Orange> $30-$80 to do an oil change than spend an hour or more on it at home… Yeshivish people have better things to do.
Do you earn more than $30 after tax? if yes, buy the service. If not, do it yourself. If you are not earning anything, and someone else pays for your learning, ask him if he is willing to pay for your oil change. He would probably ask you whether you are using the car to learn.
