[W126 Coupe] Oil for 560 SEC

[Shayegan, Richard]

Hmmm, they've given the oil it's own website now
http://www.joegibbsracingoil.com/ but they've also dumbed down the FAQs
so they just tell you not to use the oil, not why. Well, I forget what
it was, but certain ingredients which are present in all oils are
elevated greatly in race oils, which in turn gives them a service life
of 400 miles or so in addition to messing up some stuff.
 
If an engine is in good shape, my thought is this: Aston Martin,
Bentley, Porsche and MB AMG's recommend Mobil 1. They don't like their
cars to look bad. Certainly Porsche could and would get whoever they
wanted to be their official oil, there's got to be some reasoning behind
it. BMW says Castrol RS or TWS for the M's (depends on the years), but
BMW also has Castrol make them a special blend. Somebody out their would
recommend one of these one off oil companies' products if it really were
better for a street driven car. Now of course an older engine with miles
on it won't like synthetic if it's consuming oil (heck, TWS might as
well be a one-off oil, you can never find the stuff, so clearly
availability isn't an issue when they choose...heck they could do what
BMW does, sell it at an inflated price through the dealers and make even
more money).

	Richard, 
	Can you send me the link. I looked at the online  store and I
can't find anything about oils.

	If it's a true racing oil then it's not for road cars. If you
want to read why, just go to Joe Gibbs Racing's website, then his online
store and see what it says about the oils (namely not to use them in
road cars and then it explains why).

		I have always used a full synthetic oil in my car (for
the past 10 years)
		Reading the posts, this does not seem to be favoured?
		Use Total Quartz 9000 which has recently be repackaged
in our market as Total Quartz Racing 10W50.- full synthetic.
		Specs: ACEA A3/B3 API SJ/CF.
		Any views on this?
		I don't have any engine issues yet. Car has 160 000km.
No noisy engine on start up like some other old Merc V8's I've owned
		and this cars dyno output is still exactly as per the
book so I assume cam wear is negligible.

			I'm curious to see what the oil experts have to
say about fuel washing. 
			3k oil changes, from my understanding, was a
number based on older additives from the '60s and '70s. 
			With leaded gas gone and the auto industry
demanding better oils, 3k oil is considered (I thought)  to be in brand
new
			and 5k to 6k changes the standard. I've moved to
4k-5k and have had no negatives. The drained oil still looks nearly
brand new although I have not had it analyzed. My '84 chevy silverado
truck with a 545cui has 278,000 miles on it and my MB has 167,000 miles.
The timing chain is just now worn enough to begin to be of concern .
Compression is perfect and oil consumption is normal.
			Perhaps we are all being overly concerned about
this oil business and the short change interval may be the key to
longevity, regardless of the oil. 
			I also consider it beneficial to the environment
to extend the oil changes. (but that's just me)

			Interesting, in my chats with Valvoline and
Mobil engineers they have both Strongly recommended use of their diesel
oils in our older gas engines.
			
			The diesel oils have additive packages that are
far closer to what was around when our engines were designed.  New oils
with  new engines/tolerances/warranty concerns in mind do not...even the
high mileage oils formulations have been changed to a degree that could
negatively effect engine wear. 
			
			I have a good friend/mechanic who's 280TE which
has had the ever living snot rung out of it for the past 80 of it's
almost 300K mile life run on a strict Rotella diet.  After a recent
valve job and inspection of the cylinders they were nothing if not near
perfect. 
			
			I have also b/w clients and my personal fleet
run up in excess of 80+ thousand miles on Rotella/Delo.
			
			I am particularly fond of diesel oil in engines
that haven't had regular oil chances and have sludged up quite heavily
internally.  I have one customers 560SEC w/ 190K on the clock, when it
arrived the heads/valve covers had heavy deposits.  It has now been
almost 3 years of Rotella every 2500 miles and the internals are night
and day from where we started. 
			
			I'll be attending a Mobil engineering convention
in the coming months at which point I will get more info to support the
above.  Ideally, I'll have some of it in writing.
			
			Lastly, IMHO, 4000 miles on conventional oil is
too long.  If I'm doing strictly highway I'll change every 3000, serve
duty/city driving I'll change b/w 2 and 2500.  As such the internals of
my engines stay near spotless.  I will only consider extended drain
intervals when running Mobil 1/Amsoil/Redline oil.

			Jonathan,  
			It's my understanding that oils (like rotella)
which are designed  for diesel engines should never be used in a gas
engine.
			The main issue is fuel washing and the second
issue is reactivity with sulphur compounds. 
			The Rotella is not resistant to fuel washing
from gasoline so the rings and cylinder walls are left unprotected with
the obvious result. 
			Personally I've always like Castrol 20/50
mineral oil changed every 4k miles and as an engine ages, I"ve started
to use High Mileage for my car.
			Does anyone have any other thoughts

			I like Rotella 15/40, although w/ the new
formulations and their lack of ZDDP I now add GM's tappet/cam lube to
bring levels back up to pre-2007 specs.
			
			Or, if you engine is tight/leak free I'd run
Mobil 1 20/50, but again w/ the same additive.
