That's another concern I have with the theory. How does it affect the detergent action of the oil? IDK. I'll start shopping for additives the day I see a clear performance deficiency with oil straight out of the container. The stuff is expensive enough to start with.
I started driving 40 years ago. I agree that Penzzoil may be completely different now. The specs were lesser back then compared to other brands. I haven't checked lately. But, back then, some oils met higher standards than others. So there was a clear linkage between my observations and the API rating.

Exaggerating is fine, but that doesnt make much of a point assuming they are trying to deceive anyone, im sure if there was any funny business that someone in the 20 years that display has been around would have figured it out & plastered it all over the internet or in the car world. Its real oil on one side & the same oil treated with lucas on the other. Im pretty sure the stores added the oil themselves, lucas didnt ship them with oil in it, a good friend of mine was a manager at oreillys for 10+ years, hes the type that would call BS on things like that.
Oil alone doesnt have the clinging effect that lucas or other additives have, its diluted to 10% so doesnt effect drain back, just adds a stronger film to parts which helps with dry starts etc as dragncar has explained a few times. If you are a skeptic of it you are free to do so, but that doesnt mean it doesnt do what it says or there is anything deceptive about it.
Not sure what years you are saying oils had lesser specs than others, but if they were certified to meet an API spec they all met that spec, but just like today oils do have different additive packs, each brand formulates their oil a little different, doesnt make any of them inferior as far as API specs are concerned. Ive heard stories of old penzoil causing sludge, maybe that was a certain run or blend 40-50 years ago, but none of that applies today.

I would be willing to bet that contraption that Lucas placed in literally thousands of auto part stores sold millions worth of the stabilizer. You have to admit that was a pure genius idea. I think STP had a TV commercial where you dip a screwdriver in STP then try to hold on to the tip without it slipping out. Does anyone remember that commercial about 50 or so years ago. I can remember doing just that, I remember STP passed the test and I couldn't hold the screwdriver. I was a believer in STP after that. My cousin had a Ford Falcon and his transmission was slipping. I poured in a can of STP into my cousins Falcon's automatic transmission. I don't remember if it helped or not we were kids we had fun that was over 50 years ago.

STP may very well do the same thing as lucas, it is a very sticky oil thickener too, but STP does have some actual zddp anti wear additives, there are VOA's out there on it, it used to have a lot more but still has some and actually says it on the bottle. Either way STP nor lucas stabilizer are snake oils, they do what they say, lucas never claimed to have other additives in it, its just a thickener when needed and has other properties that can help some engines that may need that type of stuff.

If the engine is healthy and the oil is of good quality and correct weight for the engine, most dont need additives, but using a little lucas or stp doesnt hurt anything and can actually help in certain engines.
Alpine & Clarion were a coupe of the better car audio brands, pioneer & kenwood were good too but the higher end stores sold alpine, clarion & a few other brands that werent mainstream.
