Toyota owners with models such as Camry, Corolla, Matrix, Rav4, Solara, Scion xB and tC equipped with the four-cylinder 2AZ-FE engine may experience excessive oil consumption.

If your Toyota has excessive oil consumption the engine performance may be severely diminished. As oil is burned at a high rate, the engine may need oil every couple of weeks.

If you don't check the engine oil regularly, the oil may have diminished to almost nothing by the time the maintenance interval arrived (typically at 5,000 miles for many of the vehicles affected).

Symptoms

 Toyota Excessive Engine Oil Consumption oil level low

Common symptoms include:

  • Oil level low in 1000 miles
  • Oil light coming on
  • Engine noise
  • Engine burns  oil
  • You have to add oil every month.
  • Oil pressure light comes before the maintenance schedule. 

Pay close attention to the oil light. If it comes on before the oil due date, add engine oil immediately.

For example, if you normally have your oil changed every 3,000 miles, the oil pressure light comes on after 1000 miles. Add engine oil and get your car diagnosed as soon as possible.

Cause

Affected Toyota Models due to piston rings

The service bulletin indicates that the cause of excessive oil consumption was defective piston rings not providing the appropriate seal.

In the notice, Toyota instructs technicians to replace the piston assembly which will fix the problem of the engine burning too much oil.

Piston rings that function normally work with oil to seal combustion gasses off from the bottom half of the engine. There is another set of piston rings below it that helps to wipe excess oil from the cylinder walls.

Toyota issued a technical service bulletin to all of its dealerships. Toyota acknowledged the problem of excessive oil consumption in some of their vehicles produced between 2006-2011. The bulletin lists the specific engine types and vehicles affected. The defect affects mainly the 2AZ-FE engine.

A technical service bulletin is not a recall. Instead, it is a set of instructions that are written for technicians at Toyota service departments that outlines repair procedures and warranty coverage, if any.

According to this notice, customers were covered under Toyota's Powertrain Warranty - which lasts for five years/60,000 miles, whichever comes first.

However, they are only covered for repairs under this warranty if they can pass a qualifying test. In a healthy engine, the oil circulates throughout the moving parts and helps to lubricate and cool all of the parts within it.

Very little oil is burned in this process because the oil is reused over and over until it needs to be changed after a certain mileage. The amount of mileage will vary depending on the vehicle, oil type and how new it is.

Depending on the oil type and filter used some cars can go 10,000 miles or more before needing an oil change. With conventional oil, you need to perform oil change every 3,000 miles.

Test Procedure

Test Procedure

You will need to take your Toyota to your dealer and have them check for excessive oil consumption. A Toyota mechanic checks the oil level of the vehicle marks the dipstick indicator, seats it and then tells the customer to drive for 1,200 miles, and return to the dealership at that time.

When they return, only those who are a quart low on oil after driving for 1,200 miles will have their vehicles repaired under the warranty terms. Those who do not meet those requirements are forced to pay for the repairs out of pocket.

Toyota engine oil consumption bulletin is different than a recall, which requires vehicle manufacturers to notify all owners of the problem and cover the cost of repairs. A technical service bulletin, which is what was issued in this case, is essentially an updated repair guide for the service departments of dealerships on how to repair vehicles that are affected by this problem and are still within warranty specifications.

Is There A Recall? 

Because excessive oil consumption is not considered a safety defect, a recall was not issued. Recalls are only issued when safety defects appear.

Things like faulty brakes, steering components malfunctioning, airbags that deploy when they're not supposed to, etc. are considered safety defects. What to do?

Unfortunately for many Toyota owners, the problem of excessive oil consumption did not begin until after the powertrain warranty had expired.

Many customers were forced to pay for the repairs out of pocket or continually top off their engines with a quart of oil in order for it to function properly.

Toyota has said that they have sent letters to customers affected by this problem, beginning in December 2014.

Customers can check to see if their vehicle qualifies at this link https://www.toyota.com/recall using their VIN numbers.

Lawsuit

 In 2014, a class-action lawsuit was filed by frustrated Toyota owners who were looking for some sort of compensation for the expenses incurred from replacing huge amounts of oil as well as the expensive repairs required to fix the piston ring issue.

Unfortunately, the problems with the piston rings usually did not start happening until the powertrain warranty had already expired.

In response to this lawsuit, which has not yet been settled, Toyota initiated a Warranty Enhancement Program, allowing customers to seek reimbursement if they had paid for the repairs themselves or if they had not sought repair, which they could now have the problem repaired at a Toyota dealership for free.

According to the letter issued by Toyota, the Warranty Enhancement Program offers coverage until October 31, 2016, regardless of vehicle mileage.

After this coverage has expired, secondary coverage is offered from ten years of the vehicle's first use or 150,000 miles, whichever occurs first. The letter is individualized for each customer, so it should specify the VIN number of the affected vehicle as well as the official first use date.

What Should I Do? 

To properly fix the Toyota oil consumption is an extensive repair job that requires the engine to be taken out of the vehicle and taken apart. It requires special lifting equipment and tools that most people do not have in their home garages.

Toyota owners are encouraged to contact their local Toyota dealerships service department. Be sure to have your specific vehicle information on hand when you call, including the VIN.

This number is a unique identifier for your vehicle and it will help the service technician discover if your car falls under consideration for this repair.

If your Toyota is out of warranty and you can not afford to fix this problem, try using a thicker oil. Make sure to check the oil level every week. Do not drive your car if the oil light comes on. Switch to a thicker oil such as 10W-40. Thicker oil won't fix the problem but can slow down oil consumption.

Exact same thing happened to me. I bought mine at CarMax. Of course they deny knowing anything about this issue. If that's true, they shouldn't be in the car business. CarMax's job is to do due diligence so I don't have to. I still researched the car but never thought to check for engine issues. I have owned 6 Toyota's/Lexus over the years and loved them all. Toyota wouldn't budge once the 10 year limit is met. We only had 105,000 miles. They extended warranty to 150k or 10 years, whichever comes first. Problem occurred after owning it just less than a year. I would have never thought Toyota would have put out something this pathetic and then not fix all of them. They should fix each and every Piston on every damn car. To think we have to carry oil in the trunk of a Toyota. Pitiful!!!

I have a 2008 Toyota Camry with this oil consumption issue.  I would like to mention something I have been doing that may help others with the same problem.  When I purchased the vehicle (used), I changed the oil and filter to a synthetic blend as it was approximately 278 miles per quart of oil consumed (BAD!!).  When I approached a half-quart of oil loss, I replaced it with a half-quart of full synthetic.  Once I needed to top off with the other half of full synthetic, I noticed a gain of several miles.  I then switched to 100% Pure synthetic oil (Amsoil), and when I topped off after one quart, several more miles were gained.  By gradually introducing pure synthetic oil for each quart of synthetic blend consumed, it appears my mileage between oil top-off is greatly increasing.  Also, check and replace the PCV valve if gummed-up.   Oddly enough, the owner's guide stated that the maximum oil consumed expected within 600 miles is one quart!  I suspect they knew about the faulty pistons/piston rings from the get-go, thus the reason for printing such an absurdly low mileage for losing a quart of oil.  In typing this, it is my hope that others with the same issue may yield positive results as I have thus far by switching from synthetic blend to pure synthetic - it is well worth it.  I figure for every quart of synthetic blend oil consumed, by replacing it with 100% pure synthetic it should slow down the consumption rate (which so far has!).  This is perfectly safe to do so long as you are using the same weight/viscosity oil.  My plan is to drain/change the oil to a 100% pure synthetic oil fill, once I have used the equivalent amount of quarts to replace the synthetic-blend that was consumed to begin with.
