Hey Scotty,

I have 2017 Hyundai Sonata limited 2.4L with 54,000 miles and it's almost feels like f-150 when comes to gas rating. What should I do?

so you read both articles (Why am I getting poor fuel economy? and how do I improve it?)
You watched all the videos ... followed all the advice?

Yeah, it also the same thing with my Nissan Altima with the same rating only 20mpg

That’s relatively normal numbers. Do you drive with a lead foot?

No, I drive gently with it

Have you hooked up a scan tool and looked at the fuel trims? Also, you said this happened after changing knock sensor - did you double check around that area and make sure you didn’t accidentally displace something? Makes me a little suspicious that it happened right after you changed the sensor. Then again it could be a coincidence but check around that area again very closely.
