1.2 DIG-T - Oil loss
Posted: Wed Jun 10, 2015 8:42 pm
My 1.2 DIgi T is loosing oil fast, very worrying . Had its 1st service 20th April checked oil level when I got home as I had suspicions prior to service something was not right., level was near to max . Have done less than 900 miles and oil level is just at the minimum level , there is no visible loss of oil under the car ,no clouds of blue smoke from the exhaust, engine seems to be running ok .Local dealer has told me to top it up and bring vehicle in on 19th June , to have oil drained and a measured amount of oil put in so it can be monitored over a period.I would have thought that the service date and mileage coved since 20th April would have been enough evidence for the dealership to say bring it in immediately .ANY THOUGHTS OR COMMENTS.

For those first time reading this thread, there is a lot of information. The problem boils down to the following:
1. Poor build quality.
Nissan have admitted that a number of engines have incorrectly sized pistons (read: smaller pistons within larger bores rather than them being matched perfectly). This can cause oil loss of varying degrees. Some engines are being replaced due to this.
It appears that some dealers are testing engines via a compression test of some sort to identify a fault.
2. Bad engine mapping
It has been confirmed from Nissan that there is a new engine map available which can prevent loss of oil. It is unknown if this affects all engines, or specific range (see above). Currently unconfirmed reports that Nissan have altered the engine mapping to increase inlet manifold pressure at low speed/low power requirements which may prevent oil loss through the piston rings. I (SplanK) am awaiting information from my dealer regarding this issue.
It is believed that the theory of the suggestion that Nissan are going to lower the oil pressure is incorrect.
