Toyota Engine Oil Consumption Excessive

Owner's of Toyota models such as Camry, Corolla, Matrix, Rav4, Solara, Scion xB and tC may experience excessive oil consumption. 

Common symptoms include the oil light coming on or having to add too frequently. This article provides details on affected Toyota model years, test procedures, and possible fixes. 

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.

    1. Toyota Excessive Oil Consumption 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.

    Why isn't there a recall for Toyota excessive oil consumption?

    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 is the cause of excessive Toyota oil consumption? 

    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.

    2. Symptoms of Toyota Engine Oil Consumption

    toyota oil consumption?fix 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)

     The engine burns through at least 1 quart of oil every 1200 miles.

       The engine runs out of oil before it should and reaches dangerously low levels.

    What to do about Toyota Excessive Oil Consumption Problem

    toyota oil consumption test costUnfortunately 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 Test Procedure

    toyota service bulletin rav4 oil consumptionYou 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 fluid levels in the oil pan had diminished to almost nothing by the time the maintenance interval arrived (typically at 5,000 miles for many of the vehicles affected).

    If you change your oil, then drive for 1000 miles, and you check your oil level again and it is low, then it is likely your piston ring assembly needs to be replaced and may be affected by the oil consumption problem.

    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 power train 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.

    Possible causes

    Excessive oil consumption can result from two problems:

    1. Oil is leaking out of the engine because a gasket or other seal has been compromised. 
    2. Oil is burning at an abnormal rate. As stated before, it?s normal for the very small amount of oil to burn. Burning a lot of oil is not typical and indicates a bigger problem.
    How to troubleshoot or fix it

    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 dealership?s service department to find out what the first steps are. 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 may want to try using a 5W40 oil grade which may slow down the oil burning.

    Thanks for sharing this information. My Toyota has been burning more and more oil over time. Now it's at the point where it's too much.

    There is a pending class-action LAWSUIT that we should consider jumping on-board with if Toyota continues to give us the run-around to avoid repairing their mistake! They will continue to give you the run-around until your car reaches or exceeds 150k miles which basically dis-obligates them to repair. But I'm still researching. I have to continually add up to (4) quarts of oil in between oil changes; however, after a couple of consumption tests they claim it's normal for a car to burn more oil and it gets older and I have to continue to check and add to oil levels. This is bogus!


    I just finished my Toyota 2007 Camry w/59030 miles to finish the 1000-1300 test for excessive oil consumption (eoc) I requested the service tech that I stay and watch when the dip stick untapped, within 15 minutes they had me in the front waiting room, where the vehicle was moved into the back room, 10 after that the service adverser get me and we both walk back to the where my vehicle is on the floor over an lift.

    They are trying to drag it out so that your vehicle exceeds the 150,000 miles, and then they are not required to fix it under the second provision of the agreement following the class action lawsuit. I have gone into RedMcCombs Toyota and have gone thru (2) oil consumption tests, and according to them, it passes each time. Bullshit. I have to add 4 quarts in between oil changes. May consider hiring an attorney and parking the car since it's already at 130k miles. Toyota is simply trying to avoid the cost of repair THEIR MISTAKE.


    Was having excessive oil consumption test done on 07 Camry with manual transmission. At 1100 miles driven since test started when check engine light came on. Dealer said check engine light not related to oil consumption issue but my car did fail oil consumption test. Are performing repairs for oil consumption but charging me $480 to replace O2 sensor to address check engine light. Dealer is adamant they are not related.


    My Toyota Camry 2011 SE is always short of oil. Though, no oil alert displayed on the dashboard yet but i need to know why its always short of oil and also whenever i start the car in the morning, it gives a funny nice for like 5 secs. Could this be as a result of short of oil? Please i need answers. Thank you


    I own a Scion tC 2007. I am the second owner of the vehicle, yet it is paid for. I bought the car on January 5th 2013, with around 117 thousand miles on it. For about 4 months my car has been consuming a lot of oil, yet there is no leak. I have to put oil in the car at around every 1200 miles. I love my car. I went to Toyota to ask about the issue they said that I qualified for an oil consumption test so they scheduled me for an appointment. So that I can drive the amount of miles listed to see if I qualify for an engine rebuild.


    I failed the oil consumption test back in November at 89,000 miles on my Tc. Repairs were made and starting March of this year I have a low oil light go off every 2,000 miles. When I brought the car back and complained they said that Toyota "recall" only covered pistons and valves on the bottom part of the engine not the top. The top part-valve seals, timing chains, etc. aren't covered and that will cost me over 2k to fix otherwise I will need to do an oil change every 2,000 miles. And at 2,000 I am completely out of oil-stick is dry. This just sounds wrong.

    I have my oil changed every three thousand miles. I last had it changed 2 weeks ago. Have driven quite a bit with family issues. I then had to make a trip to Warroad which is a littl over 400 miles round trip. I checked my oil before I left, it was good. When I got back to Virginia, MN the oil light came on. At that point I had to add three quarts to my car. I do not believe the driving I had done after I got my oil changed should have gotten that low that I would have had to add three quarts.


    Wife had less than 3 minutes to react to the low oil pressure light and barely made to the shoulder.
    got it towed to dealership
    they said it had seized up due to no oil.
    this is the "REFURBISED" engine that was taken in because of this problem originally... they didn't fix a thing and we're out
    of a very well taken care of RAV4 (immaculate condition)
    they even had the nerve to say "you're welcome to browse our line of new vehicles"
    to spite that .. we got a top-end suburu outback. LOL!
    they missed out, bit time (we Spent ALLOT!)

    I took my Toyota Rav4 to my mechanic for the test they do at the dealership and it was down 2+ quarts in 1200 miles. When I took it in to the Toyota Dealership in early 2016, the guy that met me in the service line asked what I was there for and as soon as I told him, he said, that's $800 right off the top for me (said under his breath, but loud enough for me to hear). NOT MY PROBLEM. They then kept my car for 2 1/2 hours and said I needed an additional $700 worth of work done before they could perform the oil consumption test.
