Prius (Gen 3) :: Excessive Oil Consumption Significantly Worse In 2010 Model?
May 23, 2015
I'm in the market for a Prius and I read on carcomplaints that the 2010 model has excessive oil consumption issues. When I searched for more info about this issue, it seems that it occurs in the other model years as well. I'm wondering if I should avoid the 2010 model when looking for a used Prius, or if the trend on carcomplaints is incorrect and this issue is no worse on this model year than others. Did Toyota switch to a different piston ring in this year or are they all the same in the gen 3s?

Prius start consuming excessive engine oil.

What is considered to be excessive oil consumption in regards to the TSB issued by Toyota for the 2.4L engine. Mine is using 2+ quarts per 5000 mile interval. It isn't leaking, so it has to be burning it somehow. It doesn't smoke visibly, but that is a lot of oil IMO (my Harley doesn't use nearly as much).

I have an old (fourth generation before 2005) and low performance bmw 316 at its 40 000 km (its been in garage for some time after it's done 19 000, then i bought it, so everything rubbery is problematic), i feel like it burns more fuel then it should considering its performance , since its almost 20 sec. from .naught to 60 , it has a more noticeable engine braking compared to my 2005 passat 1.6 (almost twice as effective), and a higher fuel consumption, when i stop the engine when idling, the rpm needle (or whatever it is, not a native speaker) drops to 0 immediately like in a millisecond or so.. no inertia no nothing, oil and everything is regularly checked up but i think there is something deeper going on.

I bought this car off the showroom floor with about 1,200 miles on it. Since just past 70,000 miles or so, this car has been using more and more oil between changes. It now appears to be up to about 1 quart per thousand miles, maybe just 800 miles. I don't see any sign of a leak. There now are 201,000 miles on this engine. The V-tech solenoid had to be replaced about 30,000 miles back. Timing chain has never been replaced; nothing else major has been repaired. Last new PCV valve was put in about 30,000 miles back. It didn't seem to slow down oil consumption. This oil problem is the only problem with this car, except for the V-tec before, and some rattles. Otherwise it is as reliable as any car I've ever owned, and I've been around a while.
I've read many blogs and other web pages on this, and it's a common problem with this particular Honda engine. Is there any chance that this oil usage is something besides worn piston rings? Some people seem to think it might be worn valve seals, and/or worn camshaft seals? how expensive is that to get fixed? If it's any of these things, is there really any practical solution other than a new engine, or maybe a rebuilt?
Short of thousands of $ in repair costs, would a different type of oil reduce oil consumption? I read some people saying to stay away from synthetic (why would that matter?); some talk about oil treatments; one honda service manager says he puts good old STP in a high mileage, Honda, he owns. I tried that with this car, just one application, and I didn't notice any drop in consumption, but I drive a LOT, in all types of conditions, so I don't know that I gave it a real chance to work. In such an old engine, if I experiment with these, is there any chance of doing further damage to the engine? For that matter, would switching to 5W-30 or maybe a 10-weight, possibly slow down this excessive oil usage? I really don't want to buy a new car.

So I have 95 1 liter 5 speed, it runs fine and smooth first thing, but once it gets warm it idles rough, poor mpg 33-37 and eats a lot of oil have to say a quart every 300 miles does not leak oil, does not smoke, need new muff and resonater.
Check engine light is not on. can i hook it up to hand held code reader .? 95 is it obd 2?

I have a 2001 Jetta GL 2.0... For the past could of months I have had a mysterious oil problem. I constantly have to put oil in. I have changed it. Always put in the correct amount, right around 4qts. I have changed the head gasket, no leak there anyways and there still isn't a leak. I checked the exhaust and I'm not burning oil. I am completely stumped. What else could be happening to the oil? I just changed my oil about 1200 miles ago and I have already added another 2qts. That is just insane. I have gotten to the point where I am checking my oil every single time I drive to work and back, daily. I do all my own work and have never once noticed any leaks of any type. Something is sneaking by me though.

I have a 1996 Geo Prizm, with about 126K miles. I bought it last May, at around 120,000 miles and had no problems with it until recently, other than some minor issues with the power steering in November. In November, it started making a squeaking or grinding noise whenever I went around a sharp turn. It turned out that the power steering fluid was slightly low, so I added more and that was the end of that problem. But I also found out that the previous owner had put the wrong kind of power steering fluid in. Starting about 2 weeks ago, the car started making a squeaking or squealing noise. There would be no squeaking when I started the car, but then it would start when I turned. It is only audible when the engine is idling, and I'm not sure if it is squealing at other times, too.
I figured it was probably one of the belts, probably the power steering belt. However, I checked it and it seemed to be tight enough and did not appear cracked or glazed. A friend of mine who knows much more about cars than I do also checked the power steering, alternator, and A/C compressor pumps for me, and he said they seemed fine. About the same time the squeaking started, I noticed the car seemed to be burning a lot more fuel than usual. I have filled up the gas tank twice since then. Typically, throughout this winter, the car has gotten 33-36 miles per gallon. But on the last tank, it only got 25 MPG and it got 29 MPG on the tank before that. There has been no change in my driving habits to explain this. The engine also sounds slightly rough when it is idling, almost like a diesel engine, but no louder than the car usually sounds. My friend who checked the belts listened to it when it was idling, and he thought he heard a slight knocking sound, which I heard too.
I noticed no decline in performance: the car accelerates just as quickly as ever, and performs the way it always has. The power steering seems to function just fine, despite the squeaking. I thought that perhaps there was something wrong with the timing belt, and that might explain both the squeaking and the increased fuel burn. But I looked online at a few websites, and it sounds like timing belts usually don't show any symptoms when they are wearing out, they usually just fail without much warning. Also, when I bought the car, the previous owner said the timing belt was replaced at around 90K, so it should be fine for a while. I am at a loss as to what might be wrong with the car. I wonder if the squeaking and the increased fuel burn are caused by the same problem, or if there might be separate problems causing each.

Actually I bought a used Corolla 2002 with 120K which seemed fine and the driving is fine. After I bought it, I just found out that the seller has removed the check engine light. When I read the ODB codes, It shows three codes of 0171, 0420, 0441. Also I have recently found out that the engine burns excessive amount of oil. (about a quarter per 200 miles). Actually the driving of the car is fine and as long as I add oil engine it seems fine.I think all of these errors might be just due to a small problem like a broken valve (since it's not high mileage). It seems that there is no vacuum leak from hoses as well.

Im very happy with the Prius that I have a 2010 V, its loaded with all of the options that were available at the time and I get a true 43 -46 mpg with my driving style and daily commute. The Prius averages more than twice the mileage I was getting with my other cars.
But I stumbled on the Lexus Cth and it seems its a Prius with a Lexus styled body and interior. The Lexus is a more conventional body style and seems to be a little better fit and finish on the interior but at a little less MPG. I tested a 2012 Cth with the F sport package over the weekend nd really liked it.

I am trying to figure out how to turn on this display for the odometer. Surely this wasn't designed to only show avg consumption for trips right?

The oil consumption started around 90-100k miles. My wife mostly drives the car so I just check it and fill it without keeping track of mileage. Last week I had a lot of driving to do so I topped off the oil before starting my trip and put a 5 qt 5-20w bottle in the back. I've been through two liters in 2100 miles! Sheesh - I'm ticked off. I do my own oil changes at least every 10k miles, always use 0-20w or 5-20w full synthetic oil (usually Mobil 1). I replaced the spark plugs at 119k miles per maintenance schedule.
Besides the oil consumption, since 115k miles the engine can get into a mode where it misses a little bit at low power once it is completely warmed up. I have a good code reader and nothing ever shows up. I expected the new spark plugs would fix it, but they didn't change anything about how it runs. It is slowly getting worse. I'm going to wait until a code in the ECU is set before fixing it. It could be an ignition coil. I suspect it is an O2 sensor which causes the AFR to be too lean which makes the mix hard to ignite. Time will tell. It runs fine when cruising at highway speeds.
We bought this 2010 Prius III, not 3, new in October 2010. The only out-of-the-ordinary thing we do is live in northern Wyoming where it can be very cold for a long time. We drive 85 mph for long distances to go shopping and visit friends. The gas mileage is the same as it has always been. It varies between 42 and 50 mpg in the summer and 35 and 45 in the winter.

I was under the impression that when you enable EV mode the car will stay in EV till around 40 mph or something close to it? I can't seem to go above 10 mph without getting a message stating "EV Mode disabled due to excessive speed"? Is this a glitch or can you really only go 10 mph? That seems pointless if that is the case.

This is my first summer in my 2010 Prius. Noticed excessive wind on your face when driving with the driver side window down? I'm guessing it might have to do with the shape of the car. I can drive at freeway speeds in my 02 Civic with the window down but if I'm travelling faster than a crawl in the Prius it becomes really annoying.

Yesterday we were on a 10 hour trip and the engine was acting oddly; when braking, the engine sounded just like the engine brake, but the MPG indicated that it was consuming fuel (engine brake does not consume fuel). When braking, the engine would sound, and the MPG indicator indicates fuel consumption, it would go down to 50, with the heavier braking, like when stopping... then at a certain point it would suddenly stop
It seemed to happen most times but not always. This issue didn't happen before.

Just bought a 2012 Prius Three last Friday. The MFD (upper display) shows an average of about 53 mpg so far, and the corresponding 1 & 5 min bars seem to make sense (we have an 07 TCH so we're reasonably familiar).
But the Display Audio unit (6.1 inch) Car>Consumption graph seems to show 100mpg most of the time/most bars. That can't be right and it looks nothing like the MFD display. What am I missing?
