Why do Toyota engines consume oil ? And how to prevent it?

A Toyota Master Diagnostic Techncian discusses Why do Toyota engines consume oil or burn it. And ways you can prevent it from happening to your Toyota
In this video I go over a very hot topic, Toyota engines burning oil? Not only the 2AZ-FE engine that was part of a customer support program and was fixed because of a problem. But the newer engines are also using oil like the 2.5L 2AR-FE , 2.7 1AR-FE and the 2ZR-FXE 1.8 engine in the toyota prius.
I will go over what is causing all this mess and you guessed it. Low tention piston rings. This is a change that took place in modern engines that makes them very tempermantal to oil maintenace.
The No.1 cause of oil burning problems in modern engines not just with Toyota but with everyone is low tension piston rings sticking or seizing because of bad maintenance habits.
Toyota's 10,000 mile oil change or 1 year is great to reduce the costs of ownership. However you must adhere to the strict guidelines for this oil change. There are many condtions which would change your car to Special operating conditinos which would then call for a 5,000 mile oil change or 6 months whichever comes first.
I wish all my viewers and everyone who watches this video to know about this and understand that going into the grey area of special operating conditions is not worth it. Toyota overall maintenance costs are very low even with the 5,000 mile or 6 month oil changes. Why push your engine to the edge or keep wondering if you operated your car in special conditions, Just do your oil change every 5000 mile or 6 month and wonder no more.

I worked for a car manufacturer for almost 3 decades. Every engineer from power train group I ever worked with was not favorable to long drain intervals. The environmental impact of waste oil and competitive pressures for low maintenance costs pushed their managers to do it. The reduced water jacket height in block and oil spray jets allowed oil to get to evaporating temp for fuel and moisture and better oil all got them to the best result. THEN reduced friction was the goal and ring width and spring force were one the first and easiest things to do to reduce effort needed to turn engine over. High output demands then got us turbochargers. The ring heat and more plastic like particle formation got the ring groove sludge build that sticks rings. The basic indisputable fact is that ANY oil gains contaminants with engine use hours. Dirt particles smaller than air filter capture size and fuel that is not combusted that is on cylinder walls and is scraped down by rings will accrue in the oil. Synthetic oil is better at tolerating this but it is still oil and still accrues the same stuff. Superfine bypass flow oil filtering can get the particles but still you have the other dilutes building up. As stated, ONLY MORE FREQUENT OIL SERVICE fixes this. So you buy a prepaid maintenance plan and it only covers the standard schedule? Find a trusted quick lube and get the base service oil change. If you keep the car it will pay it back. Even without ring concerns the overwhelming bulk of vehicles have timing chains and variable cam timing. Those c omponents suffer from the dilutes in oil causing wear not seen in 150K mile engines with more oil changes done. Camshaft in hemis, tappets in GM V8s, and cam phasers in some Fords? Not seen much at all when the oil changes were done at 5K interval. Listen to Car Care Nut

Thank you for sharing your expertise! This is the non watered down version of this video! And it’s very well said! I have been humming this drum for a long time. Automotive Engineers are pushed to their limits and then some with strict emission standards and an ever changing automotive industry.

I love hearing guys calling coyotes and hemis crap when their beloved LS eats a gallong of oil every hour and taps away like an impatient drummer all because they're either too lazy or too stingy to put in the extra money/effort to properly care for their engine.

[@smh9902]

Petroleum derived lubricants whether its made via hydrotreating, hydrocracking, or catalytic reformation, does not provide nearly the same level of protection that a good PAO and diester basestock synthetic oil does. For example, petroleum derived lubricants will fall off the cylinder walls within 48 hours due to gravity and leave your cylinders virtually dry. When you crank the engine over, for a few seconds your cylinders will be running completely DRY and cause asperity formation which leads to galling. The resultant by-product of asperity formation is the iron particles you see in your used engine oil. There is also the aspect of "severe" operating conditions (extreme high or low temp) which alters your oils viscosity. In very cold conditions petroleum/mineral derived motor oil has small amounts of residual waxes in the oil that crystalizes. When this happens, the viscosity increases to the point of being unusable. There are no practical methods to prevent this other than the use a motor oil that has a much lower viscosity than that which is ideal for the engines operating temperature. This creates a conflict that was "solved" by viscosity index modifiers, which are added to a low viscosity mineral oil to prevent a total loss of viscosity at engine operating temperatures. The problem is that viscosity index modifiers are long chained polymers that work by swelling via molecular expansion, which isn't bad per-se, except that the extreme forces and pressures from the babbit bearings causes these unstable long chained polymers to break down. This is known as "shear losses" and cause the oil to become unusable in a rapid period of time. A good quality synthetic oil is inherently stable across a much wider range of thermal operating conditions and thus doesn't need viscosity index modifiers to retain its viscosity at low and high temperatures, making it comparably insusceptible to shear losses. This is just ONE of about a dozen core fundamental aspects of motor oil. We haven't even got into total base numbers, the importance of ZnDDP, pour point depressants, borderline pumping temperature, anti foaming agents, oxidation inhibitors, detergents & dispersents, corrosion inhibitors, anti-wear agents, tribological additives, and much more. I could go into super crazy autistic details and write a whole book on the subject, but fortunately other people already have.

[@robertjackson7590]

@@smh9902 I have a 2010 MDX with 289K running syn oil the whole time, extended oil change intervals. Usually in the service manuals it will state "If you live in extremely hot temps you should go to a 10W-30 oil". I'm convinced the OE's are using the thinnest oil that get the best EPA mileage return and not so much for longevity. I've been told they use non ethanol gasoline for this testing because higher mileage is attained. As best as I can tell from the consumer standpoint the thicker the oil the thicker the film strength that with an aging engine benefits very well. Syn opposed to petroleum base are old rotary dial compared to current cellphones. Scuffing bearings and cylinder walls are contaminated oil or lack of oil but sticky oil control rings are in direct relation to compression rings sealing. The thicker oil serves to lessen this problem. The PCV system is in direct relation to oil contamination and as the engine has more miles might be the most neglected system in the engine.

While this is on a 35 year-old 3FE in my FJ62, I was losing about a quart every 3K miles. Fortunately it was collecting into my PCV catch can that I regularly had to empty, so it wasn't getting pumped through the intake to be burned in the engine and foul the plugs. A couple years ago I pulled the valve cover and hot tanked it, thoroughly clearing out the baffles and their drain holes on the inside. New valve cover gasket and bolt gaskets, put it back on, and now I only end up with an ounce or so of oil collected in my catch can every 3K miles, and no perceivable loss showing on the dipstick when I change the oil. Had I not added a catch can to keep my intake clean about 20 years ago, I would've gone nuts trying to find out where I was losing oil. Fortunately for the past 25 years or so I've religiously done oil changes every 3K miles and use Mobil 1 High Mileage, substituting a quart with Marvel Mystery Oil, and it comes out just barely darkened when I drain it. Granted this is a different scenario from those that you discuss, but for those trying to find out why they're losing oil, the PCV is something else to consider.

[@LouieGMDesign]

I had a 2014 Accord Sport. I always changed my oil at 5K miles and only used Mobil 1 Extended Performance oil, thinking it would help keep my car's engine protected. I did this until recently when my car had reached 165,000 and I just started changing my oil every 3K. I only did this because of the bad oil consumption issue and the dealer recommended it. It was probably too late to make the change; the piston rings were probably wearing. The Honda dealer eliminated the valve seals since no oil was in the spark plugs or the wells. And it seems like all mechanics and dealerships stay away from changing out the piston rings, maybe out of laziness or lack of motivation. So lesson to learn. Even though Mobil 1 Extended Performance oil is rated at 10,000 mile oil change intervals, does not mean to do it with higher mileage vehicles. It's best to listen to the experts and mechanics when they say that after 70K miles, start changing your oil every 3K miles.

Excellent advice. I bought a new 2021 Tundra w/ Toyo Guard that provides a couple of free oil/filter changes. At 5k miles and again at 10k, 15k I arranged for this service. Each time I walked up to Service counter I was told this service would be a full charge expense to me because I didn’t wait for the first 10k for the first oil change. I was calm but livid that after purchasing a vehicle over $50k they were the ones to determine the mileage qualifies for the free oil/filter, not what the customer believes is good for their vehicle. After instance and stating I am the one who will own this vehicle after 36k miles warranty, they agreed to provide the service as requested. Note, I also change my oil the first 800 - 1000 miles. I use Oem filter and 0-20 Mobile synthetic. I do this because engine blocks used to be, and probably today, are cast in sand. If not, I still do it because I am looking for initial engine break in with possible metal fragments that will be seen through the still clear oil.

[@ryanyoung9953]

@@101yen Since new 0w20 is usually under the ILSAC GF-6A certification, that means higher standards are set for that oil compared to the last generation (GF-5) which I haven't yet seen a GF-6A oil that's conventional base stock. The interval at which you change it sounds great and beneficial to your engine, especially since it's such a thin oil that can lose it's viscosity from usage (mileage). I still believe that 6 months on-the-dot is a little overkill for newer oils as synthetic base stock keeps getting better over time which means additives and antioxidants are also improving and are more plentiful in oil. My recommendation for oil changes are max 1 year for most long-commuting drivers (people that run the engine for at least 15 minutes which removes moisture and activates some of the additives) or 8-9 months for short-commuting drivers that don't have the engine running for very long. As for mileage, I say no more than 5,500 miles on the oil. Which ever comes first though.

As a newly licenced driver, I took Smokey’s advice to heart, retrofitted seat belts, and drove with my lights on. Both item caused great consternation. Some drivers nearly drove off the road while frantically signalling to me that my lights were on. Now of course, seat belts and daytime running lights are the norm.

Thanks for the video. I recently brought my new Toyota in to the dealership for the first 5,000 mile inspection and ended up leaving without them touching it as they only wanted to do a visual check of the fluids. I asked to have the oil changed and the service guy said he has 6 ASI? certifications and assured me I was wrong for not wanting to wait until 10,000 miles. After finally agreeing to change the oil, he said it would be nearly $100 plus tax so I said forget it. I've always changed my own oil and had it not been for the "free Toyota Care", I'd never have brought my truck in to the dealer and surely wont again.

[@colty7764]

as was mentioned in the clip above, damage slowly increases up until maybe the warranty runs out (with 10k mile intervals), but later the damage grows exponentially. So if you started out following the 10k interval recommendation, you can prettu much halt further degradation by going less than 5k/6 months when you get past 60k on odometer. Best to start this as early as possible, but not too late if you still don't burn much oil yet.

I've owned several 2AZ's, 1ZZ's, 1MZ's and 3MZ's that have gone over 300,000 miles with no oil consumption! It's all about oil quality and change intervals. There were all serviced at 3,000 miles with Mobil1. Even 3MZ's with oil gel issues weren't a problem with proper maintenance schedules and quality oils. In the case of the 3MZ's I've been told by numerous Toyota FTS's and Product Engineers, that the gel issues they experienced were due to intentionally increased combustion temperatures to reduce NOX emissions! Your videos are largely spot on and you should be commended for keeping the public properly informed!!! As some others have commented Toyota has extended there service intervals to reflect lowered operating costs and reduce environmental impact.

I work in power plants running gas turbines, what’s odd is they told you high temps lowers NOX, that’s the opposite of what’s true.

It’s a trade off but we have to monitor and tweak water injection for emissions in power plants.

Excellent video, I check the oil on my cars and chage it when it gets to about half way black on the dip stick which is approximately every 3000-5000 miles. Always use full synthetic and only top up when the oil is somewhat translucent. Every car is different and sometimes driving habits change. I use trip B to log how many kilometers since previous oil change. My engines always start and run smooth Take care of your engine and the car will take care of you.

[@donnatalielucasheimbigner7598]

First, I only watched this video because I couldn't believe there was a Toyota that suffered from oil consumption. Second, great job of explaining everything at a level that I think most people will easily understand. Third, you are ABSOLUTELY 100% correct. If you read all of the disqualifications, there are very few (almost NONE) driving conditions that allow the high mileage, long term oil changes. And yes, use good oil & an OEM filter. I have 4 domestic (3 Fords & 1 Chevy) vehicles with over 400,000 miles on the original engines. The one with the worst oil consumption loses 1 quart before the 3000-3500 mile oil change. Also, no matter how many miles you drive, NEVER go more than 6 months (3 in high humidity or changes in ambient temperatures ) between oil changes. The water vapor in the air mixes into the oil which will cause sludge build up in low concentrations to forming of corrosive acid in high concentration. Either case will obviously cause severe engine damage. Another no no is using real good oil with a cheap (including Fram) filter. Wal Mart stocks several OEM filters for under $5. Think about this, 5 quarts of Castrol & an OEM filter for less than $25.. Average cost to replace the engine runs around $5000 and will usually have about a week of down time. That means you can change the oil 200 times at an average loss of 30 minutes each, yielding a staggering 800,000 miles for the same $5000 at 4000 mile intervals $5,000/$25 =200. 200*4,000=800,000. This assumes that you have performed the labor yourself. If you spend $100 each oil change, you will still equate 50 oil changes or 200,000 miles per engine swap price.

[@matticus6339]

Thank you for your honesty. It once again proves the point I have been making for 25 years and it applies to every engine, that the single most important thing you can do is keep your oil changed every 3 to 5,000 miles or once every 6 months or once per year if you don't drive 5,000 in a year. Oil is the life blood of an internal combustion engine.

I know that that is putting a lot more wear to the truck since it's a good amount of weight being towed twice a week. I am a firm believer in using a good quality oil just as you said, I personally have used mobil 1 full synthetic for years and have had great success. And I change it every 5,000 miles. 95% of the time, I'm changing it 500miles early. I'm a firm believer in oil change intervals, I never go by what the manufacturers say.

Thank you for the information AMD. I learned so much from this video. My van has the codes P0304-0306 and P0420-0430. These are misfires and catalytic threshold issues. Also, it consumes 2 quarts of oil per week. Moreover, recently, my van cannot get past 2000 RPM. It is grounded. So I stuck my borescope in my front cat, and the substratum is gone. I looked in my rear cat; the substratum was gunked up with dried oil. I think the front substratum broke up and clogged up the under-the-floor cat. I'm going to look in my cylinder wells with my camera and see what it looks like this weekend. Also, I will do a compression test. But it seems like a foregone conclusion that my van is a goner.

[@joep.8805]

Don't forget that those short trip generate a lot of condensation in the engine block too. So if they don't have extended drives that heat the engine and oil enough to "boil off" the water you contaminate the oil even faster. That is why when remove the oil fill cap you will find white/grey foam under the cap. Seen that too many times.

[@SarmedAmeen]

Thanks man!!!

[@redlywaxer]

Yes, the shorter your trips, the more often you must change oil due to the water moisture and acidic combustion gases that get past rings and condense in the oil pan, using up the precious acid reduction additives in the oil. Short trips reduce the TBN or total base number of the oil, requiring oil change sooner to prevent oil degradation that leads to deposits in such areas as the ring grooves on the pistons. Longer trips heat the oil up enough to essentially boil off these contaminants and send them out the crankcase PCV system to be reburned in the engine before they use up the available TBN in the oil additive package.

Been a mechanic for 20+ years and I never realized the time factor on oil changes being related to fuel contamination. I always just assumed it was due to moisture and acid. Good to know! Thanks!

[@charleshines1553]

Just a very serious engineering flaw that should embarrass ALL Toyota employees for life for letting this happen! I almost got sick from being behind a Buick Envision with a serious emissions problem, UNACCEPTABLE!!

[@cg205s]

Love this. Thank you my guy. Explained a lot for me.following you. I have a master mechanic and my dealership was giving me run arounds to pick the engine out when I already can have that. Saw the Diagnostics from the dealer and they mine as well be the “new car” seller lol I appreciate this post my man! Thank you.

As a retired Porsche technician I agree with your opinion,I own a 2018 Camry with only 60k miles,I do my oil changes at 6k miles she uses no oil but I never drive the car without completely warming up the oil which take a lot longer than the rest of the engine.I love your show.

This video is very informative and very well put together. Thank you for giving many drivers out there the engineering perspective of why and how to mitigate it. You’re an honest man. Thanks!

[@critterallywithjohnernest.]

You are such a wise man. Thank-you for helping everyone and breaking the facts down. I work in reman and re-sleeve, bore and hone blocks everyday. I see these scored walls everyday.

[@m-rezaabazar-ghafari8757]

You are so right, as I do exactly like you do, changing oil every 3000 miles with full synthetic is the best medication and remedy for the engine. You are a great man and best master technician, those who criticize you are only fool people, they don't deserve your valuable education. Thank you for your effort.

[@jamesgerboc]

Thank you. Very important truth everyone needs to understand. Just wanted to mention, I just asked Audi to re-program our car for a 5000 mile reminder and they can't or won't. That reminder is an important convenience.

[@normandauphin1066]

I agree 1000% with you. Changing your oil is the single most important thing you can do for your engine.

[@patientx77]

I can’t help but think that 1 qt every 1200 miles is considered “normal” because they (not just Toyota but others as well) don’t want to have to pay for expensive warranty claims.

[@TuanNguyen-pp4uo]

My Altima 250k not a drop of consumption.

[@96cr]

your are correct they do not want to have to put a new long block in it

[@sukmahdik69]

You sir, are a national fricken treasure!! Keep fighting the good fight and I'll keep enjoying your thoroughly informative videos.

[@deborahgreen8887]

I over maintain all five of my cars, and yes, oil today costs a ton of money, but it is so worth it. I use only factory parts and good quality oil. One of my cars is a 2008 Toyota RAV4 with the infamous oil burning engine. I keep an eye on all the fluid levels. Another great video sir.

[@Norm100ful]

Thanks for taking the time to make this video. You explained why my son’s Acura started burning oil. He makes short trips. Luckily, we began 5000 mile oil changes as soon as we noticed oil consumption between changes. The Acura is now using about 1 quart between changes. Also, we use full synthetic oil. If you really want to know how your oil is performing, get an oil analysis by Blackstone. One more thing, if you have a turbo charged engine, you need to change the oil frequently because it breaks down, regardless whether it’s synthetic or not. That is when the Blackstone analysis is worth doing, also.

[@joe1071]

For sure with the turbos. My twin turbo starts to smell heavily like gasoline after a couple thousand miles. Super high compression and blowby. I change the oil every 3,000

[@jabomiles6947]

This video makes so much sense. My 2020 highlander states 10K oil changes, but my maintenance reminder comes on at 5K miles. Thank you, you probably just saved me a lot of trouble.

[@robertchen8297]

Thank you for your video and the constructive comments from repliers. I learned a lot from you all about these fascinating aspects of engine issues.

[@LoosleyLouise]

I have a Ford CDRA engine, change mine at 5000, no oil burning, no problem, watch this guy, he knows what he is talking about

[@josephbingham1255]

Very interesting! You might also like the oil story about early Aston Martin DB5s. The sump was so small that at high prolonged speed almost all the oil was in the passages leaving a low sump that began sucking air. The book I read was the people in Italy that were driving at high speed and destroying engines under warranty was so frequent Austin Martin stopped answering their telephones!

[@MaliceInCyberland]

You are absolutely correct! I think a person such as yourself will find this very very interesting: I know a girl from Hong Kong who's father rebuilds 2AZ-FE engines for Toyota. He gets the engines free from Toyota Dealers in the USA, rebuilds them, and then they go into 07-09 cars which have the 2AZ-FE engine which failed Oil Consumption Tests. Since he works directly with Toyota, he found out some inside information... Every 07-09 car with the 2AZ engine had problems if they took their cars to a Jiffy/Quick lube who used 5W-30 for every car and waited 5K miles to change... Those 2AZ-FE engines had ZERO margins for thicker oil because of the few and small oil return holes in the piston, and the oil return ring being too small with little tension. The Toyota Dealers had a trick to prevent profit loss and engine replacement time... They put 1 cup of Seafoam in the crankcase, ran the car on idle 30 minutes, let it sit overnight, and then changed the oil with Mobil 1 5W-20 Synthetic. Many engines then passed the Oil Consumption Test after 1,200 miles... moreover, those engines didn't burn oil, or very little, thereafter if they ONLY changed oil at the dealer using 5W-20... The engines that were ultimately replaced had OVER 80,000 miles, oil changes at Quick Lubes using 5/10W-30, and they waited until 5K+ miles to change... Like you said, "Change oil often!" That is definitely the case with the 2AZ-FE engine, and NOTHING THICKER than 5W-20... So basically the 2AZ-FE is a GREAT engine and can last 500,000 miles+ if the oil is changed before 5,000 miles, and only with 5W-20... Thanks for your excellent videos...
