When can I switch my remanufactured 4.0 shoc to synthetic

[donalds]

New remain 4.0 has 1700 miles on it when is the best time to switch some reman companies say 5000 miles seems like to long

 

[Tech By Trade]

Soon as you fire it up. Usually a good idea to run dino for 500 miles then change it to clear assembly lube.

First oil change will be fine as said above.

 

[donalds]

To be on the safe side I changed it at 100 miles
600 miles still on dino I'm gonna switch at 3000
Oil change unless it would be better to do it sooner

Won't hurt to wait to the next one

Thanks just like the way it sounds on synthetic more smooth

Did not want to f up my new engine it's cherry

 

[Mbrooks420]

I highly doubt it has any effect on how it sounds.

 

[donalds]

The old one definitely sounded better at idle no doubt in my mind
Now the new engine may be no difference Idk we will see

On a freshly rebuilt engine I'd probably replace the dino and filter are around 500 miles out of an abundance of caution. I'd probably switch to full synthetic at around 3000 miles. By then any breaking-in will have happened. The main breaking-in that occurs is for the cylinder rings.

Just what I was thinking
