Has anyone else had this issue? Acura says it's normal for a new MDX to burn up to 1QT every 1,000 miles. My brand new 2008 MDX has 13K miles on it and 3 times I've taken it in when the oil either doesn't register on the stick or it reads at the lower hash mark. All 3 times, the dealer fills it up, confirms oil reading and about 1,900 miles later, the oil level is on the lower hash mark or not even registering on the stick. The dealer has done compression tests, bore scoping and oil residue search in exhaust and catalitic converter with no luck finding evidence of burning oil. No oil in my driveway or garage either ;-) Acura says this is normal and won't do anything about it. Advice anyone?
