AAQ,
You say that if people are making less than $60 an hour, they should do their own oil changes. Especially if they are learning in kollel. Because an oil change costs $60.
For someone who “always ask questions” you did consider some very simple ones that show the fallacy of your comment.
1) How much does the oil cost, (Actually, about $23 for 5 quarts now)
2) How much does the oil filter costs (Cheapest is $4.50, better are about 8.50)
3) How much do the tools for doing an oil and filter change cost (considering that a person would typically need maybe 2-3 oil changes a year)(Wrench, funnels, oil filter wrench, oil drip pan)
4) Where I live, the oil change places include a car wash in the price, that is worth a few dollars
5) What about the hassle of disposing the used oil and filter
6) There is a cost to purchasing the other fluids that get topped off at an oil change
7)The amortized cost of clothing that you can wear when doing an oil change. You don’t expect a kollel person to do so in his white shirt and dress pants. And more casual clothing is not suited for that either. Perhaps the clothing you are used to wearing might be more suited.
By the time you add that up, the savings for doing an oil change by one’s self really is very small if at all and likely does not exist.
Additionally, it often takes significantly more time to do an oil change at home (including the associated clean up) that going to a quick change place. This is time that many Yungeleit do not have. They are busy shopping, or with kids during bein hasedorim and evening hours as well. Neither do they have off on Sundays. And many people do not have a place they can just do an oil change. It is not wise to do so on a public street, and not all driveways are suited for that as well. And if oil spills during the change on the drive way, its a huge hassle.
I have a relative who is a regular yeshivish person. He did his own oil changes. But he was driving between 1,500 and 2,000 miles a week for his job. For him it was a savings. But most people, it costs more do a change your self, if you add up the actual costs. (And if you have an issue with car, you may have an issue proving oil changes done your self, but if you go to the same place you can get a history of oil changes, to protect your claims, but you go buy the extended warranties we all get calls about)
