[W126 Coupe] don't use high mileage oils

[Dick Spellman]

Richard:

The Benz filters are just fine.  I pay just under $6 for the Mann filters.
I have never checked on the dealer pricing.  Mann comes with the gasket on
the filter housing and the 13mm drain plug gasket as well.  Please let me
know what MB is charging just so I'll know and if it comes with the same
components.

On your 380 engine when you drain the oil and replace the filter the
tensioner will loose oil.  With no oil you have little or no pressure on the
chain tensioner.  By using just the starter to rotate the engine you do not
get the kick of the engine igniting and this reduces the possible damage
caused by chain slap with a loose tensioner.

You should absolutely ground the coil wire.  Just pull the dist cap coil
wire and jumper to ground.  Then crank for 5 seconds and let rest and repeat
(usually 4-6 times) just until you see the oil pressure needle rise a bit.
Plug the coil wire back on to the dist. cap and let the engine catch.  Stop
the engine after a minute or so.  Recheck your oil level and top it off.
That's it.
