Engine oill dropping

1 month ago,engine oil level was max but now the level is minimum. Engine oil level is dropping so fast. I got a service 3 time at the bmw . But it happens situation again. What's wrong ?

My car has 101400 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
There are several reasons for an engine oil level to read low between oil changes. It is common for an engine to consume a given amount of oil, and all manufacturers have a tolerance for what they consider normal consumption. According to AllDataPro, BMW has set a tolerance of 1 quart per 750 miles as normal consumption. Also keep in mind, that an engine will tend to use more oil as it ages, and a turbo-charged engine will tend to use more oil, over a naturally-aspirated engine. BMW also mentions that the higher horsepower turbo v8 engines can use as much as 2.5 quarts of oil every 1000 miles. This is due to the fact that the engine oil will also be used to cool and lubricate the turbo-chargers components, and therefore, have more avenues for the oil to be consumed. It is extremely important to use the correct grade, and viscosity, of oil in a turbo-charged engine, also.

– The N54 twin-turbocharged inline-six engine from the E90/E92/E93 M3 is another one of BMW`s best engines. It makes excellent power and is very well-built, making it extremely reliable.
This is not an engine for everyone. With the heaps of performance that it brought, along came many reliability issues. That said, BMW has addressed a lot of these problems with some significant updates, and the units in production today are a lot more reliable than the BMW N63 engines that came before.
BMW, filed in May of 2019, initially stated that N63 V8-powered BMW models including versions of the 5 Series, 6 Series, 7 Series, 8 Series, X5, X6, and X7 were defective because of their engine`s propensity to consume oil between scheduled services.

WEAR & TEAR

Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it`s possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.

It will pass 300K for sure. Just do 5k oil change and all required maintenance.. Many people say that it burns oil after 40k. Chain , tensioner and some parts must be changed after 50k.
The BMW N63 is a twin-turbocharged V8 petrol engine which has been in production from 2008 to present. The N63 is the world`s first production car engine to use a “hot-vee” layout, with the turbochargers located inside the “V” of the engine.
10 years/120,000 miles as determined by the vehicle`s original in-service date.
V-6 engines have improved performance compared to V-8 engines, especially when timing acceleration properly because there`s less tendency to drift to the outer edge. However, you can lose a little bit of the power ceiling with the weight advantage.
Consumer Reports` reliability surveys have also found that manufacturers with a lot of experience building turbocharged engines—Audi, BMW, Porsche—tend to have more reliable powertrains.
The M47 is pretty reliable. Inlet swirl flaps can be an issue so check they`ve been removed and go through the service history with a fine-tooth comb. I`ve had a September 2003 320D and typical issues are the swirl flaps and potential turbocharger failures.
Output for the X6`s turbocharged 3.0-liter inline-six engine is up to 375 horsepower, but the power of the 523-hp 4.4-liter twin-turbocharged V-8 remains the same for this year.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

While driving at a speed of 40 mph all at a sudden the car speed dropped to 10 mph and stopped with solid check engine light
ANSWER : Hello. Warning lights accompanied with stalling can be caused by many things. If the oil is low I would go ahead and top it off to prevent the possibility of engine damage, however, it is unlikely that low oil is what caused the stalling. Stalling is most commonly caused by issues with the ignition, engine management, or fuel systems. If one of the components, such as a major sensor, the fuel pump, or the ignition coil, go out or have an issue they can cause the engine to stall. If the vehicle is no longer starting then it may be possible that there is an issue with the electrical system as well, perhaps a faulty battery or alternator. If the alternator goes out it will eventually drain the battery, which could also cause stalling. Scanning the computer for trouble codes, once the vehicle is started, will likely reveal some insight into what the issue may be. As the possibilities could be many, I would recommend having a professional technician, such as one from YourMechanic, come to your location diagnose what may have caused your vehicle to stall.

Check Engine light on. Would the computer give all error codes in one shot? How do we know the engine’s condition?
ANSWER : Hi there. From the description you have provided, I’m am inclined to agree with your assessment of a used engine being installed in your vehicle. An inspection of the engine, by a qualified technician could determine whether the engine is sound. The Check Engine Light on and having a TPS (throttle position sensor) code does not necessarily mean the sensor is at fault. Circuit tests should be performed to confirm the fault. The likelihood of the ECM (electronic control module/computer) giving you all the codes at once is remote. Other component failures could occur. Address those as they come up. Even though you already made the purchase, I recommend having your vehicle inspected by a certified technician so that you can get a thorough evaluation of the car’s true condition.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.
