Services > Emissions


Some states require regular safety inspections and/or emissions inspections on cars and trucks. At Portland Automotive, we are well-equipped and trained to perform these inspections. Our technicians can also perform multi-point inspections on your vehicles as needed.

What is an emissions test?

Emissions testing or Smog testing is used in many areas of the country to improve air quality. But even if your community is not affected, you still need to know about emissions testing and smog checks because problems that often cause emission failures can also cause a variety of drivability and performance complaints.

Mandatory emissions testing has become a fact of life in many areas as a means of identifying vehicles that are "gross polluters" so they can be fixed.
