I had the oil changed on my Ford Focus last week and they used 10W/40 instead of 5W/30 so I went back a day later and they replaced it with the 5W/30.
They took only about half an hour to drain and refill the new oil. Do you think that they could have done this job in only half an hour or am I being too paranoid ?
Thanks !
