I have 3800km or 2361miles on my 370 and it has not lost any oil, including during breakin. I did not baby the car during break in

Same here! But for what ever reason, this car is different when it comes to checking the oil!:tiphat:


Page 285 of the owners manual.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick again and check the oil
level. It should be within the range*1 . If the
oil level is below*2 , remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill*3 .
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the breakin
period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insufficient
amount of oil can damage the
engine, and such damage is not covered
by warranty.

Makes you wonder who's writing their manuals. "Run engine to suck the oil out of the oil pan, then let it sit long enough so the oil runs back into the oil pan so you can check the level." Bizarre. :icon14:

Makes you wonder why you didn't read the manual before jumping on one of those who did. :tiphat:

Is that a piston ring problem? Head gasket issue? If so, it shouldn't be difficult for Nissan to pinpoint and correct it. Cheers.
