So my mom drives a 2004 Yukon XL with the 5.3 of course.
Its completely stock, never towed really anything heavy.
Never had a strain put on it.
Never been abused, just drives 100 miles a day to and from work.
She has around 190,xxx miles on it.
Heres the problem we are having.
Over the last 6 months or so it started burning oil like crazy.
No check oil level light, no low oil pressure, everything seems normal.
One day it started smoking upon start up so i checked the oil, didnt touch the dip stick, I had to add 5 quarts of oil.
And this is repetitive, today is about the third or forth time we have had to add about 5 quarts.
I just dont understand, no smoke, no oil spots, no low pressure, no check oil level, then one day itll start to smoke and you have to add oil.
Anyone have any ideas?
