The new Hyundai / Kia Smart Stream 2.5L GDI engine has been singled out as having loose fitting rings / piston (among other things) in an effort to squeeze out more miles per gallon of gas . This is resulting in oil consumption as oil is getting past the rings and burning off along with scuffed cylinder walls . I believe Hyundai / Kia is not the only 2021 or newer GDI engine to have this concern in an attempt to increase gas milage . Is there another way to meet CAFE's newer standards without resorting to loose fitting rings / piston in newer GDI engines which results in more oil consumption and cylinder wall wear ?
