Forte

  • CVT transmission
  • 35,000 miles

Help, I’m looking for an answer/cause. I have a 2020 Kia Forte.

For 2 years, I had all my oil changes and service done at the same dealership with no changes to the car mileage. The last oil change I had done with them, I brought it in with the mileage reading 42mpg and left with it dropping immediately from 42 to about 32mpg on the way home.

When bringing it back with my complaint, they denied anything different was done and it was the oil that did it. Strange is that it was the same oil I always had them use. I questioned that if this were the case, it would have changed along time ago.

It’s been more than a year and the 42mpg has never returned, even after taking it to a different dealer for oil changes. Something more than just an oil change was done to the car. Coincidence is that for some reason the oil change took a lot longer than normal that day. I was happy that my car was getting much better mileage than normal. Would even get 45-46 sometimes on the freeway.

Hoping that after the mechanic saw this he didn’t exchange a part thinking that I wouldn’t notice.

Anyone have an idea on what the mechanic might have done or replaced to make such a drastic mileage difference. Thanks ahead of time.
