Changing the Oil myself on a 603, any special procedure? - Page 2 - PeachParts Mercedes-Benz Forum

You should not be running 8k miles on Delo...switching to Mobil 1 Turbo Diesel Truck Oil (Synthetic) will do wonders for your engine and longevity. It will quiet down your lifters and make the engine run much more smoothly. I change mine every 9-10k. Others on the forums have done oil analysis on this oil at 10k and it was okay so 10k is fine.

Respectively, My lifters are quiet and my engine already runs smoothly.
Motor oil has came along way, you can do oil analyhsis on Conventional 15W40 HD oil at 8-9 k and it will show good, all you have to worry about is soot contamination, that will happen long before the oil is worn out. so unless you run high EGT's and or dont allow for proper turbo cool down time, Synthetic engine oil is kind of a waste of $$$ in a Diesel from what ive learned.
But to everyone there own. Im just one person last time I counted.

just go to (B*# is the oil guy. com) if you dont believe me.
its like the PP of the oil community.

I used to have an 86-87 Euro 300D... and I distinctly remember having difficulty removing the oil filter cap... yeah, maybe they did equip the 124 with these and were eventually updated.

Just out of curiosity, what soot levels are you seeing at 9k miles? And, is your EGR deleted?

On my 602 (5-cylinder and with EGR still intact), I did an oil analysis at 7750 miles and soot was 1.1%. Not alarming in my view (I use M1 TDT), but I decided to play it more conservatively and stick with intervals in the 5-6K range. Part of my logic is that, if I ever have a timing chain snap, I don't want to be in the position of saying, "If only I had changed my oil more frequently!"

There was a long and interesting thread a while back on acceptable soot levels.

FWIW, while there are heated debates on this forum between dino and synthetic, everyone here seems convinced that one should only run longer drain intervals with a good synthetic.

I have not done an check on soot level for my oil yet, but I have have tons of buddies that run Cummins and Powerstrokes, and they just Belt out smoke when they drive hard. tons of soot, which means more going into oil. Way more than what my car would produce, at around 10K my friend did a soot check on his oil and It was 1.8%. less than 2% is safe.
His truck sees way more severe driving than my Benz does so I figred since Im running All stock, Except re route vac lines and EGR blocked off. I should be perfectly safe up to 8K.
When I get upto 5K on this oil I will do a check to see where I sit on soot and oil breakdown.

Just to set the record straight, Im not trying to tell anyone to do what I do or My way is the right way, Im just telling you how I do it,
If someone finds a major flaw in my way of doing it, Please let me know,
I can only work off the Knowledge I have been taught or have learned thus far. I have a passion to learn more. so Please teach me, I love reading.

The following thread I started a while back may be of interest....on acceptably safe soot levels.

Acceptably Safe Soot Levels: Can Anyone Speak with Authority?
