Not intending to start any sort of debate just sharing some very cool tests I've been watching on YouTube.
This guy tests all sorts of things - Harbor Freight tools, oils, epoxys etc etc

I find some of the visual test results very satisfying to see - especially with some of the tool tests - Snap On vs Harbor Freight for instance
This video is SuperTech vs Redline motor oil - he has several others available as well, Amsoil, Mobile 1 etc etc

 

I am a huge Redline fan, I will watch with open mind

 

"Let's find out..." lol
I've subscribed to Project Farm's YouTube channel for years now.
The Amazon oil test and his Seafoam test were very impressive.

 

Thanks for this - The Seafoam test is one I need to watch..........

For something weirdly satisfying - watch this one where these two motors run till they die -
