Dear Patrick,
I have been a Nissan driver my entire life, and I currently love my Nissan Rogue. However, I keep noticing its fuel mileage takes a dip in the winter. Should I be fixing something?

Hi Rhonda,
As if cold, grueling weather wasn’t tough enough, right? We have good and bad news about this discovery. The upside is that you are not crazy! No matter the car, it is likely to experience a 20-25% drop in efficiency during frigid temperatures.
There are several factors that lead to this. Mainly, gas mileage is calculated in a laboratory under ideal driving conditions. While weather testing is standard for a lot of components, MPGs simply isn’t one of them. So, when we put added stress on the motor, like a heater and defroster, that’s the reason you are seeing these numbers.
Now for the not-so-great news: there is not much that can counteract it. Just know that it’s perfectly natural and nothing to be alarmed about. The best solution we can offer is to keep watching the meteorologist’s report in hopes of sunny days ahead!
Let me know if I can tell you more regarding this complex topic.Â
