Yes, I'm not sure often, you need to check your maintenance schedule.

This is a great place to use Mobil One. I put Mobile One in my manual transmission at about 200K, and have changed it a couple of times since. The car now tops a half million miles, and I have done nothing to the transmission.

Good luck,
