excessive oil consumption
my 2013 Silverado is consuming oil excessively. It was down 2 qts over 1600 miles. It is still under warranty and the dealer wants to tear the engine down to see whats going on. they sad if they don't find a part that's defective then I would have to pay to put it back together. It has 74k miles. So my question is it worth it to do this or should I trade it in.
