I recently noticed that my Audi A5's fuel efficiency has been decreasing. I regularly maintain my car and keep up with recommended services, so I'm not sure what could be causing this issue. Can someone provide some insight into potential causes and how to improve my car's fuel efficiency?
ReplyHi Sarah, I would suggest checking your tire pressure and air filter. Low tire pressure and a dirty air filter can both greatly impact fuel efficiency. Also, make sure to avoid idling for long periods of time and accelerate slowly.
Hello Sarah, another possible reason for decreased fuel efficiency could be a faulty oxygen sensor. I had a similar issue with my car and once I got the sensor replaced, my fuel efficiency improved significantly.
