My old Saturn 2003 Ion still runs good. I love the Ecotech engine. I don't know how dirty the engine might be. It has 107,000 miles.
I will give the Pennzoil Platinum (or Pennzoil Ultimate if I can find it) a try. If it turns really dark I will assume that the engine is somewhat dirty and maybe use some Lubegard engine flush the next oil change before changing the oil.
I say make it simple. Try a good cleaning motor oil and if that is good enough then it is good enough. Look at the photographs above-the Pennzoil Platinum seemed to clean pretty well.
If you buy a used car or truck that has been nelgected by the previous owner, you might have to drop the oil pan and the valve cover(s) or overhead cam cover and physically clean the engine and then use a good cleaning oil.
Or use MMO, Kreen or Neutra with a good cleaning oil like Pennzoil Platinum.
We probably already have good enough cleaning techniques except for the most nelgected, old, and dirty engines.
