I know Car wizard makes good videos I would look into his advice Car wizard is more calm than Scotty;)

I like Car Wizard and generally agree with his views/recommendations. But like everything I life, take with some grain of salt, do research, ask here on this awesome Forum, and learn as much as you can in order to be informed.  I sometimes even disagree with Scotty on some issues (it’s rare though). 

I recommend watching a bunch of mechanics on the same topic to look for best practices and consensus. Many a good mechanics. But many are horrible too. 

sometimes the pro mechanic makes good videos  sometimes the amateur is more helpful  Watch a bunch on the same topic.

Car Wizard is pretty good, but also is human and has made mistakes (like with Hoovies SLS). 

Scotty is old school. And I don’t mean that with disrespect. He has a bunch of built up knowledge over the years. 

It's amazing what a $20.00 magic wand will do. You have to remember that the $20.00 magic wand is an entry level wand with limited powers. The best magic wands are several thousands of dollars and are used by professional mechanics and come with a limited life time warrantee. They work like magic.

I'll bet you if you ask Scotty very politely, he will do a video showing himself using his magic wand to repair the toughest car problems.

I have been watching a variety of YouTube mechanics lately. Can I really fix a $1000 Jaguar XK8 for $20 and have a dependable daily driver?
