Determining the Proper Oil for Your Engine - Email from Lake Speed Jr

[Jetronic]

I call em like I see em.

If LSJR produces a vid with great info I praise it and post it, if it’s misleading or not sound I call it out.

If LSJR has something to say about oil, I'll listen. I might not agree, but I'll make up my own mind. If a gazillion other youtubers have something to say, I'm likely not interested.

The Cu always trends down so I don't think it's mechanical wear but more of a chemical reaction. There are many that have well over 150k on HEMIs that used RL and never had a problem.

Yes, it's definitely chemical. The assumption was that it was from the oil cooler, but it could also be from a copper-based sealant or some other copper-containing component or compound.

LSJr's approach to wear metal accumulations are, well, misinformed at the very least.
He is, IMO, making good money off giving average-at-best advice.
He makes three very important mistakes in his approach:
- he combines wear metals to get a "total" per 1k miles; as if those metals can be lumped together to understand wear traits ... (SMH)
- he completely ignores the topics of macro and micro statistical analysis
- he completely ignores the topics of understanding process variation

UOAs are great tools, but they have to be understood as to what they are and are not good at. And more importantly, once you have the data, how to accurately and properly process that information.

A retired cop knows more about motor oil than LSjr????

A lot of Red Line samples show lead aswell. It's just one of thoise things to be aware off, or just don't do an analysis.

Exactly. His latest video on surface texture and GM's recent issues is a great piece. I am sure there are "experts" here on this forum that will find something wrong with his analysis but it makes a lot of sense to my small mind.

Retired cop vs BA in advertising. It could go either way.

It's just OK

That was my world for 30+ years. Pretty light.

Did he actually mention the actual SB and IS condition of the GM cranks? I may have missed that.

Lake has to make the information understandable for us newbies to oil and it's many layers of complexity. I appreciate his drumming down the process so I can understand these layers. If somehow that makes me enlightened, so be it. I just hate to see people spreading knowledge by people claiming even greater knowledge. Ironic, actually. I hate it when people play "see, I'm smarter.". I do agree criticism is part of good science but I see a lot of piling on, similar to my experiences in grade school. Live and let live. Take what one finds informative and let the rest go. Everyone is in a different place of understanding on every topic.

Do you mean you appreciate his "dumbing" down the process so you can understand it?

Ad hominen argument? Is that the best you can do to refute the retired cop positions?

No, you didn't miss it. He only referenced the GM recall and possible issue with the crank finish long enough to use it as clickbait in his title.

I thought the video was interesting. The PhD did most of the talking (assuming he has a PhD since he was referred to as "doctor". It could just be his nickname).
