When one conveys information, if they include info the person listing to already knows then they insult that person's intelangence. If they begin talking about a subject at a level that requires a background of knoledge that the person listening does not have they loose the attention of that listener because the listener can't follow what they are talking about. Conveying information is not a one size fits all situation.
LSJ conveys accurate info. For some it's redundant and boaring because they knew this. For some it's educational because they had enough of an understanding to follow what he was talking about and learned a few things they did not know. For some it's noise they can not follow because they don't have enough background.
All in all he does a good job of presenting info.
Those who already knew this info have not put out the effort to teach those who did not know or forgot the info, like he did.
Also, some of his YT videos with Total Seal teach detailed info about piston-rings and clearances, bore finish and materials and a few other things. Again, it's about what level is, insulting, educational, or above the listeners head. It's never one size fits All.
He's certainly an entire level above Scotty click-bate.
I have learned a fue things from LSJ, and will continue to watch him.

BTW, this recent video got me thinking about what I put my Honda K24W in my CR-V through last week when I let it idle for a total of 20 hours spread out over 5 times of about 4 hours each, to make the high output alternator power my 2200 W 4400 W peak high reliabality very clean sine wave Meanwell brand 12 V DC to 120 AC inverter, during a 2.5 day power-outage. Certainly a bit more load on the engine than it normally sees at idle. Makes me glad I have PUP 0W - 20 in it, instead of a lesser 0W - 20.
