Sandro is like a teacher who changes your grade from F to A+ if you give him a legitimate reason. already fan of him

[lumare]

Sandro's cheeky little "that's how you get gas from your neighbors" killed me :D love that guy

[swoosho]

Glad to see Sandro being a regular now, he's such a funny guy with a good vibe

[Edsel]

Sandro is a man of many talents. He's a mechanic and a comedian, and judging from his canine teeth, a vampire.

Sandro talking about ruining your pedicure while pulling an oil plug just shows that he's such an amazing mechanic that he is out here changing oil with his feet, incredible!

[ゲリン]

I just love the humbleness in Sandro's eyes... Yet he is very cool. I just automatically feel compelled to respect every word this man says.

[AyasiTV]

lmao when he said "and thats how you steal gas from your neighbour" i died the fact that the the more you know card popped up made it 100x better hahaha

The head/door opener thing works because the amount and shape of water in your head is roughly the right amount to act as an amplifier for the radio signal from the key fob. You can do the exact same thing with a gallon jug of water (or watery solution like milk, washer fluid, detergent, etc). Your head is essentially acting as an antenna for the signal.

With the tire regrooving, you can see that they filled the newish tire's tread with something and are simply scraping it out.

For the oil one it would work great in desert places, I worked in a tire shop in phoenix and we had to do hot changes. One of the guys at the shop had a 3rd degree burn going from his hand all down his arm from doing them.

Sandro is that cool af uncle you’re always happy to kick it with and he’s always got the best stories and advice. Just has that good vibe

[boneless]

The thing with the cat guard setup is that it doesnt have to make it impossible to get, it just has to make it less appealing than finding another car

[ttsuyaguy]

I really like that you didn't just compile the stupidest things on the internet to flex on. The mixture of good ideas and bad ideas, the fact that some of the ideas are _almost_ good, all adds to your credibility and makes that the whole video more interesting.

I think the reason for the zip tie on the cap for the oil pan was to help stop accidentally dropping it in the pan

[saewoody]

I’ve used the double wrench, but never seen the triple!
It’s like I always say: you can always get the job done with the right tool; but you can also always get the job done with enough of the wrong tools!

[beeeennnnnnn]

making this channel was a great decision guys!

12:30 Reminds me of a funny time where a friend of mine wanted to use his remote start to warm his car up but he was too far away to get it to work. We both happened to be sousaphone players (Tuba that wraps around you), so he looked up at the bell on his, touched the fob to the brass and started his car from a literal football field away.

[personwhohasayoutubechannel]

I love how everyone is talking about mechanic stuff and Sandro is still thinking about theft lmfao

[spamuel]

13:00 Kyle Hill actually made a video on that specific topic; it actually works because the wavelength of the radio waves used in those keyfobs for your car are a similar ratio to the size of a human head, so providing a slight barrier that lines up with the wavelength amplifies the signal. Or something, it's been a while since I saw that one.

The love for Sandro is wild. Dude is awesome.
