Buried about 8000 words down in another thread is a discussion about my work on how much additives you need to add to your engine. http://sterkel.org/avanti It is peer reviewed work for another forum. Those in that forum know the background, but I do not think I mentioned it here.
My bottom line:
If you use CI-4/Plus oil with TBN>10, Zinc>0.12%, Calcium>0.20%, you are fine. You may have a viscosity issues north of the Mason-Dixon line during the winter and need to look for something <"15w-xx".
I have documented in this forum several oils that easily meet these criteria, and are available, though not in big box and/or auto parts shops. I will not repost, as I am trying to break my bad habit of cross-posting.
I am categorically anti- "adding additives" for many reasons.
However, not really being an iconoclast, I do realize that people may not wish to mail order oil like I do, or have a convenient NAPA. In that case, and to be helpful, I have peer reviewed an approach to most-economically add additive products to zinc-deficient (for our engines) but otherwise excellent oils. I researched the current crop of additives, and found that most are 50 weight oil with little useful in them, or have deeply controversial inclusions. However, a few that may be helpful to "fix" otherwise excellent zinc-deficient oils. The VOA of each is documented. What is presented is the maximum number of ounces you need for each of the "fixing" additive products. I have also documented a sample of oils that for whatever reason, I have been recently interested in, including the Maxlife group.
If you wish to play your own tribiologist. http://sterkel.org/avanti is one peer-reviewed approach.
