Excessive oil consumption, piston and piston rings. Burning 3-4 quarts of oil every 2000 or less miles. After checking I find out this is not covered under warranty because it was not make at a specific plant. I have approximately 95,550 miles. I thought Buicks were good cars and stood behind their product. This is quiet expensive, can you help? the oil light doesn't even come on when it got that low. It started acting funny and when checked, low oil, no . I have kept my vehicle very well maintained. The first time it happened around 10/16/17 and after looked at again 1/8/18 drips or leaks.
