Why is my Prius using so much oil?
Your Rings Are Choked Up When it breaks down, it forms hardened carbon deposits that live in your piston rings. When piston rings get plugged up with carbon, they cannot scrape the engine oil off the cylinder walls. This, in turn, causes more oil to be left in the combustion chamber and burned off during regular use.
What causes an engine to use excessive oil?
Because of wear, vehicles are more likely to consume engine oil as they age. Common culprits that result in burning oil include worn valve stems, guides and seals, and piston rings, all of which can allow oil to seep into combustion chambers.
How often should you change oil in a Prius?
Recommended Oil Change Intervals for Toyota Vehicles However, as engine technology has advanced and grew more efficient, this is no longer the case. Toyota recommends that customers change the oil in their vehicle, or have it changed for them by a professional every 6 months or 5,000 miles, whichever comes first.
How much oil does a Toyota Prius use?
Understanding anything requires us to know what it is. Oil consumption in our Toyota Prius is when the gasoline engine actually uses the engine oil in large quantities between changes. For example, under normal operating conditions, your engine could consume up to 1/2 quart of oil over 5,000 miles. My 2007 however is using much more than that.
Why does my Toyota Prius burn so much oil?
The chemical will soak into the carbon and you should see it “dry up” meaning that it has softened the carbon to allow it to burn off during normal engine use. In theory, all of this should work and in speaking with other technicians, they have had good results on Prius doing this method.
Is the Toyota Prius the ” before ” car over?
Prius the “before” car has been one for the books for sure. It also is not perfect, and with known issues such as oil consumption this has left some owners wondering if this is the end. My answer answer from a technicians stand point is no, it is not over.
Why are the piston rings on my Prius not working?
The piston rings are there to prevent oil from entering the combustion chamber while also providing the compression needed to run the engine. When deposits get caught in the ring lands (where the piston rings sit on the pistons) this does not allow the rings to seat properly inside the combustion chamber.
