And then there is Redline Oil's take on it all...

Agree with his 0W 40/50 point for he Beemer in those cold conditions.

No good imo.

There should be a way to affix a rating to online videos.

This way people could save time avoiding trash exercises like this one.

This guy is simply in love with his own voice.

On my Gen Coupe forum there is /was a guy very knowledgeable and he went to great extremes to video the dismantling and explaining the various items he talked about. Unfortunately most of the 'action' could have been edited out and distilled to make a good video. But you have to sit through a half hour of ramblings to get the gist of the matter. I refuse to watch them.....

I did not find as much fault with his video as the posters above. I did find it interesting that his track days with the 0W-20 oil did not cause a significant increase in wear metals in his UOA results.

I live 3 miles from the track (PBIR, formerly Moroso) and during the hot Florida race days, "some" engines have catastrophic trouble with the uber-thin oils. Other setups gain more top speed with the thin oils. It's no secret, but back in the 1980's, Bill Elliot's racecar was able to top 200 and reach 205 MPH at Daytona with just the change from thick oils to thin synthetic.

That same methodology works today, with certain Nascar engines using 0W-10 oils during cold temp races. Leading to over 200 MPH.

The guy in the video said he spent thousands of dollars on engine oils and oil analysis. Give us that data, not something speaking about the temperature ranges and viscosity.

I'm not sure I understand the part about the oil pressure being catastrophically low with a 0w20 in a supercharged/tracked BRZ,FRS,GT86. He did oil analysis and the results returned good. Doesn't that mean the oil protected the engine just fine?

NOPE! UOA results are just a tool. I believe UOA is best used to monitor trends, not to diagnose an acute problem.

I operate a fleet of 8 aircraft, including a really nice Eurocopter EC135. We perform UOA tests every year on the engines and the helicopter transmission. Never ANY significant iron, ranging from 3 to 5 ppm every year for the last decade (limit is 150ppm) . This past year, there was an AD (FAA requirement) to disassemble a portion of the transmission to look for excess wear. We found that excessive wear, severe enough gear damage to catch a fingernail on, and replaced the transmission.

Conclusion: UOA will not find many types of internal failures and they absolutely will not find larger metal "chunks".

Note: I also tried Mobil 1, AFE 0W-20 in my turbocharged Miata years ago. That single oil change resulted in an engine overhaul. The UOA did show excessive lead but did not show high aluminum. But by that time, it was obvious to anyone listening to the engine within 30 feet of the car, the engine had internal damage. The bearings were mildly damaged, the crank was OK, the pistons (aluminum) were absolutely destroyed. It seems the thin oil, coupled with the Florida heat, was unable to handle the bearing loads of the connecting rods and the piston skirt thrust loads. The UOA DID NOT indicate piston damage.

I liked it for the Weights/Pressures and knew that the "other" stuff he mentioned wasn't accurate.

Should look up CATERHAM's Oil Pressure/HTHS tests...it's quite good.

The inferences drawns aren't, but the base work is very good.
