i have use regular oil for 200,000 mile.would it service any purpose to change to synthetic now.
Nope!
Agree;if the truck is runing smoothly and not using oil, you have maintained it well. No need to spend more on synthetic unless you are planning some heavy duty trailering or moving to Alaska.
Make sure you keep using the oil recommended for you truck, as shown in the OWNER’S MANUAL.

That is all bedrock needs to do.
I don’t see any benefit in changing to synthetic oil.
No purpose I can see. Keep doing what you’ve been doing.
