I see consistent results with LM Ceretek. I have experience building a few engines over the years and I’m not easily fooled. What I consistently see is a smoother running engine, less vibrations and smoother idle, less cold start valve clatter, and improved MPG. I’ve seen this in multiple applications over the years, but the interest in doing the UOA is to see what’s going on with the metals primarily, and if the product is actually making any changes to the chemistry for the negative. So far, I’ve yet to actually see this. The next UOA of course will be without any additives. I generally run it every 15k - 20k miles.
Lake Speed Jr does a good video where he pretty much trashes most oil additives and I agree with what he’s saying, but it’s interesting when he gets to the two different LM products he pretty much skips those. My iron is a little elevated, but as I mentioned this is pretty early in the break-in / flushing out period. I’m actually impressed the oil did not drop to a 30 grade over the 2900 miles. Right on the edge but it held up. This truck sees a lot of short trips / city environment, miles don’t tend to come too quickly. Larger view of the UOA, you can see after 3k miles the additive packs are very strong. The truck is also tuned and running e40 - e50 fuel, another reason why I wanted to do this OC a little early as fuel dilution was a concern and it turns out I don’t have any. I just started to use an upper cylinder lubricant in my fuel and a good amount of research, TCW3. It will be interesting to see the next UOA.
