Motor oil demystified

Your closing statement went through my mind during the working engine transparencies.

I love videos featuring Brian Cooley. I have been watching videos featuring him since 2006 when it was a flash based web applet called CNET TV. I wish he would still do car review videos...I miss those. He has an interesting take on cars.

I wish Cooley had his own channel, this way I can set it to notify me of new episodes. I don’t like every posted on Roadshow

Great video! As he said, go by the owners manual for the correct oil, period.

Good to have you back, Cooley. Regards from Sao Paulo, Brazil.

Bravo my friend. As a professional auto technician you hit all the topics with facts. I will certainly point my customers to this video when they ask about engine oil.

The thickest crankcase oil I've ever seen was for a vintage British motorbike which was using 40w-70. My Suzuki car requires 0w-20. What a change, from pretty much diff oil to water.

[dbrandon]

It’s so sad that we still need videos like this in 2021...

[ashishpatel]

Actually informative unlike other videos on oil.
