Read and be educated

Lucas oil additive - or generally any oil additive for that matter - is bad mojo.
All oil additives on the market today are snake oil. At the very least, they will dilute the additive package that is in the oil as it comes out of the bottle. Yes, oil in the bottle has additives in it. And the additive package (it's a lot more than just one) is carefully engineered to achieve a certain minimum level of performance. But, not all oil manufacturers use the same additives, nor in the same amounts. It's a very carefully engineered balancing act, as some additives will actually react with each other.
So, along comes Joe Lunchbucket who saw the latest T.V. commercial or the nifty new display at AZ. He buys a bottle of the new whiz bang stuff and pours it in. He has NO IDEA what's in it, much less how it will react with what's already there aside from the obvious dilution aspect (which incidentally is what you saw on the linked page from bobistheoilguy).
Some additives can actually cause harm to your engine with what they use. I've seen an analysis on one (no longer on the market that I know of) that had chlorine in it. Incredible shear strength. It would allow a Briggs engine to run forever with an empty crankcase. Don't put it in your engine, though, or you'll get acid formation that is out of this world.
Others use teflon, or PTFE, which is a particulate. What do oil filters remove? The dirtier the filter gets, the more it removes.
Any one that uses any kind of oil additive is asking in a serious way for an expired engine, transmission etc.
