I have it in the VX, my Jeep, and my wife's Jetta... next up is my motorcycle (Yamaha R1)

Amsoil says 12,500 or 6 months filter change and 25,000 or one year full oil change with and Amsoil filter.

7,500/6 months filter change and 15,000/one year full oil change with Hastings or comparable filter.

After I sell my Jeep and have some money, I will be changing all the fluids in my VX over to Amsoil synthetic.
