I think the new stuff is rated to like 100K miles. I wouldn't bother with it until 50K at the earliest.

I do it every 2 to 3 years. I run my truck hard during the summer and it sits in the garage during the winter.

You shoulden't need the pellets unless you are experiancing a small to moderate leak. If you need them this is the GM part # 3634621
