Frenchie,
Sorry for your loss but thanks for keeping us updated. I hope that Amsoil has done more to notify people of this issue. At my last oil change back in May the auto parts guy (a good named place) advised me of using Amsoil exactly as you described. Being uncomfortable of this I did not, unfortunately I might have had the same results as you. Me being kida wary on a 10,000 mile oil change I opted out and am glad I did. Maybe I'd be fine but now I know that 5,0000 is the limit great oil of not. 5000 miles NO MAS (no more)- MAS CERVEZA

ok amigo; but no more miles!
