Also, would you mind sharing the Blackstone report. I'm sure the guys on the oil forum (link below) would love to comment on it.<ul><li><a href="http://theoildrop.server101.com/cgi/ultimatebb.cgi">oil forum</a></li></ul>

Both Mobil1 0W40 and Amsoil 0W30 are rated to 10K mi, Amsoil to as much as 16K for normal driving purposes, or 6 mos - whichever comes first.
I still change my Amsoil every 5-6K regardless.

I'd post the report itself, but it's in Adobe format, and the pic poster doesn't like that. Plus, I don't have any hosting abilities. Sorry.

Amsoil isn't cheap, so maybe you could save a few bucks in the long run if the oil is still in good shape.
