How much oil does your car burn?
I got a 2011 cruze eco 1.4t, and did about 8-9k on my oil.
The indicator said I still had 22% of oil left to go, but it was well beyond the 6-7k I usually change the (Semi-synthetic, non-dexos) oil.
I usually change it when the engine starts vibrating on idle with the AC on.
But as you may know, Hurricane Irma had visited us in the past month, so I surpassed this with 1-2k miles.
When I checked, the oil levels were below the lowest marker, however, the bottom end of the dipstick still had some on it, so I added on average about 1/4th to 1/2 of a quart of oil, before I went and did an oil change.
How much is the car supposed to burn?
I hear Turbo engines always burn oil?
Just want to know, because I'm planning on topping off the oil, every X- miles (say, halfway between oil changes, or so).
I have used Mobil 1 Synthetic Motor Oil, the grey/silver label, which is Dexos 1 compliant, semi synthetic oil, and it works really, really well!
Since the price of the Dexos oil ($22/5Quart) is only 10% higher than semi synthetic($20/5Quart), and semi synthetic is 10% higher than dino juice(<$15/5qt), I decided to stick with Dexos; mainly because the Dexos oil lasts me almost 10k miles before the engine starts vibrating at idle.
Regular Semi-synthetic lasts about 6k Miles, and dino juice lasts surprisingly... almost nothing..
I had my oil change done, with Dino, and the car ran fine for about a month or two (1-2k miles), before it was in a worse state, than with the 6k miles semi-synthetic that was in before!
I haven't tried full synthetic yet, but Mobil 1 has 'full synthetic' labels, on semi synthetic oil, which is really deceptive!
Their green labeled oil is actually a mix of full, and semi synthetic, but is really good.
Their grey labels, are Dexos compliant, and awesome oil as well!
They do smell really funny, as in, you know there are chemicals in there, that aren't found in dino juice!
The only other oil that really is full synthetic from Mobil 1, will be their yellow/gold label, but that one goes for $37/5quarts, and is a bit out of my reach!

Oil consumption, on the order of one quart per 1000 miles, is actually considered normal/acceptable usage for any gasoline powered vehicle.
You will have folks that report no consumption between oil changes, and then hear from others that experience their same make/same powertrain, similar mileage vehicle consume a quart every X miles.
There are many reasons for the variable experiences.
Although built on a assembly line, using the same parts and procedures, there are variables along the lines of piston ring gaps, for example....not always the same, but fall into the plus/minus range allowed for production. This variable applies to all engine components.
This explains why one engine consumes oil and the one that came off the line uses no measurable oil once broken in.
Driving style also comes into play.......an engine that experiences a great deal of high rpm operation has a better than average chance of consuming oil, but again, not always, likely due to the same variables.
A great deal of short trips can be a fooler too.
Short trips tend to create internal condensation......replacing oil consumed with water. The oil holds the condensation in suspension so you don't see a color change.....everything looks normal. Those short trips are adding unburned fuel from the rich condition of startup to the oil as well, thinning it and making it more prone to get past the rings and seals and be burned.
That same car, showing full on the dipstick after, say, 3000 miles, is now taken on a several hundred mile road trip at high speed.
The oil, with the mix of moisture and fuel, now operating a full temperature, boils off the accumulated moisture, lowering the level, and the remaining oil, thinned with fuel and sneaking past seals and rings, obviously lowering it further.
When you check the oil after the trip, you a find a quart consumed over only, say, 600 miles in this example.
Naturally, the first thought is something is wrong, when, in fact, nothing requires attention beyond a fresh oil change.
In most cases, engine disassembly and measurements will show everything within specification.......hence the '1 quart per 1000 miles' industry standard.

I go 15,000 miles between changes on AMSOIL Signature Series and my car does not burn any measurable or noticeable amount of oil between those 15,000 mile intervals. The oil is still at the top of the dipstick. Here's what my dipstick looked like after 10,500 miles recently.

Running a 1.4T that long, on syn blend oil, and running it more than a quart low... I hope you enjoy spending money on your car - on repairs.
Turbo cars can lose some oil through the turbo with no harm (unless you don't check it) but "turbo cars burn oil" is false.
I run Valvoline Synpower at 5K intervals and at 104K have had the level on the dipstick move about 1/2 of one of the graduations on the dipstick, one time. That was probably due to the spirited 10 mile? backroad jaunt I took that had the brakes smoking when I got to my destination. Otherwise the oil level never moves.

?? wait, what??..snipped..
I usually change it when the engine starts vibrating on idle with the AC on.
....snipped
The engine is running super smooth, no vibrations on idle, until the oil starts getting bad.?? wait, what??
Then, with the AC on, it idles a little tougher, and I feel it vibrating gently.
That's my indication of an oil change.
I think as far as a quart on oil every 1k miles is a lot of oil! Your engine will run dry in 5k miles.
A quart on 10k miles sound a lot even.
I'm at about half a quart, at 10k miles. They filled up my car at around halfway the dipstick, not full.
Don't take this the wrong way (sometimes difficult to convey the way things are said via text on a screenThe engine is running super smooth, no vibrations on idle, until the oil starts getting bad.

) but why wait until that happens?? Akin to waiting until your engine can't breathe to change the air filter, or waiting until you see steel in the tire treads to change tires...follow?
Just change it every 5k or so....
I mean, if you wait until your engine starts to show signs of possible excessive wear (running rough on idle) to change the oil, it's no wonder why you are burning oil.
And fwiw, in answer to your original question, I have 120k on my 2012 1.4l, change the oil every 3-4k, and never lose a drop. I ignore the OLM (useless imo, but then again, I'm old school
)
That seems reasonable, but not a good measure for oil changes, the reliability of popping the hood and checking the dipstick, when the car is warm and off, and how much time is required to do so make it the best way of checking your oil.The engine is running super smooth, no vibrations on idle, until the oil starts getting bad.

my Cruze runs an average of 3k miles a year, with and average of 50 mile trips once a mon minimum to keep her exercised and then road trips in the summer, she won't run from November to march.my car isn't even run hard when it is run, so I shouldn't be burning oil, but a car which has been neglected and beaten will most definitely burn some measurable amount of oil
This is correct and helpful, I have heard this in other forums, Subaru and Mazda has it in their owners manuals too, it's true that it's "acceptable" and sometimes the norm for those cars (which run 0w-20) my wife's Mazda sees a lot of driving a lot of city and a fair amount of highway, maybe 65/35 and urns about 1/2 qt of oil. My brothers Subaru Outback runs 0w-20 and burns 1 qt, My pickemup truck burns a quart after 3000 miles at 195k on the odo with 5w-20 high mileage and Lucas Molasses in it. Burnt maybe 1.5-2 quarts without the molasses lolOil consumption, on the order of one quart per 1000 miles, is actually considered normal/acceptable usage for any gasoline powered vehicle.

One should, once the car is broken in, be able to understand their cars' norm. but when someone's car, after a life of no oil consumption, without changing variables such a as driving habits or oil used in change, starts burning oil between changes, would be an indicator of wear in rings and seals and deterioration of the internal pistons, even wear of combustion chamber/head allowing oil to pass into he mix

You really should not be running the OEM oil for longer than 5k mile intervals and 1 year, whichever comes first.

Once I changed it, I put my own synthetic oil in it.
I've noticed that the engine starts acting up a little after 7k miles (though the oil gauge still says ~22%); but Dexos oil seems to last a little longer.
When I went to the dealership he said to change it around this percentage; though if I go any further, I find it will start sounding and vibrating more and more like an old diesel engine.
I also go 15,000 miles on Amsoil SS and experience no loss of oil. I'm at almost 14,000 miles and the dipstick reads full.
If an engine uses a qt per 1000 miles I would be thinking it's time for an engine rebuild. My old 3.8 Commodore used 500ml (just under a pint) in 10,000km (6,000 miles) exactly as the owners manual said it should. It was still doing this when I sold it at 250,000km. Oil was changed every 10,000km. My Cruze is a diesel and in 5 years has not used any measurable oil. Service is every 9 months with Dexos II full synthetic oil, with a new filter of course. Car only has 58,000km on the clock and has never had any engine problems.
My 2015 LUV goes through about 1 quart every 1000 miles. I get to choose whether it gets sucked through the crappily designed PCV or, If I block off the PCV and just use a breather, it comes out of the low-friction-but-needs-vacuum-to-stay-sealed front main seal. True story! Fun stuff to be sure.
Neither of my Cruzes has used oil in between changes with the exception of when the PCV intake manifold check valve went missing on the 2012. Then it made noticeable blue smoke out the exhaust and was down ~1/2 qt of oil in 1000 miles.
This is how my 1.4L/ 6 spd is. I only added a little when I changed the filter @7500 of 15K. I will be running 18K intervals this current change.I also go 15,000 miles on Amsoil SS and experience no loss of oil. I'm at almost 14,000 miles and the dipstick reads full.
I've read that it's "acceptable" to burn up to a qt in between 5000 mile intervals of a subaru (outback specifically) or mazda (2.0-2.5 skyactive engines) that both run 0w-20 oil, not necessarily that ALL normally do, but that it can be acceptable for some to, like Rob said, on an assembly lime, there can't be the specific care/consistency, and a reaction such as oil consumption relys on so many variables that many off the same line will have different amounts of specifications in the way they run
My cruze won't burn a droo, I drive lightly, shorter trips more often than not, and almost always in favorable driving condotions, my pickemup, 04 4.0 ranger with 200k on the odo burns a full quart in between 3k mile hoghmileage synthetic blend oil changes with a quart of oil stabilizer (molasses) so in that case it's age/mileage/abuse related, so care is clearly a variable aswell

We are talking Cruzes here, my diesel doesn’t use any noticeable oil during 7000-7500 mile changes. I drive a lot so sometimes it’s just a few weeks. I think all of this discussion is car specific. If I was using 1 qt every 1000 miles on a newer car I would be finding out why, leaks, or burning, etc. on a cruze with a smaller oil capacity to begin with I would be concerned. If I was driving a truck and used a quart out of 8 I might not be as concerned but still would want to know why. I rarely have ever owned a car that used oil in a big way.
I noticed the other day that my cruze used about half a quart in 2000 miles. However, I drive very spirited and I'm running a bnr tune. I also have the XR PCV fix kit installed. Has anyone noticed oil consumption after installing the kit?
I think we're talking about 2 distinct beasts here.
An engine in principle, should burn less than 1oz of oil between oil changes; simply because it burns more, but crud, water, carbon and other stuff starts accumulating in the oil, making it appear that you've really only burned an oz.
This should be the case of most gasoline and diesel 4 stroke engines.
The cruze I am talking about, is the turbo version.
Turbos are known to consume something. not much, but something.
They get really really hot, and rotate at really high RPMs. Much hotter than the oil can handle.
Which is why some of the oil vaporizes, or burns, within the turbo housing; and why Chevrolet recommends Dexos oil to be used, due to it's higher resistance to high temperatures.
The Outback you are talking about, uses a Porsche boxer engine.
They're great cars, but the low oil viscosity, and horizontally stacked cylinders make that it uses up a lot more oil than any other engine (4 or 6 cylinders are usually pointed upwards, either in an inline, or V-shaped way.
