All of us in Chicago know we have to get the oil changed in our vehicles periodically. That's just part of good vehicle care. But when Tuffy Chicago (Diversey Pkwy) technicians change your oil, they also usually inspect your air filter. That's why they sometimes let you know that your air filter needs to be changed before releasing your vehicle.
Don't just chock this up to trying to sell you something else. Chicago area drivers really do need to change their air filter when it gets dirty. You can check your owner's manual to see how often your air filter should need to be changed, but remember, if you live in an area in Illinois with poor air quality, or if you drive a lot or drive under harsh conditions in the Chicago area, you may need to change that filter more often than is recommended.
Changing an air filter isn't guesswork. If a filter's dirty, it needs to be replaced. Air filters aren't very expensive at Tuffy Chicago (Diversey Pkwy). But the problems they cause if Chicago auto owners don't change them can get to be.
