Engine Oil Consumption


Troubleshooting Engine Oil Consumption

Is your oil level low between oil changes? If your car’s engine is operating as it should, there will be no need to add oil. Unfortunately older engines rarely enjoy this luxury. As the engine wears, oil makes its escape. A little oil added now and then is nothing to worry about, but if you’re adding a quart or more between oil changes, you may have a fixable problem in there. Your engine may be burning oil thanks to worn piston rings. Your engine could also be leaking oil thanks to a bad gasket or cracked part. Or you could be losing oil through the head gasket into the cooling system. This can be an expensive repair.
