I had a 2015 Equinox with a 2.4 ltr engine. It was a billygoat. Nothing climbed the hill better than that. No 4wd or awd did better. That engine did have a part throttle drone to it when climbing the hill. I tried QSUD, and Mobil 1, but Magnatec got rid of it. I'm a big Magnatec fan. Very smooth in some engines. I only had that car for 20,000 miles, but it never used any oil.
