My 200,000 mile 2010 Prius burns 1 quart of oil every 800 miles and burns much more on the highways. Me and my girlfriend are Uber drivers in Columbia, MO. We drive 40,000 each a year for over 3 years now. This is my third, gen 3 prius. On this 2010, oily guck clogs small ports in the air intake causing the engine to run bad. The air intake then needs to be removed and cleaned. Whilst cleaning the intake manifold, it's simple and cheap to replace the PVC valve, as I did, and as everyone should do when working on this problem .
I saw no reduction in the amount of oil my car burned after replacing the PVC. After cleaning the intake, it took about 10,000 of driving before those small ports in the air intake manifold clogged up again. You know if they're clogged when you feel the car shudder, with an engine ping noise during an extremely low power band from the gas engine. This will happen at any speed, but only when the gas engine is barely throttled up at all. Like going slightly down hill on the highway. You will feel the engine shutter as it barely needs to exert any power. At low speed, you can hear the engine pinging. The power band supplied by the gas engine required to hear the misfiring and feel the shudder is lower than the electric engine needs to take off on level ground.
To help diagnose this problem, run the main battery down low enough that the gas engine needs to turn on. Your gas engine will then ping when barely taking off on level ground. You can also go up a slight hill at a constant speed around 20-30 mph and you will hear and feel the problem.
I learned how to put an oil catch can on my car by the amazing NutzAboutBolts2 videos. (Make sure you use a better hose than what comes with this catch can and give yourself a bit of tolerance in the hoses so you can remove the can and drain it.) My catch can will fill up after 10 hours of highway driving. That's about 600 miles of driving on the highway. City driving it fills up twice as slow. The more oil the car burned, the more that was in the catch can. My catch can contents look more milky though.
It's been 15,000 miles now since i installed the catch can and the engine is running fine still. So far my catch can has prevented the manifold from clogging up. My 2011 and 2012 "Prieye" don't burn oil and don't and may not need a catch can. But I think this catch can is keeping my oil guzzling 2010 prius alive! Good thing because I need to get another 100,000 miles and 3 years out of her until I have it paid for. Ugh...
THAT'S A SIGN OF FAILING PISTON RINGS AND EVENTUALLY CAUSE OVERHEATING DUE TO LOW OIL THUS CAUSE A BLOWN HEAD GASKET
@@21boxhead Yes, it has bad rings. The rate of burning, although bad, has not increased for 50k now. I always keep the oil topped off so it doesn't run out of oil. I am hoping that rate doesn't increase until I can trade it away. I've heard the 2011 and 2010 have bad rings. I just didn't know that until I bought one.
@@bobrainy5324 I HAVE A 2012 AND 2010 PRIUS
2010 PRIUS BLOWN HEAD GASKET AT 216K MILES OIL WAS BURNING LIKE CRAZY BEFORE FINALLY MISFIRES AND LOUD NOISES AND COOLANT WAS GONE
2012 PRIUS DOESN'T LOOK LIKE IT HAS ANY OIL BURNING AT ALL
IM AT 193K MILES
MY 2010 WAS BURNING OIL SINCE I OWNED IT AT 107K MILES BUT IT WASNT AS BAD BEFORE GOT 180K
STILL HAVE THE 2010 PRIUS ROTTING AWAY IN THE DRIVEWAY
I ALSO DRIVE FOR UBER
@@21boxhead where did you put the can under the hood? Indeed fills up after a 10hs drive?? Is it worse now?
@@capolihu WHAT? i DIDN'T INSTALL ANY CATCH CAN YET
Hi there - hope NaB still follows this thread. I recently bought a 2015 PiP with the -54 intake, normal cold-starts, 50-52 MPG in Hybrid mode, no oil consumption and no DTCs. The original owner had done 5k oil change interval. I just removed the air filter box, throttle body and EGR pipe for cleaning and inspection.
At 66k, the throttle body is clean on the top-side while the bottom had a smear of oil on the wall but the butterfly was clean. There was ~2 tablespoons of oil at the bottom of the intake. I didn't remove the intake, EGR and EGR cooler but the main orifices on the intake and EGR have about 1mm buildup so no blockage yet. The EGR pipe (elbow) had about 1.5mm of sooty buildup at the leading edge of each end but very little inside. Cleaning it with brake cleaner was easy. I plan to remove the whole EGR circuit for cleaning and replace the PCV at 70 or 75k.
Since you have an OCC, do you think it's really effective in reducing oil accumulation at the bottom of the intake? Although I like the idea of having the OCC, I don't want to remove the OCC, the intake, related hoses and put everything back to its original format for Smog Inspection every 2 years. As a maintenance routine, I will remove/clean the throttle body and wipe off the oil in the intake annually. Do you think that's sufficient w/o having an OCC?
Test the effectiveness of the can by inserting a cotton swab in the PCV side hose. The swab will have oil on it.
Insert a cotton swab in the intake manifold side hose. The swab should be very clean. If it is oily, the can is too small or poorly designed.
My DIY cans, one between the PCV/intake manifold and one between the engine cover breather hose/air duct, take out 99% of the oil.
No OCC is perfect. Most commercial cans will catch oil but the effectiveness has to be tested.
Effective OCCs will make all gasoline engines last longer. Vehicle manufacturers don't include them because of cost, extra maintenance, and longer-lasting vehicles.
My 2012 plugin has 85,000 miles on it and it never seemed to burn oil. However I followed your advise, installed the oil catch can, and yesterday after only 4,000 miles decided to empty it. I drained 30 ml out that otherwise would have gone into the engine and deposit carbon! BTW, I used the flexible metal straw from WD40 to insert into the can's dip stick hole and drew the oil out using a brake fluid change pump from Harbor Freight. Real easy since i could leave the oil catch can in place.
So thanks for the advise. I'll keep watching.
I noticed that the dip stick that came with my can which is visually identical to yours, is actually about 1 inch shorter than the can is deep. By the time you see ANY oil on the stick you will have about 20% of the can full. you can stick any thin straight object (metal coat hanger wire or bailing wire worked for me) in until it hits bottom to get a real reading, and also hold the bottomed out wire with your fingernails against the can top and compare the bottomed out object total length to the included dipstick length to verify that the dipstick is much shorter. I also recommend to pack the can with 2 of the corse stainless steel scrubs from the dollar store, as this will significantly increase your baffling, especially with these cheaper chinesium cans.
DO NOT use regular steel wool, as the heat and water condensates will rust it and it will break up and feed back into your intake. also DO NOT use any fine wool of any types as it will have a higher change of deteriorating the finer the wool is
Your videos are great and so helpful to us. Thank you for posting them. I so need to install my catch can.
The only thing I take issue with is how dirty that oil is. I would shorten the oil change the intervals to 6,000 miles, which is what the engineers originally noted for the 2ZR-Fxx engines. Considering how inexpensive 0W-20 is from places like Costco and filters/crush washers are on Amazon, that's a low cost, high reward investment for any Toyota.
I'd also consider a placement to a point lower than the PCV under the intake manifold as a more effective location. I think (at least on 4th gen Priuses) there's a couple of places it could go. If I recall correctly...
Hey NutzAboutBolts I really enjoy your Prius videos and so do a lot of people. I have recently been looking at getting an android auto 8.0 unit for my 2012 Prius. It would be really cool if you got one and possibly made an install video about how to get the steering wheels controls, and use the oem back up camera! I’m also interested in seeing a Clazio seat cover install on the prius. Hmm maybe they could sponsor you a video give it a shot!! Thank you for all the informative videos you rock my friend!
so I emptied my OCC (same one, but with 5ft tube split to maximize each section - I can pull it up and unscrew bottom easily) after 4k for my next oil change and got ~3mm of thin cream coffee like substance (more like colored water with fuel smell, not looking like oil too much.... better than burning it (now that I cleaned my intake and entire EGP coolant/pipe/valve - thanks to their other video).
I don't think I'm burning oil ('14 with 160k prev uber car). I didn't swab the out tube to see how effective at collecting oil though but will next time...
Love your Prius videos!
The problem is that Toyota knew about this problem. A "maintenance bulletin" was issued but they failed to tell the customers about it. And it wasn't just about burning oil but catastrophic engine failure. And these were in cars that were meticulously maintained, or so I thought, by the Toyota dealership. All turned a blind eye, the dealership and corporate when I tried to plead my case. I will NEVER buy another Toyota.
Well, Toyotas are far better than any other cars, reliability and smooth ride compared to Hondas.
First Comment.
I won the Prius.
Thanks for the awesome tutorial videos.
my 2015 has 160k and no oil burning.. cleaned the tb but no oil
I was abut to say in the install video that, that clear vinyl hose would collapse under vacuum pressure.
yeah, we were desperate because our black hose was too short. We'll be redoing it next time. :)
My 2011 Prius doesn't use any oil.
Looks like the "out" line is oily. So oil might still be going back to the intake. Maybe add some steel wool stuff.
That's the inlet.
@@jtrahan63 no if you look at 2:23 you can see the out (larger) having some oil stain so looks like it still going trough...
Yup, because this oil catch can doesn’t have a proper baffling system like how Mishimoto’s oil catch cans are made with.
Cool vid, is there supposed to be a filter inside the can? Does the oil that goes into the can supposed to recirculate back?
There’s no filter inside the can but people put steel wool in to capture the gunk, the only thing circulating back into the intake should be the fumes to burn again
Just wanted to thank you for the great videos on the 3rd generation prius's.
Just bought a 2012 and really love all your videos on it. Going to do the catch can mod soon.
Keep up the great work.
switched to 10/40 and use Lucas stabilizer and stopped oil consumption 2012 gen3
Do you use the Lucas stabilizer on every oil change or is that just a one-time treatment?
I thought about trying this. How is it suiting you a year later?
I moved the pvc and screwed into yhe out of the catch can. I also drilled a hole into the bottom of the can and put in a drain tube so it empty s by itself
It looks like the car burned 0.4 quart of oil over that 7000 miles, and the OCC caught less than 1/4 of a cup. If those numbers are correct, then the OCC reduced oil burning by 15%.
I was thinking about whether to install an OCC on my 2012 Prius, but the 15% improvement made me hesitate for spending the extra effort. Besides, the Prius has a port injection, not GDI, right? So that 15% will not cause much deposition on the valve. Could you please comment the necessity of a OCC for such a car?
Keep topping off the oil
Hello. I have a 2010 Toyota auris hybrid, it has the same powertrain than the 3rd gen. Prius. It has 138k miles (222000km) and it doesn't burn a lick of oil. I bought it used a few months ago. It differs from yours in the oil used, it has been using 5w30 for as long as I have records, I have castrol magnatec 5w30 start stop and no oil consumption at all. 0w20 might be a little thin, even though toyota reccomends it. If you use 5w30 you might stop oil consumption, it might be the reason mine was switched to 5w30, as 0w20 is what toyota recommends and this car was serviced mostly at toyota, getting 10k miles oil and filter change.
João Mendes My 2015 Prius burns no 0W-20 in 5000 miles
Here is the same but with 0w20 and no oil consumption at all for intervals of 10k miles. I do 70% motorway 20% city and 10% country lanes. Every second oil change I do stp engine flush and my engine and oil are clean as on s new car
5w = good for summer or hot weather. 0w = good for winter or cold weather. You will get problem with 5w during winter, it can be freeze like ice. Good luck!
@@MrLopez87 Where I live it rarely get's below freezing. We have very hot summers and not so cold winters. I can tell you for sure that it won't be a problem because the car has been wrecked. Got hit in the back by a truck
Thank you for the update!
Thanks for instructional and informative videos!!! I have a 2004 Matrix XR that is burning oil and/or piping oil from the PCV into the intake manifold. I am considering installing an oil catch can. Is an oil catch can useful for the EGR side?
@NutzAboutBolts time for a 6-month update? Any idea what parts they updated after 2010 besides the intake manifold?
QC Support the PCV valve was moved lower, causing the intake to fill with oil in the 2011-2015 models. An EGR valve and cooler was added in 2011, and the intake manifold oil problem causes the EGR to clog quickly with carbon.
I previously had a 2004 Prius and a 2010. Both models started consuming oil after 100k miles. Very interesting!
Hi there no my car has done 12500mil do u mean i have to clean the filter Off the EGRV valve
Anywhere now I don't have that vibration or shaking This now I can hear something noise coming from outside When excelerator or de exhilarating
You mentioned the 2010 and 2011 models, but the 2012 models seem to be improved. Is that the case for the 2013's as well? I've got a 2013 Prius V (wagon) and I stumbled upon your video about oil catch cans and EGR valve cleaning. On the forums they seem to be conflicting reports about the V's. Whats your take? Should I be concerned?
mines burning about a quart every 2500 miles. 2013 122k miles. Currently using the "Mobil 1 Extended Performance High Mileage Formula" Oil. I think i'm gonna try a castrol GTX oil next, i've had good luck preventing oil consumption with those oils.
Well detailed video. I followed your video and installed OCC successfully. I ran my Prius on maintenance mode for almost an hour ( to check if it's still overheating intermittently due to weak water pump that I replaced with new water pump and that's been fixed ) but I noticed the hose that I connected from outlet of Oil catch can that goes into the intake manifold was completely flat due to high pressure. Do you think OCC might not be functioning as it supposed to or should I replace with the heavy duty hose ( thicker one) , like the one I got that connects from PCV valve to inlet of OCC. Do you think I need to get a vacuum hose which is thicker than the one I installed ( maybe I got radiator hose ) . Thank you for you reply.
You need the oil resistance hose like the black hose in the video, the rubber hose that came with the occ catch can will flatten due to the engine compartment heat. You can buy the hoses at Home Depot or the auto store.
The strange thing is I had the engine compression (220 to 230 psi) and leak down (less than or equal to 10%) tested. The oil rings maybe worn and/or oil return holes are plugged.
what grade oil are you using?
Nothing is different between 2010 and 2012, because neither one had oil consumption while under warranty.
Does the oil burning have anything to do with the grade of oil? I've been using 0w-20 to date so not quite sure if that's a factor. I've also noticed that the oil only gets burned when full throttling, as when accelerating on the highway. Did a 1200 km road trip, started off near the full mark, and when I reached, the oil was at minimum mark. I have a 2012 with about 130,000 kms. All stock, no catch cans or nothing. Any advice?
It’s normal to burn 1 qt of oil every 5k miles. I’m still using 0w-20 and burn 2 qts every 10k miles. If it’s burning more, I’d check for worn piston rings or headgasket issues.
@@NutzAboutBolts my last 3000 kms were all in the city so NO wide open throttle. And it burnt ZERO oil. I check weekly. Soon as I take it to the highway and hit the floor past 120 kmph for a significant distance (100 kms - 500 kms), it will start burning oil. No visible signs of leaks at all. This isn't ideal as I have a road trip coming up! Does it sound like a PCV symptom? Or perhaps something else? Very peculiar.
I have a Toyota Prius 2012 and it has done 90000 miles my car's sometime shaking I don't know is it the same thing you explain on the video is it because of this I will check and thanks for Your video
Curious what has since happened. Head gasket-caused death shudders really are bad upon cold startup.
It's your injector nozzles. Clean then and the shaking will stop
My Prius go through oil like it’s gas. I don’t want to have to trade my Prius in because of this because it’s a great car besides this issue because when I had my bmw. The BMW was so.expensive to maintain.
Same!!!
Just keep topping it off
Is it normal to get the forbidden milkshake inside of your oil catch can? Whenever I do an oil change the oil looks perfectly fine but the stuff in the catch can sometimes looks fine but sometimes looks really bad
Yeah, it’s normal, it’s blowby gas and other particles in there from the engine. I get that as well, pretty nasty stuff
So ... stupid question... why not just dump it back in the oil fill? -- Thanks
You can, but it’s old oil
@@NutzAboutBolts thanks for the reply. On looking into this further, I think it's a bad idea. This is oil that slips past the rings, mixes with any unburnt fuel and exhaust gasses. Because of that mix, it is contaminated and should be discarded -- thanks
Use Ravenol Oil Extended DXG,Change Oil Every 3K Miles,No More Problems After That.
Hello, what oil can you recommend me for Prius 3 gen 170k ?
same 0w-20, what brand ?
my car consumes a lot between services I did at the dealer every 10k
Thanks in advance
I still use 0w-20, the car will consume 1 qt every 5k miles and it’s normal, anything more would be issues
@@NutzAboutBolts thank you for replay
👍👊
My 2010 Prius burns 1 quart every 300 miles the problem is piston and rings they changed ring part number in 2015 so that should fix oil burn problem using 2015 rings on 2010 year
Tengo un Prius 2012 sele prendió la luz del motor y tiembla y ase ruido que pueda ser?
Catch can is waste of money, it doesn't solve oil consumption issues.
It does save EGR and catalytic converter issues though. It's better to spend a couple of bucks putting in a quart of oil than buying a new catalytic converter, right? That amount of oil burned and lining the EGR and exhaust every 7k miles will take its toll.
Budget prioritization is a big picture thing when it comes to oil burning engines...
@@SeanPopify, you don't buy new catalytic converter, it's not needed. You going to have issues with vacuum and possibly check engine light on due to extra long hoses that decrease vacuum pressure.
@@repairvehicle Used Toyotas that have burned a ton of oil have a direct correlation with catalytic converter issues/failures. Here, in Southern California, catalytic converter thefts are all too common... Especially with (models featuring) 2ZR-FXE engines...
@@SeanPopify, oil consumption has nothing to do with catalytic converter. On the black market catalytic converter cost a lot of money, they have platinum inside which is more expensive than gold. I have never seen used prius with over 250k miles that had converter replaced.
@@repairvehicle
Our realities are different.
Can you link the kit you bought/installed on your Prius?
Occ can be bought anywhere online, the holder the person stopped selling the 3d print piece.
Imagine going through all this for a ten year old Toyota. WTF Toyota!
I guess in the Prius, the pistons were changed in 2014 and the piston rings were changed also in 2015, so 2015 has a different piston and piston ring set and 2016 has a different piston and piston ring set from 2015, so does anyone have a 2015 or 2016 with high mileage that isn't burning excessive oil?
I have a '14 with 160k and not noticing any oil burn so far (3k miles since I bought) but thinking of taking things apart look/clean.
I have 2 Priuses; 2010 Prius Base has 375k miles and 2015 Prius Two has 185k miles. Only noticing 2010 and 2011 Prius has oil consumption. 2015 Prius doesn't have any oil consumption (every between 600 to 1k miles). Did cleaning PCV valve, EGR pipe and cooler, intake manifold, Yellowtop Battery (recharge battery every 6 months), recharged/reconditioned Hybrid (HV) battery(recharge every during oil change), oil change every 15k miles on 2015 Prius only (w/ Pennzoil Platinum 0w-20 and Mobil1 oil filter), 5k or 7.5k miles oil change for 2010 Prius only(w/ Pennzoil Platinum 0w-20 and Toyota oil filter)(no high mileage motor oil needed), coolant change and so on.
you are misinforming people dude. This is a serious problem that deserves a recall. But Toyota will not do it unless we the owners of these cars file a law suit. The failure is defective piston rings with an approximate price of $10 per ring. But the cost of the replacement of these rings is somewhere between $1200 & $3000. So people don't listen these dude. He probably got money from Toyota to undermine the problem that would cost Toyota millions if not billions
TheJess Ylleg I don’t think you’re making much sense. This is poor engineering, sure, but not class action material. Most models of car have a horrible design flaw. The gen3 prius’ is in its PCV valve location; it’s that simple.
if it was class action material, then you would have no problem finding a lawyer to handle the case on contingency. Instead of being a paranoid nut job put your time where your mouth is and handle it if it means so much to you.
You are so RIGHT! Had a 2010 Prius and did assiduous maintenance performed by the dealer on time everytime here in Lake Park, Florida from 2010 to 2018. The engine self destructed on my wife going to work due to zip oil (burned) in the crankcase and this within 3 months between oil changes. The deaf ear shit that the service manager and one of the owners gave me was unbelieveable given the fact that they were in possession of a "service bulletin" warning of this potentially catastrophic problem. She's lucky, when the car stalled in traffic, she wasn't injured or killed. Up until this incident I was a true believer in the product and dealer. Prior to this documented coverup I had purchased two cars from these people within seven years. Thanks to the dealer's not giving a shit as well as corporate Toyota's deaf ear, I will never purchase another car from these people ever again. And I mean never. And I've made it my life's work to get the word out so too bad, so sad. They had their chance to own up and come clean but instead opted for the tactics of a film flam used car shyster. Buyer Beware indeed.
@@michaelbridges6102 Michael, you are either misinformed, a dealer or somehow on Toyota's payroll. If ever there was class action material this is it.
Toyota knew of the precipitous engine failure burning issue from corporate on down and covered it up. The extant "service bulletin" is the smoking gun and tells the tale.
@@ricksanchez2090 He's not a "paranoid nut job" and don't forget to pick up the hush money Totota's got you on the payroll for. This is much more about right and wrong and Rick I believe you know it. But if a class action is what it takes, Toyota and the dealers will bear the brunt of it and so it goes.
I'm surprised nobody is asking where you got the white bracket... I'm getting ready to install an OCC soon, but cannot find a bracket.
It was 3D printed.
if you follow the link in the OCC video, you can order one to be printed (I used ABS as it should be more heat resistant than Nylon or typical 3D print plastic). About $10, $14 for 2, shipped. Waiting for mine to come (2 weeks).
What would it happen if there’s no oil catch can?
Oil just puddles in the bottom of the throttle body.
@@NutzAboutBolts thanks I was thinking something serious would happen
How many miles on this prius now?
210k
Thanks dear. My mechanic told me two things about the my prius 2011, No 1: Not to open car bonnet once engine is running as it has lot of electric power and someone may get electric shock and No 2, it engine must not be washed with hose pipe pressure water. is this correct and should i follow the tips???
Not bad advice. The engine can jump on automatically by computer if the power button is on on.
2007 model Prius burns about 3/4 to 1 quart every 300 miles.
Have you tried a good high mileage synthetic oil ? Valvoline makes a good one. It should help. But that is a lot of oil, are you certain there is no leak?
@@nickhahn5412 yes I check the floor for leaks and nothing. I add mobile 1 fully synthetic. 5 -30.
Looks like its a big problem amongst the gen 3 prius owners. It seems to be shitty piston rings. I think a catch can would be a good solution. If you dont feel like replacing all
Those rings that is.
I have 2008 model and it’s burning the oil as well, I think it’s design issue, but other than that, it’s a great car
@@nickhahn5412 yes I thinking about putting a thicker oil. Maybe that might reduce the amount of oil burnt.
I would try castrol gtx in it. Non synthetic oil.
