Your diesel emissions system is a complex network of parts that monitors and controls the amount of diesel exhaust smoke and emissions released into the air. These systems help keep your engine operating efficiently and reduce the number of harmful pollutants that are released into the environment. Regular maintenance of your diesel emissions system is essential to ensure that your vehicle runs at its best, and we recommend that you come to John's Automotive Care for all your diesel emission service needs.

Diesel emissions systems can be complicated, but they are necessary to reduce nitrogen oxide and other harmful emissions. When your emissions system is working correctly, you don't have to worry about failures or visible smoke from your engine harming the environment. However, if you neglect your emissions system, you could damage your engine's performance and contribute to pollution.

Our expert auto mechanic technicians at John's Automotive Care can perform regular emissions system maintenance checks during your routine service interval to ensure that your system is working correctly. We recommend emissions system maintenance at 15,000-mile intervals or every 30 months, whichever comes first, to ensure optimal performance and prevent costly auto repairs down the line.

Check out this review of one our many happy customers:

"When I replaced tires recently, I discovered very uneven wear, requiring a wheel alignment. Although I had never used John's Automotive before, they had excellent references on Yelp and other sites so I called and made an appointment. Their service was friendly and professional and my car was ready for pick up a few hours later. The bill was exactly what they said it would be and it was a very reasonable amount. I will definitely come back the next time either one if my cars needs service!"
