3. Oil is not something that you can change in your own car unless you're ready to permanently ruin whatever concrete you do it on. Sounds like the author gets their car maintained with an app. ;)
I’ve changed my oil on the side of the road many times. (No garage) If the car is raised enough, you don’t even need a jack. Oil drain pan and some paper towels is all you need beyond basic tools.
If anything - you sound like you get your oil changed with an app...
Thats just not true at all. All that means is that you're slow and forget to move your oil pan from underneath your oil drain to underneath the filter.
Then again I was raised by a single immigrant mom. I was taught to pinch pennies in ways many people cannot relate to.
