    Update: 2 more quarts since I first posted this thread. Oil is still super clean after 4k miles since last change. Fluffy black carbon in the tailpipe. I'm flummoxed - how can the oil still be clean?

    There's an engine/transmission combo with 100k miles on Ebay for $1450. There are lots of used engines available around $1500. That might be the best solution.

    That was July 8th? So to the 13th? How many miles?

    You're using more oil than a two-stroke. :eek:

    Disappointed in Toyota. My dad and I replaced the engine in my sisters 2010 Prius due to extreme oil consumption, and eventually head gasket failure. She bought a used engine from a plug-in Prius with 40,000 miles on the engine. In reality I'm sure it had less miles than that since it was a plug in. She bought it for $1000

    Could it be that you are adding clean oil?

    I think it's running out to fast to get dirty. Maybe you could just pop a new filter on once in a while, start using a thicker and cheaper oil and roll with it.

    why would you want someones worn motor they are going to have the same problems as yours. look around google for Toyota oil consumption..( not prius), I saw something about defective rings maybe maybe its the same suppliers 2010's, my 08 uses little oil at 160000 miles

    You bought a car hoping for 400k miles, really.... and you drive it at 85 miles per hour....

    84 mph is a regular cruising speed for Wyoming and Montana. If it wasn't designed to run all day at 84, it isn't a good car for the wide open areas of the country.

    How long since you've put in the 40k engine? Are you glad that you did it? I'll have an official diagnosis from Toyota next week then I'll have more direction on what to do.

    The regular high speed driving could easily be a contributor to the problem. 172k miles - Probably 130k of that is at 84 mph.

    I think the car should handle highway driving. If not, I'll need to sell mine.

    It's been a month and about 3k miles. Glad we did it. Runs great

    I think it's very important to take extra step to keep the engine running healthy in parts of the country where 80mph speed limits or in the mountain range with miles and miles of uphill. If this is the case, switch to 5w-30 vs 0w-20 can help provide the lubrication and protections the engine calls for in those situations, and I would do it even before the engine starts having drinking problem. It is just my opinion that I would rather suffer a bit in MPG by switching to heavier oil for better protection, after all, it is really expensive to replace an engine, or a car.

    I believe 84 mph is not highway driving anywhere in the US.
    It is speeding!

    sounds like he wants an old used car to preform like it did the day it was new forever, clearly that's not reality so the simple answer is buy a new car every 3 years when they start to show wear and be happy forever.... im shocked he hasn't blown the motor pushing 85 all day long, I would buy a V8 not a 4 cly if your going to abuse it, old cop cars and taxis are cheap

    I find the headline to be disingenuous.
    The OP is far from being ready to scrap this vehicle.

    If I read a headline that say's "Ready To Scrap It"...then I want pictures, maybe even video, of a junkyard and a metal compacter.

    This is just a disappointing in comparison thread about advanced oil usage.

    Slap a new engine in, or just keep pouring the oil in...and that vehicle could go another 170,000 miles.
    Retire it to the back pasture of local city driving?

    I want a wrecking ball and twisted metal, and a viral video of Prius Destruction!

    The posted limit is 80, add 5% for speedometer error and you end up with 84!

    You could drive 80. Or a bit slower. (n)

    Took it to Toyota for a diagnosis today. They changed the oil, sealed all the openings, and told me to come back in 1200 miles. I caught a glance of the pre-diagnosis sheet that mentioned pistons and rings. It did not mentioned valve guides or PCV. I expect to bring it to the dealer at 400 and 800 miles for them to top-off the oil. I'm not to touch anything under the hood.

    If their answer is "pistons and rings" and big $$$ to repair, I'll have someone else put a used engine in it.

    I'll update this thread in 1200 miles.
