A short answer to this question is yes. Motor oil can only last for a certain period of time. For this reason, oil goes bad with time just by sitting in the engine. Over time, it becomes less viscous thus less efficient in maintaining proper lubrication between moving components.
How long does oil last if you dont drive?
Its a tough question: How often does the oil have to be changed when the car will not be driven for an extended period of time? The answer may surprise you: the typical lifespan of unused motor vehicle oil is about five years.
What happens to engine oil if car is not driven?
Your oil may be fine, but its the moisture in your engine thats the real enemy. If you dont run your car for very long very often, the engine wont get hot enough to burn off this moisture, and your oil wont be as effective at lubricating your engine, eventually leading to shorter engine life.
How often should you change oil if car is not driven?
Its not just about miles: If you dont drive your car a lot, your oil still needs to be kept fresh. Even if you drive fewer miles each year than your automaker suggests changing the oil (say, 6,000 miles, with suggested oil-change intervals at 7,500 miles), you should still be getting that oil changed twice a year.
Can a car lose oil without a leak?
Even without blue smoke or a burning oil smell, you could have a car burning oil but not leaking. Oil consumption is a normal part of engine operation, with normal oil consumption averaging up to a quart per 2,000 miles. It can leave your crankcase low on oil.
Why am I losing oil but no leaks?
The engine must maintain a certain amount of oil to run efficiently and prevent engine destruction. If your car is losing oil but no leak or smoke, the problem is usually related to an internal oil leak that you dont notice or important faulty components in your engine.
What are the signs of worn piston rings?
When drivers notice excessive oil consumption, white or gray exhaust smoke, poor acceleration, and/or overall loss of power or poor engine performance, they may be seeing signs of worn piston rings.
