    But the thing is, YOU don't have this issue. There are many owners that experience hv battery failure, you want to worry about that while you don't have this problem either?

    The longer OCI might have something to do with it, but there's no proof on that. If you want to be proactive about this issue, you can start changing your oil at 5000 mile OCI vs 10000 miles OCI

    I don't have the issue perhaps because my car doesn't yet have the mileage of those that do, typically. I don't want to have the issue later, so I'd like to know what's at the bottom of it. So far, we're only speculating. Oil change intervals might not even be a significant factor, as you said yourself.

    Somebody should be finding out what Prii with that problem have in common in their maintenance history, and in their owners' other relevant habits.

    Well I would like to appoint you with finding out, since you are so proactive on this subject. I hate how my 2010 keeps burning oil

    i don't think that's important anymore. modern engines don't require extended break in as the parts are precision made with polished surfaces at the factory. by the time the car leaves the factory, 90% of break-in is done.

    besides, if break in was the problem here, oil consumption would persist from the beginning.

    Let's say there's some contaminants in the engine/oil, mixed with super heavy footed driving during the break in period, wouldn't that cause damage? Toyota does have a 600 mile break in period in their manual.

    im not sure if its been mentioned or not but the pcv valve is a likely suspect..i know my gen 2 was burning just over a qt between changes and less than half after I changed the pcv valve.it cost 6 bucks on e bay.if the car isn't smoking you can rule out rings most of the time

    For the record:
    83,000 miles
    10K OCI (do it myself)
    Due for oil change within the next 2K miles.
    Just checked the dipstick yesterday - Still at the FULL mark

    sorry for not sugar coating, but this is a complete BS and has been since they started using cat convertors.

    did you vote for the record?

    RE: my 2004 caravan blew smoke from bad rings and valve guides seals and it had a cat.

    because when the oil consumption exceeds 1qt/500 miles or so, it kills/overwhelms the cat converter.

    I have a 2011 built in 2010 and its got 127k on it, it uses 4 quarts in 10k miles more when its hot. Dealer swears its normal, my 7.3 ford diesel truck that makes 400hp 700lbs Tq uses less than one qt every 10k I call BS on Toyota. they say 1qt per thousand miles is acceptable. im down to 35 mpg and they still say its ok.

    I believe the one quart per thousand miles is an Industry standard or maybe a Toyota general standard. While one quart every thousand miles might be "acceptable", it's definitely not "normal."

    I was thinking that Toyota's definition of 'excessive oil use' was a bit more than 1q/1000 miles.

    Unless you never want to check under the hood between oil changes (which isn't too bright if your oil change interval is once every six months), adding oil when needed isn't a major headache. Unless, of course, you're really burning it and needing to add weekly or daily - which I've never experienced with the 25 or so cars I've owned since 1976.

    My 05 has been using a qt every 3000 miles for the last 75K miles. I top it off every 1000 miles until 4000 miles and don't add any again until I change the oil at 5000 miles. The Prius only cost me $7K when I bought it nearly five years ago when it had 134K miles. I'd say I've gotten my money's worth and then some. The question now is how much longer will it last before the HV battery dies. Hopefully not until the odometer freezes at 299999.

    yah, if your car consumes more than 1L of oil per 1000km, contact your dealer, so they can sell you a new $5000 engine, LOL.
