I don't think I know a single person who has worn out their engine prior to wanting a new truck. If you think you have to change oil every 5000 miles I sure would't waste money on synthetic.
There is no commonly available dino 5w-40, or 0w-40.
What do we use if we need 0w or 5w cold?
The problem is not just wear, but cold enough, dino just will not pour or start without supplemental heating.
Synth 0w or 5w extend the range considerably.
If you need the light weight oil put in synthetic but dumping synthetic at 5000 miles is like replacing your tires when there is still 3/4 of the tread left on them.
