Toyota Excessive Engine Oil Consumption, Burns Oil

Owner's of Toyota models such as Camry, Corolla, Matrix, Rav4, Solara, Scion xB and tC may experience excessive oil consumption. You will know if your vehicle is suffering from excessive oil consumption if your engine performance is severely diminished and if your oil levels are low too soon after changing the oil.

Some customers reported that the oil level had diminished to almost nothing by the time the maintenance interval arrived (typically at 5,000 miles for many of the vehicles affected).

Symptoms

Common symptoms include:

  • oil light coming on
  • engine noise
  • the engine burns least 1 quart of oil every 1200 miles.
  • having to add oil every month.

Oil Pressure light comes on halfway through your maintenance schedule (for example, if you normally have your oil changed every 3,000 miles, the oil pressure light comes on between 1000-1500 miles)

Affected Toyota Models

  • Toyota Camry 2007-2011
  • Toyota Camry Hybrid
  • 2007-20011 Toyota Corolla
  • 2009 Toyota Matrix
  • 2009 Toyota Rav4
  • Toyota Solara 2007, 2008
  • Scion xB 2008 2009
  • Scion tC 2007-2009

Affected Engines

  • 2AZ-FE 2AZFE Service Campain: LSC ZE7

Common Cause

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.

Technical service bulletin

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 amount of mileage.

The amount of mileage will vary depending on the vehicle and how new it is.

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

Test Procedure

2az-fe oil consumption

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, and then tells the customer to drive for 1,200 miles, and return to the dealership at that time.

  1. 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.
  2. 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.

Recall Info

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.

Toyota Oil Consumption 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.

he 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.

How to Fix Toyota Excessive Oil consumption

toyota oil consumption warranty enhancementTo properly fix the Toyota oil consumption is an extensive task that requires the engine to be taken out of the vehicle and taken apart, which 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 you using a 5W-40 oil grade can slow down oil consumption. Rember to check the engine oil every week and top off if necessary.

Toyota reminds me of Harley Davidson. They don't care. I've had so many issues with both I'm done with them. Currently an 07 camry with the worst ratings of all.we bought the car from First team Honda in Portsmouth va used and now are told it's on us. The service should have been done before purchasing but was not. Not surprising because we've had nothing but problems since the original purchase because this dealership does not check the history of trade ins and don't have a good check point system for resale, done,done, done

We have a 2008 Rave 4 since new. Never received this letter from Toyota. When i found out about this issue, and noticed was low on oil, went to dealer. It was the last month of the "ten year" limit. They won't let me see how much oil was in the vehicle when they "sealed" it. After 1200 miles, they checked it and said it was only down 3/4 of a quart, so "passed" test - no repair authorized. I checked it again after another 1200 miles, and down 1 quart. Have checked it every 500 miles, and more often. At 860 miles, 1 quart low. Have them top it off and give me an invoice showing miles, date and amount of oil added. It is getting worse - less than 500 miles and already 1/2 quart low. I am going to start adding some Sea-Foam in hopes that it will help remove deposits and free up the oil rings and slow the consumption. We have had many Toyota's in the past but no more. Amazing that Toyota admits there is an engineering issue with the pistons/rings on these engine, but won't stand by their products and fix it. NO MORE TOYOTA PRODUCTS.

I have 2012 Toyota Camry. It has around 97K miles on it. Every time when I take it to the Oil change service, they says car is running on no oil at all. Since this is know issue, why can't Toyota fix it. I have used 3 Toyota Camry and 2 Toyota Corolla but next time it won't be Toyota.

You should check the engine oil every two weeks and top off. Once you figure out how much oil it consumes then you can have a schedule to add oil on regular basis. My guess is that you probabily need to add about a quart a month.

They don't want to fix it becasue it means a complete engine replacement.

My local toyota dealership (Browns Toyota Glen Burnie) failed to properly handle this issue twice. I will never use Browns again and I will never purchase another toyota vehicle (even though I have been a lifelong toyota driver). Toyota knew this was an issue and Toyota refused to properly fix the vehicle.

Has anyone tried doing a performance oil change to break down the carbon or am I getting screwed?

I have a 2007 RAV 4 limited with 4 cylinder engine with 126000 K. I switched to Valvoline synthetic oil 5W20. They put a sticker with date and next mileage change. We put very few miles on the RAV therefore the date expired in Feb. 2019. It wasn't till April of 2019 that the shop added a half a quart. I checked it again just the other day and May 25th about a month later and I had to have another half quart of Valvoline 5W20 synthetic oil. Question, would it be better to change oil at the due date rather than mile date? Does the oil have a tendency to break down after the due date. The oil was change Nov. 2018. Thank you.
