[W126 Coupe]gung hey fat choy

I vote for number 1. The SEC M117 engine has a known deficiency in that if
you run it at very high revs, the right side valve cover gallery ends up
pretty much full of oil and starves the engine a bit in that condition. It's
temporary and slowing down lets the oil drain back down. If you added oil
and it afterward NEVER showed over-full, then it was never there. I believe
that you were a victim of the dealers recto-cranial inversion (head up
arse). One good point is that the 560 engine is an 8-quart/liter system and
the low oil light comes on at 2 quarts/liters down. You still had lots of
oil in there if you drove it at all without the light on and it came on
later. How much oil did you have to add to the engine when "filling" it?

  Hope the football fans enjoyed the Superbowl.

  OK guys this has been puzzling me for years.

  Got the oil changed at a dealer and over the next several days travelled
about 1000km (620miles).  Lifted the right foot to enter a small town and
the oil light came on, engine making distressed sounds.  Luckily there was a
service station nearby.  No oil on the dipstick.  Filled the engine,
restarted the car and drove another thousand kilometres, checking the oil at
every stop.  Consumption was low - normal.  Kept the car a few years more
and it never did it again.

  Only thing I can think of is 1.  Not enough oil put in at the change.  2.
Wrong grade of oil used.

  Your opinions?
