I have a volvo S60 diesel for 10 months (more than 30.000 Km), and I already have to clean the oxygen sensor once and seems that I have to clean it again.

My question is what can I do to reduce the frequency of these clean ups, since I have to leave the car in the garage for the whole day.

Do I have to replace it ?

Must I change my driving style ?

Must I use a different fuel ?

  • How do you use the car? Does it frequently go on long (45min plus) journeys? Commented Sep 26, 2017 at 12:39
  • @SteveMatthews yes I daily make two highway journeys of 60minutes Commented Sep 27, 2017 at 4:57
