Yes, you can mix full synthetic gear oil (like AMSOIL SEVERE GEAR and Long Life Gear Oil) with conventional and they are generally compatible with each other. However, mixing synthetic and regular gear lubes can shorten the oil's life expectancy and reduce performance, which is why AMSOIL does not recommend it nor support extended drain intervals where oils have been mixed.
