(the "didn't fill" from above are all from AFTER the fix)
I did this a long time ago but I only posted it now because I wanted to make sure the issue is gone. And it is!
I finally found the culprit that's been filling up my damn air filter, making the car run like shite and using oil like diddy.
It's this at #4, the oil separator.
This car hasn't had an oil change in a LONG time before I got it, gunked up the oil separator, clogged it, and the oil started going up instead of back down into the engine. Swapped, and you can see in the photo above how it was immediately fixed after. It's actually pretty easy to remove, it just takes time to take off the airbox first, or at least that's my mechanic told me. How he didn't figure it out when I asked why I had oil in my airbox is beyond me, but whatever.
The whole job is almost as cheap as the oil I had to keep adding.
If you have this issue, you will see oil coming out from this tube that goes in the airbox at #36.
You didn't ask for an auto troubleshooting tip? Well too bad!!!!
Mine's a Golf 4 1.4 petrol AXP by the way. Though, I think many cars have similar things.
If you know a community that could use this info lmk, I'm still trying to figure out lemmy.
I don't see anywhere in that video where he says that. Do you know about what time in the video he says it? Your linked video doesn't have him testing or talking about Valvoline at all, and he's testing on new engines.
Here are some of his videos he made on restore and protect that are pretty much the opposite of what you are saying. Also, many of his videos on restore and protect may have been after your referenced video, so he may have not even known about it when your linked video was made.

Interesting, thanks! I may not have gotten a clear message from what I watched.
