What would be the best synthetic oil to use in a high mileage engine?

Should i continue to use the originally recommended mobil one fully synthetic or should i be switching to a special brand that would serve the engine better due to its high mileage?
I have currently clocked 245,000 miles (
394,289.2 km)8)

Many thanks in dvance to those who respond

Hi Doc , i have a 2005 full size vehicle ,4.4l bMW M62TU Engine , I love it.
When i got it it had been through 5 different owners and all of them gave up on it , the most annoying issue according to them was the terrible noise from the lower windshield seal so i bought it cash and fixed ll the minor gremlins and its been pretty good since then. At the time it had 80k miles (2012)
Very cool to see, thanks! I just switched from Mobil 1 Extended Performance 5w20 to AMSOIL Signature Series 5w20 in my 5.0 NA V8. My oil change interval is every 7,000 - 10,000 miles depending on type of driving.

I switched to AMSOIL mainly due to its lower volatility (NOACK < 7%); hoping it may help lower the carbon build-up a bit.
