2011 4.6 with 130k. Try cleaning your pcv valve, I was burning about a quart every 500 miles. Lucky for me, I’m getting better performance, better mpg, and zero oil burning for thousands of miles since cleaning. I would start there before assuming the pistons need new rings. I thought I needed a rebuild until I took 15 minutes to complete this easy service. also, put some 91 octane in it to clean those valves! Your engine is port injected! More importantly, research the forums better! This forum is a treasure trove of genesis Knowledge!I have a 2010 4.6L with 158,000 but.... after 150,000 it’s burning almost quart of oil for 1000 miles wtf ???
101156, 2012 5.0I am in the Ford Expedition forum. Someone did a roll call for how much mileage. A few were over 400k, several more in 300k range, and bunches in the high 100k or in the 200k range. Was great to read some of the stories and info. I bet there are some high 100k Genny floating around. And others with high mileage compared to the age. Let's hear about all mileage..
