[W126 Coupe] don't use high mileage oils

[Shayegan, Richard]

Well, I did ground it when I changed the oil. The time I didn't ground
it I wasn't trying to get the pressure up, I just forgot to reattach it.
I guess I didn't notice any foul since I realized my folly on the first
crank of like 3 seconds. As far as the mechanic, they do what we've done
for the last 16 years (my dad took it to the dealer while it was under
warranty cause you never know what they'll say you did to void your
warranty): close the plug, stick in the filter, close the filter top,
fill it up with oil, start the car, and wait for the pressure to build
(takes like 4-5 seconds). Though you know, this would explain our 60k
mile timing chain change intervals.

If you operate the starter with the coil wire to distributor tower
disconnected for any length of time WITHOUT the coil wire grounded you
can
destroy the coil and or ignition module.  Another point is it typically
takes 3-5 cycles at 5 seconds or so of cranking each to show some level
of
oil pressure on the dash gauge.  I mention the short starter cycles here
as
well where it is a good idea to give the starter a few seconds between
cranks to cool down a bit.  So, next time ground the coil wire before
cranking the engine over and limit the starter time to 5 seconds or so
to
preserve the life of the starter.

These are just my methods as a DIY'r Richard.  If I have left the 380 to
sit
for a week or more (most often during the winter) I always ground the
coil
and run the starter until I see the pressure needle move after several
cycles.  So, if you feel uncomfortable watch your mechanic next time the
oil
is changed on the 380 to see how he does this without damaging the
timing
chain and or rails where the chain tensioner always loses pressure after
an
oil change.
