1.9 DCi - Consuming oil at a rate of 250ml per 5000 miles
Posted: Wed Feb 04, 2009 12:34 pm
I’m hoping that someone on this forum might be able to help me with a concern I have with my 55 plate Megane Scenic 1.9 DCI which has done 56,000 miles… I have had the car from new.
The old girl has started to consume oil at the rate of about 250 ml per 5000 miles.
There is no oil leaking from the engine, so I am assuming that the oil is be burned due to the lack of physical evidence.
I have the oil changed every 10,000 miles and always use fully synthetic oil from a reputable manufacturer.
Some observations that I have noticed is that if I accelerate really hard from a junction there is quite a lot of smoke if I have been cruising or driving in traffic for a period of time.
When I start up there is no cloud of smoke.
When I check the oil using the dip-stick I have noticed that there is oil pooling on the engine stop device, indicating that oil is getting in to the induction side of the manifold.
The car is performing as well as she has always done – lots of poke, and good fuel consumption (48 MPG typically). There is no smoke if the car is driven hard except the initial burst after leaving a built up area.
Any ideas how the oil might be getting in to the induction side of the system?
Is this normal for this engine type – (after all 250 ml oil per 5000 miles is not a huge loss)?
Am I worrying unnecessarily?
Not knowing diesel engines all that well, I am guessing that the oil is coming from the turbo oil seals. This engine has always had to be topped up between oil changes, but the rate of consumption has defiantly increased over the last 10 months.
Thanks in advance for any hints or suggestions…
