Captiva Diesel Oil Consumption?

[geoffro67]

Can anyone tell me if their Diesel is consuming any oil?

I have a SX Captiva diesel which has just had its 15000km service. It has consumed almost three quarters of the level between the high and low mark on the dipstick since taking delivery of the new vehicle in October last year.

There are no external oil leaks and Holden said they would do an oil consumption test if requested.
Does anyone know what an oil consumption test is and how they measure?

On a normal oil consumpion test we normally measure the oil level and record it, then top up the level to full and send the car off for 5000km's, on the cars return the level is measued again and the test sheet is faxed off to holden for processing.
