After reading responses to my question about the 2.7 engine, I am curious about removing possible existing sludge. I think I now understand the problem with the timing chain of this engine.
The car I just bought has 27,000 miles on it. I have no idea if the previous owner actually changed the oil on a proper schedule.
One of the articles I read says not to add any type of oil additive that will remove sludge.
If I use a quality oil such as Castrol and change it within 3,000 miles, will the possible sludge eventually disappear?
Would I be better off to switch to Mobile 1 synthetic?
Thanks to all that responded to my previous post.
