Following is an interesting site I found that not only discusses oil, but other aspects of the car:

I found one thing on that site that already made me not trust it, it saaid Toyota has more sludge problems than any other, infacy it is Chrysler that has more sludge law suits,complates, problems, or what ever than anyone else
