[W126 Coupe] Oil change

[gary wingert]

I worked for Mobil Oil back in the '70's training dealers how to run service stations.  They gave us the opportunity to run Mobil 1 for free in our personal older vehicles.  I ended up losing an engine because of it...however, that led to changes over the years and I agree wholeheartedly with 190girl.  Synthetics work great.  I have a 1967 Mercedes 230 sedan with over 515,000 miles on it (no rebuilds) that has run Amsoil since the synthetic became available (there is still the remnants of the toilet paper filter it ran for a while!), I have a 1967 Chevrolet El Camino with over 512,000 miles that has been running Mobil 1 since before I can remember...probably 200,000 miles.  My 500SEC Cabriolet has 246,000 miles and also runs Mobil 1.  All I can say is I can run them longer without worrying that the lubricant is going to break down.  With 9 vehicles I can't spend all my time changing oil.  I'd prefer to have a life (what's that?).

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?)  :)
