I added synthetic gear oil to mine, will that screw it up? Has anyone had problems with synthetic gear oil instead of ATF?

My father got the gear oil from his work, he said it shouldn't be a problem. Why is a thicker syn oil worse in the manual transmission then ATF? What difference does it make?

----------

I have ATF that replaces MERCON, would it be ok to use the substitute? And my rear diff is not a Limited slip, could I use the gear oil there?

Because the M5OD has tight tolerances and gear oil can't do the job right

It is a conspiracy by Ford to make more money. Gear oil is cheaper then Mercon. They want to sell more Mercon The "con" in Mer-con is a hidden symbolic meaning for the con-spiracy!
