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.

Questions? Comment or email please note that it takes me sometime to get back to you via email but I always will in the end.

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

Ex BMW master tech for 17years. Everything this man says is SPOT ON, imho. I would STRONGLY suggest following his advice on this matter!

[tonya.]

First time i ever heard an Automotive technician on YouTube say : I LOVE YOU ALL AND I CARE ABOUT YOU”
this man has a good heart ontop of being an excellent technician with excellent advice.
I could envision this guy being a teacher or professor and doing much good in this World. 👍🙏😃

[LostinMIA]

He is 100% correct! I work at a service department at a Toyota dealership. Folks just change your oil and filter every 3k-5k or every 6 months and your good.

[ralphstampone]

I have been an auto technician for 47 years. I have been telling people for years to change their oil and filters more often than the factory recommends. All the engine work I have done( like rings and bearings) were because of not changing the oil enough. Can't stress this enough.

[stanleykachuik]

Yep, I live in Canada. My father was a mechanic in the 60s. He taught me to change oil just before the snow comes and just after it leaves. My 06 Tacoma is still going strong. Thanks for confirming what my father taught me.

Quote from Scotty Kilmer below says it all:. "Oil is cheap; engines are expensive!" Sound and solid advice in this video. Well done!

[josephmarchitelli]

Excellent, excellent, excellent. I just bought a new Toyota Corolla hatchback and was told by the dealer you don't have to bring it back for an oil change until 10, 000 miles. As soon as I heard the words I cringed. While I'm not a mechanic by any means I have been working on my cars for more than 40 years and have always tried to change my oil between 5 and 7000 miles for synthetic and 3 thousand miles for non-synthetic. Thank you so much for confirming what I always thought was right. Keep up the good work with your excellent Channel. It's gentleman like yourself that make YouTube a excellent tool for the car enthusiast an average guy alike. My Compliments sir.

I've had my car for 12 years from new. I'd always changed the oil and filter every 5000 miles with mobil 3000 and OEM filter. The car now has miles on it, I just inspected the cylinders with an endoscope. Still has the cross hatching and very few faint vertical scoring. Listen to the guy, he knows what he's talking about.

[brianwalp]

Hello, I have been a Toyota Master Technician for about 30 years. I own a 2005 Toyota 4runner limited 4.7. I change the oil every 3000 miles. I now have 300, 000 miles on it and it still running strong! I keep telling my customers the same things you are talking about and I wanted to say great job on the video 👍

[stanwardoshiro]

I’m a mechanic and this guy speaks 100% truth

[TommyBoy]

I follow your advice.
Change oil every 3000 or 6 months ...
1000 miles 1st oil change..not 10, 000 miles.
As with my so called free oil change which I paid for.
Everyone tells me I'm doing to many oil changes.
My response is, has any mechanic told you that your doing to many oil changes.
I share your advice.
Its cheaper to change oil then an engine.
Thanks..
Appreciate your videos..

[spirosfoufoutos]

One can tell that this guy is a great mechanic and it's telling the truth by how frustrated he is.

[cubsfan]

Recently purchased a 22 Tacoma. At 5000 miles I took it to the dealer for its first complimentary oil change. The dealer refused. Said you don’t need to change till 10000. I told him I am in the severe driving category. After going back and forth with him I left and went to jiffy lube. Really like your channel. Keep up the good work.

Hi AMD. I’ve been in the aviation maintenance industry since 1976. I’ve always done my own auto maintenance and felt like I knew quite a bit about maintaining my vehicles, but watching your videos has taught me many things. Your knowledge and expertise is a valuable resource for myself and countless others who want to maintain their vehicles. Thanks and God Bless you, your family, and the others who watch and learn from your videos.

[TheAmerican]

Have 2016 Gen 3 TRD Offroad Tacoma change every 3000 since new NO OIL CONSUMPTION 116, 000 miles and counting you are a treasure, Sir Thank you for what you do !!!! 🙂

[kevincosby]

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.

[zzanatos]

I have been using Mobil 1 full synthetic every 5, 000 miles in my old 4Runner since it was new. It is now nearing 200, 000 miles and still runs like new and does not use any oil. When I started driving, my dad taught me that the number one most important thing to make your car last is to change the oil frequently.

[ProfessorFate]

In the 1960-70’s mechanic Smokey Yunick wrote a column in Popular Science magazine. I’ll always remember what he wrote; “He who spends the most money on lubrication goes the furthest the cheapest.”

[wailingalen]

Wow this man is a gem to all of us. I’ve been doing a lot of research, and I have a Jeep, not Toyota and the story seems to be the same there. Some of the problems they are having with the valves and camshaft stuff is because of insufficient maintenance, ie oil changes. The more research I do the more I am convinced that it is imperative we half the intervals from these manufacturers from 10, 009 down to 5009. 4000 even… if you drive in extreme conditions.

Thank you for your honesty… I know its kind of a conflict of interest, being that you work for Toyota, but this is stuff that is people need to know.
