BEWARE!! Toyota Prius Burning Oil

[@joskd8491]

You should clean the complete EGR-system (EGR-cooler, EGR-valve and the intakemanifold), replace the PCV-valve and install new spark plugs. And change the oil every 6-7000 miles, with a good quality oil The reason the noise is there is that the small canals in the intake manifold are clogged with carbon. When accelerating gently the egr valve opens and lets exhaust gasses through, to your intake. Because of the clogging the amount of air for every cilinder is not even, which causes the rattle

i would suggest an oil catch can as well

[@mollyz2581]

Please, people, for the love of God, CHANGE YOUR OIL AND FILTER EVERY 5000 MILES OR 6 MONTHS

[@Funkydood]

I suggest you upgrade to 5W-20 (5W-30?)!

[@brucewayne2773]

The biggest mistake owners of all these 2010 to 2024 Toyota has been doing oil change intervals at 10k . I have always done my oil changes at every 5k miles . Since new, I always do the first oil change at 1k miles. FYI all 2012 to 2017 Prius V all have identical powertrain. I've always serviced the EGR, EGR cooler, full intake manifold cleaning and PVC cleaning. My 2010 Prius has 250k miles, zero oil consumption between oil changes. Biggest mistake with head gasket issue has been lack of warm ups ( I always let my Prius warm up a minute or 2 before driving off in the mornings( with the car in park, step on your accelerator once and engine will come on, engine will go into ev mode when it's warm), and people driving their Prius too hard going up the grades.

[@thailam9512]

Not only Toyota. Any car, always have the problem with oil change at 10k intervals after 150k odometer (doesn’t matter how quality and fully synthetic oils). Please do an oil change at 5000k OR 6 months whichever come first so you will be safe for 400000 km easily

[@waynehung4801]

For the metallic sound, it maybe an indication of LSPI, you can try with new API SP engine oil which may help. Secondly, the oil change interval need to be reduced to 5000 miles as I would suspect the piston rings maybe stuck. You can also try engine flush eveytime oil change took place to remove as much sludge in the engine as possible. Also add fuel additive from Redline to clean the intake valves, injectors and combustion chamber. I know Amsoil has twice amount of detergent within the oil which you may also considering. The stuck piston rings is mainly due to long oil change interval, I mean 10,000 miles oil change interval engines always end up bad. Only use synthetic oil not high mileage oil which contains high ZDDP which will poison the catalytic converter.

[@gregorymalchuk272]

The only difference with high mileage oil is the presence of seal swell agents which help with leaking crankshaft seals and hard valve stem seals. They don't have any more ZDDP or they wouldn't meet the latest API SP oil specification.

[@gregorymalchuk272]

The sound is pinging caused by oil droplets getting into the combustion chamber, lowering the effective octane rating of the mixture in the combustion chamber, and and causing the pinging. Try some of these new cleaning oils from Valvolene or Castrol. And try going up a viscosity grade to somethingW-30. If you don't, the catalyst will eventually fail.

[@shogun666hit]

So listen up Prius owners: all the problems on Prius engines come from EGR clogging up and bad placement of PCV valve. PCV valve placement can be circumvented by installing a catch can sistem and reposition the PCV valve (there are videos on KZbin). Installing a catch can sistem like that will do wonders for the EGR and intake manifold clogging and minimize oil consumption. If engines starts knocking on cold starts u will soon get the EGR engine light. A full cleaning of the EGR sistem and intake manifold ( maybe replacement of the EGR valve will be required) if u keep using the car with these issues the head gasket will fail.

[@EvzenKovar-i5p]

It is also incredibly important to change your coolant. Nowhere in my service schedule, that Toyota gave me in 2012, does it recommend a coolant service. The maintenance schedule book goes out to 120K miles with no coolant change or transmission service. Coolant becomes acidic with age and will eat at the black material on the MLS head gasket.

[@jasondominguez8434]

Completely clean the Egr system & intake manifold, Add a high quality oil catch can & the oil burning will stop, Atleast it did for me .

[@julioaguirre44]

I was thinking of a catch can so it doesn't fill the intake. Thanks for this information. My guess thats what he is having the engine seeping into the intake and thats why he gets that pinging sound

[@riannilsen5725]

Where’s the video you mentioned in the very beginning of this video? I just subscribed but can’t seem to find it anywhere 😕

[@jafinch78]

I'm debating running Amsoil through for an oil change or three to see if that helps clean up. Looks like best to order the gallon jugs online and join their program. Walmart has the 20K Mobile 1 jugs for a better price. I like the Toyota dealerships for filters if I'm doing myself. I'm at ~260K and maybe the last 15-20K I've been noticing. Time to change the PCV Valve and maybe clean the EGR circuit and Intake circuit. Might have the lower ring stuck too and maybe some sort of oil cleaner treatment alone might help... though wondering about using the Amsoil for a few to see if that alone helps. Thanks for sharing.

[@jafinch78]

I've always had dealership do my oil changes for the most part... and I thought was no big deal they'd get up to half typically. Now that I've been having to top, I make certain is at the full mark when I do add or change from now on. Yes, same noise issue and that's a low oil indicator when starting up and makes more that cold weather second or so scary death like rattle. I notice mine makes that noise like you're describing more when the battery is low and seemed more when on hot days and running the AC as well... though might be related to low battery. I don't notice when my oil is topped off. Mine is a 2013 Prius 2.

[@sueellenmcgoey8708]

Great tips! I use marvel mystery oil 4 ounces every fill up And 2 ounces in oil last 500 miles before oil change Boosts my mpg from 44-45 to 48-50 Used MMO last 20 years in all my engines Zero turns as well

[@mr.revealing1455]

Wow, that's a substantial boost! I'll have to look into it as that is the first time I've heard of it. Thank you!

[@rondhole]

​@@mr.revealing1455the oil pressure is too low. Either low on oil or the timing chain tensioner gets weaker

[@pjanoo6973]

I don't do any of that and still get 48 average mpg. It's all in the technique of how you drive

[@sueellenmcgoey8708]

@@pjanoo6973 I have gotten 52-62 mpg on occasion and unless I use MMO it stays at 48mpg. So keeping it clean definitely helps. I do the pulse and glide as well

[@realsocialmedialeads473]

I had to add oil yesterday when it was only 1,000 miles since my last oil change!

[@camposvazquez]

You will not be able to eliminate oil burning but you definitely can decrease it Mmo for oil flushes 500-1000 before oil change Use synthetic oil Allow engine to properly warm up in cold starts Keep rpms low by observing posted speed limits Keep rpms low when traveling up inclines Do oil interval changes at 5000 miles

[@gregorymalchuk272]

Try the Valvolene R&P oil or Castrol Ultraclean oil. And if that doesn't yield enough results, try raising the oil viscosity. You have an incentive to try to do something, because it will eventually destroy the catalytic converter which is expensive to replace.

[@jtuazonhere]

I have a 2011 with 260k miles. Started burning oil around 220k. Just been topping it off. I had an 2007 honda accord that was burning oil as well and it was pretty. Much the same problem, stuck rings. On the accord forum they recommended auto-rx oil additive. It worked for for accord. 3 months ago I tried it on the prius. 1 bottle after oil change. It did NOT burn any oil during that cycle. In very cautious and don't easily believe in snake oils, specially for cars, but auto-rx worked.

[@broletsdiginasmr5366]

Maybe PCV valve is shot. Change it. My 2015 Prius 125,000 miles not yet burning.

[@Hallahanify]

Ive heard not to fill it up to the top of the dipstick. Keep it haleay between low and full. I think if you put too much in it leaks more and clogs up the egr

[@teo-X3]

hello friend of prius, I bring you my experience with a xw30 year 09, 170k km and no oil consumption. I have seen many American videos on the problems of the prius (head gaskets, oil consumption etc) and I think it is due to the different driving styles we have in the old continent, here in Italy it is difficult to find a prius with problems, the (frivolous) people change to have the latest model😂

[@benc1927]

Your model year does not have the oil consumption problem.

Just change the pistons ring and clean up the EGR.

[@rondhole]

The 2015 up Prius and Prius V is not oil burner if the owner maintain it well. 5k miles/6 months not 10k miles. The 10k miles is eligible only if we do 80% highway and 16 miles minimum each trip. The 2010-2012 has defective piston rings design. Unfortunately, 1L per 1000k miles is cons ider normal

[@sueellenmcgoey8708]

The egr is prone to carbon clogging which can cause blown head gaskets. Costco has best gas Along with shell, Texaco and chevron. Mobile one. Hence the use of MMO and top tier gas with detergents.

[@mr.revealing1455]

Yes, I only use Costco and Mobil. The most important thing I hear about gas is to make sure it is "Top Tier" gas. If you google "Top Tier Gas" you will get a list of all the brands that have the Top Tier additives that help clean things out and keep them clean. Costco is the only wholesale club gas that is Top Tier.... Sam's Club and BJ's Wholesale Club gas stations are not Top Tier. We will talk more in future videos about the EGR and Head Gaskets!

[@paladain55]

That noise you hear and feel is probably pinging. Its caused by the lack of egr condition from the egr system clogging. Log into something prius related on a forum or facebook and figure out how to clean the egr system and replace the plugs and pcv valve. I bet you are very close to losing a head gasket.

[@blendiflamuraj7220]

The valves are doing that noise. Clean the valves,and use the 93 octane gas.

[@sueellenmcgoey8708]

I change mine every 5000 miles. As oil breaks down too much at 10k

[@mr.revealing1455]

Yes, I would agree that is the way to go especially if you have high mileage and notice the oil burning as fast as mine is.

[@ericberger3209]

U got to change the pcv valve... and it's time to change the head gasket... u- tube (gasketmasters) & your welcome.

[@syedrafay8480]

If it's burning and it's high mileage why don't you try high mileage oil from any where. I tried I my 2014 camary hybrid it stop burning after continues use of high mileage oil I think it performs well with old or high mileage piston rings.

[@mr.revealing1455]

That's good to hear, that would be sweet if it works for me. I will probably be switching to high mileage oil on my vehicles that do have high mileage!

[@rondhole]

​@mr.revealing1455 do endoscopy and check the condition of the cylinder wall. 2015 and newer on mine does not burn a bit of oil at 210k miles. I started to change oil every 5k miles/6 months at around 60k miles.
