mobil 1 user for decades. Even on my engines with higher mileage I get better oil pressure with synthetic oils. Filter choice is also important.
