when I was growing up, it was common for 10 year old cars to be so worn out smoking badly, and oil pressures nonexistent, the idiot lights all running on oil... as the roller cam cars and better oil formulations came out, older and older cars came in for service. (it probably helped that cars went from 2K new to 30K new...)
oil changes are WAAAAAAAY cheaper than car payments.
