Whining noise above 50mph, no power when pressing gas pedal to the floor

What is your question?

I have an 08 kia rondo roughly 104k miles, driven very little as I work from home. I was driving on the freeway at 75mph and noticed a whining noise only when holding my speed when pressing the gas or taking my foot off the noise stops. Now there's absolutely no oomph while stopping the acceltor to get onto the freeway or other situations where you need your car to accelerate quickly. It also seems to be burning ALOT of oil and the check engine light is also now on. There are ZERO signs of any fluid leaks.

What makes this problem better or worse?

Everything makes it worse
