I change my Amsoil & Toyota filter every 10,000 miles! Regular oil can go 5K on today's engines.

I do notice 1 thing now since my change yesterday.. about 6K afer the initial change i started losing oil pressure at idle. Well, that's due to so much crap in the filter!! ...it actually was clogging up the filter.


Related, possibly? Maybe even a little contradictory?

Maybe you should at least change your filter every 3,500-5,000 miles... Low oil pressure due to clogging can't be good for your 3.slo! <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
