[W126 Coupe] Oil change

[Mark - FosterFirst]

Hi Legs ( & Markus ),

 

Sounds logical and I am going to start using synthetic. I have a 1982
380SEC. Any suggestions as to which multi-viscosity grade would be best for
this engine - as it is not a 560SEC. Would there be any difference ?

 

Many thanks,

 

Mark

For Ronny and Other Owners,

I wholeheartedly agree with Markus and his recommendation on the use of
synthetic motor oils in the older classic Mercedes-Benz.   My comments are
based on my experience with the Mobil 1 family of synthetic lubricants,
however, I am sure users of synthetics from other manufacturers such as
Amsoil or Castrol can share similar positive experiences.

 Having  been fortunate enough to own and maintain numerous classic
Mercedes-Benz, including perhaps the finest OEM 1991 560 SEC in the United
States, as well as other high lines, I can attest to the excellent
performance of synthetics in my fleet which spans model years from 1975 to
the present.

 In the case of older vehicles Mobil 1 offers several multi-viscosity grade
oils specifically for higher mileage vehicles ranging from 5W-30 to 10W-40.
Ironically, these oils serve to mitigate problems caused by the use of
conventional motor oils..

 From the ExxonMobil literature: "Mobil 1 can help increase the life of all
engines, even those in older vehicles and/or with high mileage. The extra
cleaners in Mobil 1 can help clear stuck rings to help restore engine
efficiency. In fact, Mobil 1 with SuperSynTM 10W-30 is ideal for these
applications. Keep in mind, however, that Mobil 1 cannot correct an existing
engine problem."

 "As your engine ages, seals deteriorate, oil burn-off increases and sludge
can build up, which can all result in a decrease in engine performance and,
ultimately, reduce engine life. Mobil 1 High Mileage 10W-30 motor oil is
designed to maximize engine performance and help extend engine life."

 The Mercedes-Benz 560 SEC is quite an impressive piece of engineering.  To
consider using conventional oil in such a marvel of automotive finesse, and
even throwing in a few facts from GM, is like comparing roadside diner
burger (mystery) meat vs haute cuisine filet mignon.    In my many years of
owning fine automobiles and using synthetics for any age of vehicle, I have
never had ANY engine problems, not even something as minor as occasional oil
drips.    By the way, Mobil 1 has been around since 1974, which makes the
brand older than many of the vehicles in this forum.

 To summarize my experience and recommendations, use synthetic oil without
reservation in your 1987 560 SEC.  It will forgive years of using
conventional lubricants and improve engine protection and performance for
many years maximum cruising pleasure. (And who doesn't like THAT?)  :)
