Our cars aren't alive, but wear and tear takes its toll on our cars' engines and this tends to start becoming acute at around 75,000 miles. There was a time when 75,000 miles meant that a car was about three-quarters of the way to the junkyard, but 200,000 is the new 100,000 miles for cars. That makes it all the more critical to begin giving engines special care at 75,000 miles because they are going to need it to help them go that remaining 125,000 miles.
