My parents came from hot countries, where the smell of uncatalytic-converted exhaust under the oppression of humidity make nostalgia. Countries where far too many people usually carrying far too many infants lash themselves to vehicles that could nominally be called motorcycles. If a 250cc Honda breaking every Federal Vehicle Safety Standard (and some yet to be written) while careening between two larger buses (with not so much blind spots as blind panoramas) could be called a motorcycle.
Car maintenance was not a well-covered subject.
I can still remember my dad showing me that when the oil was low, you just add another quart. It's quite alright, feel free to recoil visibly from the screen.
It wasn't until I had my own car that I learned about things like timing belts and oil changes and all sorts of filters. So now, of course, I get regular oil changes.
There are things that cause aggravation, however. Sitting in the car, having the oil technician explain all sorts of things to you, positively cowing you with technical jargon you only ever hear about every 5000km. And it's always said in such a way as it's assumed you have any idea what fluid they are talking about. "Oh yes, the flambgerge diatcontatenator, of course, that needs to be flushed!". "Why wouldn't the triambulating kraanstenmeter be refiltered with a synthetic proformance lubricant?!".
And it was in a flee from this technical brow-beating that I endeavoured to learn to change my own damn oil.
It's not horribly complicated. You get the type of oil your car needs in sufficent quantities, you get the model of oil filter it needs. You get a car jack to hoist your many thousand pound amalgamation of steel and rubber hoses above your squishy, fairly clueless skull as you wriggle beneath it and try to find which nut, exactly, sets forth a gloopity schlupp of old, dirty oil. I may have devolved in Seussian terminology there and that's mainly fear induced. The filter and oil all make sense to me, marginally. The Hoist Really Heavy Thing Above your Head gave me pause.
It's reassuring, the heft and weight of the entire jack system, with the.... feet.. things... and the wheel stopping things. But something about my complete lack of most vehicular knowledge plus my confusion at society's misplaced trust that I'm certified or in any way trained to hoist an entire car above my head does get me somewhat squirrelly at times.
That whole process I'm constantly looking for the adult to be supervising the activity and find, most worrisome, that it's me.
Contrary to all common sense or laws of causality, I've changed my oil twice so far without any major incident. But, most importantly for me, without anyone asking "If I really think I should let the ammonium dioxicraft stay in the defibrillated counter-position past 3000km".
