I'm really liking this bloke Matt's channel. I like his style - blunt honesty with facts and profanity. He's very knowledgeable, will admit his errors and churns out a mass of content. My favourites of late are his rants against "Hard break in" and using waterless coolant for cars (and bikes). Seen this yet? https://www.youtube.com/channel/UChYdD3BgfawTdKlnUJBeOMA/videos
