New lakespeed test!!! Havoline 10W-30 Conventional VS Supertech 10W-30 Full Synthetic

The biggest take away I took from this latest video is to look at the bottom of the oil container. Unfortunately I did just that yesterday changing my son’s oil (Pennzoil Euro 5W30), and it did look like there was some stuff there at the bottom of the empty container.

The next jug I shook up BEFORE, and halfway full and MY LORD the color of the oil being poured got very different looking during that second half. And there appeared to be nothing at the bottom of the empty container.

From now on I will be shaking the ever living crap out of oil jugs during oil changes. Add this to my list of overthinking things.
I've noticed this happening with Pennzoil more than any other brand for some reason, but it got me starting to shake the jugs now regardless of brand as well.
 
Thinking of going back to CS even though it’s no longer available at Costco. How long were your OCIs on it?

Short OCIs, 4000 +/- miles. 5K max. I would go by touch, smell & color. If the color was getting too dark, I would change it sooner.

iirc, Costco box was 1-Quart/10-Pack and $22 on sale.
Few years ago, I read on bitog that Chevron is dropping Supreme ... but i still see it at Wal-Mart on the lower shelves next to the Super Tech for $18-19 / 5 qt.

Havoline PRO-DS Full Syn 5W-30 at Wal-Mart is also good. I see the 6qt box on sale once in a while. I had 2 boxes and they are gone. Was busy once and went ~7500 miles before changing the oil and it didn't burn any! I was very impressed. These days, 7500 miles is over my max even with the "EP" oils.
 
Say what you will about Lakespeed, his videos certainly bring activity to the forum lol.

I like LSJ, but agree many of his videos are too long and his topics drift as he narrates. But I still enjoy the content as not many people are posting good oil related content on youtube with ACTUAL testing, aside from some VOA/UOA they sent to blackstone. Youtube is for entertainment, and I find him entertaining most of the time, especially his videos about his Dad's racing history.
 
IMO, project farm never, ever presents himself as an "expert" of any sort. He does just-for-kicks real world type tests on things, then gives his opinion and tells the viewer to draw your own conclusion. Conversly, Scotty and LSJ present themselves as authorities on auto and lube matters. No, I rarely watch project farm, but the other two? None.
 
This video wasn’t just about engine oil, it also covered ring design and cylinder wall finish.
For those that have followed those topics including crankshaft journal finish and bearing material for decades will get more out of the presentation than most.
LSJr includes back stories to explain the results of the experiment and why his results may differ from other engines.
 
No self-respecting lab tech or QAE would endorse his methodology or conclusions.

Sample sizes are simply too small; it’s anecdotal “science” meant for YT. And that’s just the tip of the iceberg …

I do not doubt his credentials. But those credentials clearly don’t include any meaningful form of understanding DOE protocol.

If he attempted to submit these “test results” for SAE review he’d be laughed at all the way back to his niche on YT.
Like @Pablo, I also spent most of my career in Quality, supervising test labs, and as a Quality Engineer. It drives me nuts when people reach conclusions based upon very small sample sizes, when differences that they are talking about, are small enough to be just noise - nothing more than normal variation.

I believe LSJ knows his business. But he also seems to be willing to say a lot of things, rather boldly I might add, just for sensational Youtube traffic. It is disappointing.

If you don't watch the motor oil geek, then how do you know he isn't teaching someone how to draw their own conclusions?

True, but the window of opportunity to retrieve any data from a new engine is very short. In contrast, an automotive engine fully broken in with several hundred hours will show almost zero wear metals in a few hour dyno run regardless of engine oil.
LSJr has to get the camshaft broken in with a high zddp engine oil, drain that oil because it negatively affects power, then quickly test a few different engine oils to see what the rings like.
Why did he prefill the oil filters? To find the answer you must watch one of his previous videos, if you haven’t already.

Carl Banks is another automotive content provider. His videos are longer than necessary because he gives us the back story as he goes along.
