Is it true that the allowable oil consumption for a chevy/gm motor is
1 quart per 1000 miles? It used to be 1quart per 2000 miles. Just You would have to adding 3 quarts (at the very minimum) between oil changes before it would become a warranty issue. Perhaps some exec figures that gm will be out of the internal combustion engine business soon, so why not reduce the standards, and make more motors, faster.What are the standards for the other manufacturers?
