Noticed my car was using quite a lot of oil.
Car is a 06 revup engine,read some threads that there is a known issue with this engine.
Took car to stealers explained about the oil consumption,there reply was that the 350z engine is bullit proof and they had not had any trouble with oil.
I explained that on the various owners club web sites that there is a known issue with the revup engine.He looked on the Nissan data base of issues none came up with oil consumtion.
So they have filled it up again,added some dye and told me to run it for 500 miles then take it back.
Fingers crossed its nothing major,but if it is its still under warranty.
