Three problems related to engine burning oil have been reported for the 2008 Chevrolet Silverado. The most recently reported issues are listed below.
Excessive oil consumption (1 us quart/1,000 miles).
Oil consumption 3 quarts between oil changes - no leaks no black smoke - and now I'm hearing a rattle in the engine.
1 to 2 months after purchase the oil was completely out on my truck. They have attempted to fix the oil consumption is 3 to 4 times. Now they are wanting to replace the piston that they have already ordered not knowing what kind of damage has been done.
