Default switching to synthetic
I already have Royal Purple in the trans and rear...and i am puttin5w20 in the engine.......for the first initial switch to synthetic, should I do anything different like change oil soon after the first time for just the second time to get the little mix of old oil and new synthetic out or will it hurt anything.?
Thanks

You will do fine if it was syn before you added that kind....why switch to rp just cause all your other fluids are that?
