The car uses about three quarts of oil every 7,000 miles. No one could find anything wrong, so my local garage told me to just add oil. Is there a more cost-effective solution?
Q. My 2013 Buick Regal with 80,000 miles is burning oil fast. The car uses about three quarts of oil every 7,000 miles. I took it to the dealership and to my local repair shop, but no one could find anything wrong. My local garage told me to just add oil, which I have been doing. Is there a more cost-effective solution?
A. Adding oil is the cheapest alternative. The problem is most likely that the pistons and rings need to be replaced. This was fairly common on many General Motors models between 2010 and 2013. GM issued a technical service bulletin titled excessive oil consumption. Since your car is outside of the warranty, it would be unlikely that GM would do anything to help with the cost of repairs, but it couldn’t hurt to ask Buick’s customer service representatives to explain the problem.
