The last I heard, castrol is who makes arctic cat oils anyhow, so you may have gotten the same thing and not even known it!

Don't think so. Last information I have read on the forums is that the new (2002) Cat APV oil is made by Amsoil. The (2001) Cat APV was junk and caused nothing but clogged exhaust valves.
Also, Truimph is right, as long as the rating is the same it doesn't make much difference. Just be careful that you can mix whatever oil your using (syn. vs. reg).
Don't base your opinion of a certain oil based on what it costs. I have been using Amsoil (regular, the Racing is a waste of money) for about 2 years, trust me it is substantially less than what Cat wants for their APV oil. I went over 2000 miles without touching my valves, and when I did they were clean and slid right out. Its all in the specifications of the oil.
