Yeah, I understand the urge for quick satisfaction (that's why I call most of the useless OTC additives "satisfaction-in-a-can").
If the root of the problem is mechanical (e.g. typical Saturn engine oil burning issues due to stuck oil control rings), the only way to resolve this is to take it apart and deal with it (scrape the carbon off of the ring lands, re-ring, etc.)
My 2c's worth.
Q.
I agree. BUT! If you have one car, it's your daily driver and it's Dollar value is low. You may not be able to have the car out of service or be able to afford, or be able to justify, the expense of a rebuild.
Many years ago I was in such a situation. In my case a can or two of STP reduced oil consumption to a manageable level, so I was able to get to and from work, pay the mortgage and eat.
In an ideal world we would all have new cars, perform regular OCI's with quality oil, and our car would not have inherent defects.
In a less than perfect world, oil Thickeners and engine cleaners can (IMHO) play an important role.
