BMW X3 2.5si M series. High Oil Consumption

In the great plan of things simply claiming excessive oil consumption is not enough. You think you know what you mean but how much is excessive?

Car manufacturers insist before taking any warranty action for excessive oil consumption a test must be carried out to decide whether the consumption is excessive and whether repair will be economic. Even though your car isn't under warranty the principle generally will be the same.

An oil consumption test is carried out after a few basic checks and means topping up the oil exactly and then driving 750 miles of mixed town and country driving that doesn't include any sustained high speeds or heavy congested traffic. The oil is then checked and topped up exactly and if the quantity is less than 1 litre it is considered acceptable due to any improvement being uneconomic to achieve.

How many miles is your car covering per litre?

Of course if the engine is producing smoke things are somewhat different...

did u get the car fixed?

oil sep not causing this issue,this would be caused by the crankcase valve both on 6 and 8 cyl,if you have a 6 the part is locaed below the intake behind the throttle,you must also remove the dip stick and clean out the drain on the stick,if you have a 8 cyl than you must rere the intake and repl the rear cover and oil drain, also this issue is more commonly found when temps are very cold.either way this should be replace to prevent furhter damages to the enigine.this should solve the oil consumption issue as long as there are no other leaks present

4.25 litres.Grade ow/30,ow/40.

if there no leaks , now those older excels had problems with the rear main seals leaking with high milage, but you will see it under the car. also bad valve seals will cause a large oil consumption issue,but often you will see blue/ white smoke out the tailpipe esp on start up.

your going to have to clean it down good with some engine cleaner, then run engine, try to pin down leak. may have a bad oil preasure switch thats leaking, or oil filter, or a gasket; hope this helps good luck.

oil consumption is normal on BMW's especially if you drive the car hard and especially if it is still cold.

2001 up to 2003 for shure don't know about any other models, where i found this it said 2001 to current but not shure when it was posted. Thanks

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!
