I know how to fix/do a few things actually (on a car)-
Disc Brakes- Drum Brakes are my next challenge... bluh...
Changing Oil- Way easier then you think
Change a car battery
Refill Oil
Refill Brake fluid
Edit- Also forgot to say that I know how to change spark plugs... I have a few friends that don't even know what spark plugs are... really?
I thought all of this was super easy, but come to find out some people I have run into don't even know how to refill their oil... Which is very sad and stupid if they run into a tight situation.
What are different things you find easy to fix that others might not think are easy? I might learn a thing or two From your responses.
