The i-Drive oil sensor isn't that reliable for min/max, you need to add many times and average out. Older engines 'may' burn a little less with 05w40 LL04 grade fully synthetic oil (where the 40 value is slightly more stable/thicker at high temps). Should really be no worse than 1L/1600km average, if I had 1L/600km and was unable to fix then I'd be using cheaper oil ;) and forget about it. The N52 oil consumption often due to CCV breather malfunction (oil sucked into inlet and burnt), worn bore/piston rings burning oil in cylinders (when extreme you see blue smoke at high RPM) or visible oil leaks or sometimes valve stem leak down (after engine has been significantly overheated and cooked valve stem rubbers can perish).
Thank you for the answear, I think is the CCV, i will replace it and i will made another video to let you guys know if that solved the problem. I don't see any oil leaks. During covid, i've let it parked in the same spot for almost 2 months, not a drip on the parking lot. Also i don't have any blue smoke at high rmp.
I have good result with Xado Revitalizant in motorcycle. But it seems you may get better result fixing piston ring. In here people use vegetable oil (palm oil but absolutely avoid castor oil) to reduce that. Try to use ravenol oil. Their oil have low evaporation loss.
I have same car n52b25 and i use always Liqui Moly Leichtlauf HT 5W-40 and once every 50000 km a bottle of Liqui Moly Cera Tec, 300 ml and at 190k still ok and dont burn oil! I thenk you whill by ok!
@@TheCiprian2002 thanks for the answer. Are you sure your engine was not rebuilt. It s impossible for a N52b25 made before june 2010 to not burn at least 1 liter of oil / 4000 kms
Hello. I also have N52B25A on LPG 290K KM. And I have a 29F4.29F5 error just driving around 2000 rpm. Other times not. Don't know what it can be? I don't know why anymore?
@@darkmagician2730 Yea, same result, i've changed the oil to a thicker one, 5-40, it still loose it. It's because of the valve stem seals, they are cheap, but expensive as f*&k to replace.
You can't solve the high oil consumption by just adding this Motor Protect bottle! You probably need to try the Ceratec additive plus change the motor oil you use. If you use 5W-30 try 5W-40 or 10W-40. 10W-40 should significantly make different along with Ceratec
That is acceptable. I think is the CCV in my case, i will replace it and i will made another video to let you guys know if that solved the problem. Subscribe.

@@robe6069 Hi mate. Did you changed the CCV? Did it solved the crazy oil consumption?
Replace valve seals

I have the same engine, it has 170.000km and burns around 1L per 6000-7000km. Thing here is to change the whole CCV system :)...
hello i have same engine. I have replaced CCV but now oil consumption is 1.5liter per 5000km its normal ?
Hello, in the service manual is about 700-800gr per 1.000km. I think is fine. Those engines are designed to consume oil.
CCV system failure?
Has the engine running noise decreased? Has fuel consumption improved? Didn't it just stop burning fat?
use 10w40 or 10w50 oil...that will slow down the oil burn.
Ai rezolvat cu consumul de ulei ?

5w40 never put on BMW 5w30 is water
go with heavier oil 5w40 and see if that reduces the consumption.
I did yesturday. I will see the results in few hundreds of km.

does that work

That's your piston rings gone believe me
No. It is 3.0L.
Only the 2.5L has oil piston rings failure.
Liqui moly 10w60
That oil is too thick for that engine. Oil pump, oil seals and gaskets will be damaged
Liqui moly 5w40 thank me later
