i resently installed a 12 bolt rear end in my car but i filled it with royal purple full synthetic oil and i forgot to read the break in instructions on the rearend it said to fill with non synthetic fluid what do i do drain it and fill it with conventional or do i leave it as is help me guys

 

What to do..........hmm...........let's see........OK I got it. Not posting drivetrain questions on the engine tech forum would be a start.

Drain it and put the dino oil in. And if it has an Eaton posi never ever use synth.

Moving this to the drivetrain forum.
