If your engine has the noticable pistonslap noise when cold start up . That could account for the consumpsion . My T/A with LS1 has it in the cold months and uses a quart in a month (800-900miles). But in the summer I don't use any noticable amount between changes . Just a thought . Rob

All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.



Excessive oil consumption, not due to leaks, is the use of 1 L (1 qt) or more of engine oil within 3 200 kilometers (2,000 miles).

I would like to add that if you are towing, that will up the oil usage a little too.
