After GM upgraded the 2.4 Ecotec to Direct Injection the piston rings were wearing out 3 to 4 times faster than expected. Oil consumption started at 20k miles and steadily increased to 1qt/1500 miles at 42k. From what I’ve read my Equinox was a textbook case. Both the 2.4 and 3.6 6 cyl had problems with timing chain stretching after the DI consumption. The thread I started a ways back has more detail, it’s rather long.
