CTRebbe, do you actually disagree with me? It sounds like you are speculating about my “mindset”. You didn’t see my advice regarding unscrupulous mechanics? And honest mechanics are entitled to their parnassah just as much as you and me.
I’d rather see someone spend epes $30-$80 to do an oil change than spend an hour or more on it at home, not to mention properly disposing of the oil. If someone wants to learn how to do these things correctly, with the proper tools and practices, of course they can. I’ve done a lot of these things myself, including batteries, belts, hoses, lights, sound systems, exhausts, valve covers, thermostats and gaskets.
And what Gadolhatorah said is also absolutely right. Even changing some bulbs used to be easy and now they can be a major balagan. Yeshivish people have better things to do. I’d rather spend my time on my family, Yiddishkeit and my day job.
