Maybe I “cured” him, or…maybe not.
Consider the fact that he went 3 years w/o changing the oil in his Scion, despite my reminders a couple of times per year that he needed to do it! He finally had the oil changed about a month ago, but I had to browbeat him excessively in order for him to actually take that step.
For 3 years, I kept hearing the same nonsense, namely, “The oil looks clean, and they don’t specify an oil change until you reach 5 k miles.” (He uses his car only for short-trip local driving, and only accumulated ~3k miles in 3 years. You and I know that this is the absolute worst thing that you can do to an engine, but he persisted with his denial routine.)
I had been stressing the either/or odometer mileage/elapsed time factor for three years, but until I became absolutely brutal with him, he didn’t acknowledge the existence of the elapsed time factor.
I have come to the conclusion that he is simply lazy, and–according to him–the psychologist who he went to for counseling and analysis told him the same thing. He admits that, if he could just lie on his couch–all day/every day–and do nothing except watch movies and porn, he would be very happy.
