If the engine is losing oil and you can't see it, it's going somewhere. Where it's going is out the exhaust through the combustion process. could be bad rings, but if this just started, it's more likely worn valve guides or a defective PCV valve. Have the engine diagnosed by a mechanic. This might be serious or it might be simple.
