Ok, I am going to give a look thru the archives as well - BUT while I am here - I know everyone has an opinion - I am just wondering is it really ok to run 20w-50 in my 3.0 during the summer months here in Tennessee?

A good mechanic friend of mine, who has greatly helped me revive a VERY sick 3.0, suggests 20w-50 in the summer and 10w-40 in the winter. His comment was just use a really good oil, avoid bulk oil at the quick lubes, something like Penzoil(his shop fave), and run it about 5000 miles between changes. His comment was that the Toyota filters are good enough, and the 3K mile thing is really only a concern when using crappy bulk oil. He had no opinion either way with synthetic or dino - as older cars can use either, and newer cars generally just require synthetic now because they ship with it.

I do trust him - ok - I am questioning this - <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> but 20w50 at 5000 miles is a FAR cry from the 10w-30 at 3750 the manufacturer suggests.

Thanks for the opinions and comments. - - Off to the archives....
