oil consumption on GL 320 CDI 2008
I do love the diesel!
STP
if you remove the intake on any turbo diesel engine you will find that it is always wet, sludged-up a bit. this is from the blow-by. the oil enters the turbo to cool it off and if the turbo is not spinning hard enough it will seep through the bearings and will find its way into the manifold. on the diesel vw cars the oil also leaks outside of the turbo.
if bad enough (worn out turbo) you get the dreaded "run-away" diesel engine - a condition where (especially on automatic tranny vehicle) the engine races at redline and over and cannot be stopped even if you turn off the ignition because the engine is feeding on blown-by engine oil by the turbo. lots of smoke and destroyed engine is usually the result.
consuming some oil in the gl320 is normal.
