That's a HIGH burn rate that I would not want to deal with. My son's 2009 Vibe GT, 2.4L w/automatic, when we initially purchased it back in 2011, burned a quart every 1500 miles at just 35000 miles I immediately switched it over to FULL synthetic Mobil1 and the burn rate slowly decreased to the point now where it may burn a quart every 2000-2500 miles. Car is presently at 150k miles. I'm convinced that the full synthetic played a part in extending the life of his engine!Transylvania wrote: ↑Wed Sep 15, 2021 7:34 am I use semi-synthetic oil and change it every 5,000 miles. Using Toyota oil filter that I purchase on Amazon. Have 235k on a 2010 2.4L engine that burns a quart of oil every 1,000 mile. Other than that, no issues at all.
