I did everything I believe was right for my ‘17 Theta II 2.4 L GDI engine and it burns more oil than any engine I’ve ever had (close to 3/4to 1 qrt. over a max 4,000 mile OCI). Of course it’s my only GDI engine to date … All my other PFI engines bought new with same good oil change practices never burn a drop of oil . The wife’s ‘07 Sedona with 3.8L PFI Hyundai V6 went over 300,000 miles on up to 5,000 mile OCI’s with M1 5W30 vanilla oil and never burned a drop of oil … That 3.8L was a decent Hyundai engine .
