With all do respect to everyone's choices, I have been guilty plenty of times of doing similar stuff without researching it. Hype works, that is why it exists. Even the best of us fall to hype.
As for Lucas, it has been analyzed many times and is simply heavy mineral oil with no additives. So while it may have an effect on a tick or something else, all you are doing is adding viscosity to your oil while diluting the additives. Now, if you added some 20w50 with additives, you would be doing the same thing but you wouldn't be diluting your additives.
I explained motorkote back on page 21, again unless you know what is in the additive and understand the chemistry then why would you dump it in your truck? If your oil needs something for it to do it's job, find a different oil. If you are using a top shelf synthetic oil, even group 3's, an additive is likely going to make your lubrication worse not better. Maybe it will release some friction, but at what cost??? With all do respect to truck drivers as I was one for a decade, we are not scientists and most of us aren't educated past high school which is why we drive trucks in the first place. Wasn't til after I drove a truck that I was able to finish college. So saying truck drivers use something so it must work, doesn't past my muster.
Now, some additives like Prolong made a hit on the market place and those of us who used it where amazed. Prolong contains chlorinated paraffins which experts in the oil industry believe to be unstable and corrosive when exposed to heat. Many oil guys hypothesize that is what motorkote is, don't take my word for it google VOA and Motorkote and read all of the posts. If there is Chlorine of any kind you don't want to put that in your truck. Dump it in your swimming pool if you like, but not in your truck.
Last thought on additives, perhaps there is a place for some on the horizon for a very few applications and the hemi just might be one of them with all of the challenges we have with lubrication. But oil thickeners are not good because you can achieve the same thing without sacrificing additive dilution. And if an additive doesn't disclose what it is, why dump it in your truck? It could be a prolong clone, it will make your truck sound awesome and hyper clean your engine, but also can and will cause damage to your internals.
An example of an oil additive that would be beneficial would be something that doesn't corrode anything ever (so anything chlorine is out) and is oil soluble and reduces friction. However, oils already use such products and they are calcium, Zinc, Moly, phosphorus, boron, etc. And soon as another additive is developed to give benefit to an engine the oil industry will absolutely include it in it's formula as soon as they can.
I keep an open mind, but you have to convince me with science not hype. I'm past that. I promise ya'll I will be the first to say I'm wrong if you convince me with science, not only tests but tell me what the product is so I know it is not a chlorinated paraffin. There is a reason that no oil company adds that crap to any of it's oils.
Hemi tick is a *****, makes you want to dump anything down there to see if it helps, I am so guilty of this myself! But treating sticky lifters and the expense of your internal bearings isn't worth it. I don't think having a little thicker oil is a bad strategy, I would mess with that right up to the point you get a CEL. Maybe add 5 qrts 5w20 and 2 5w30 or something like that. That would be the same thing as adding lucas but without the foam.
Research what ya'll are promoting and then let's have a conversation about it.
