Use any of the good HDEO like Delo 400 which gives amazingly good results with MB diesels or Delvac Super/MX and your engine will run long.

Don't worry about CJ/CH ratings, the 229.3 or 229.5 meets all specs for your engine. There didn't seem to be a cost difference, with both types available at your FLAPS if they have a decent selection of oil. Often they will be called 'European Formula' on the front of the bottle and also meet a VW spec or two.

Castrol Syntec 0W30 European Formula is a 229.5.
Valvoline SynPower MXL 0W-30 is a 229.3.

I believe those will be the only easy to find ones in the US that are rated for FSS and a 0W30. There are also a couple of rated 0W40s. Delvac 1 5W40 is a great oil but is not rated 229.3, instead rated 228.3. It's actually a long-service truck oil and should work great, but why use it when you should be able to get a 0W30 or 0W40 rated energy saving oil that's rated for your engine and recommended by MB? Same story for the Rotella, 228.3 not 229.3, should be great but is off-sheet. There are no reccomended Redline oils. Not all Mobil 1 0W40 is 229.3 or better, so check the bottle. Autozone carries the Syntec 0W30, making it easy to find in the US, a higher-spec oil for your '99 and energy-saving to boot. It should be good to run anywhere except perhaps where it regularly gets over 110F.

BTW, best spot I've found for the list of all these oils is:

The so-called truck oils can work even better than the manufacturer-recommended oils when it comes to preventing wear. Over on the TDI forum based on oil analyses Mobil1 TDT seems to offer even more anti-wear protection than the VW-certified oils. But one has to be careful with the new generation of clean diesels as those require low-ash oils. That's not a concern with the OM606.

Yes, they can. But unless he's planning to do UOA, why not just go with the oil that's specified? There's even a readily available 0W30 energy-saving oil in 229.5, which should give him almost as much of a mileage boost as the 0W20 would, is reasonably priced for a synthetic, and so on. There are plenty of things we can guess at and probably be right - here's something where the manufacturer has already done the testing.

And to the OP: oil threads are always a powderkeg. Don't worry, use 229.3 or 299.5 in whatever weight you want, and you'll be fine. There are other options some people are proposing, and some of those might work quite well, but unless you want to do oil analysis, just go with the Mercedes specs.

With these long change intervals, I'm a fan of either going up-spec on the oil (used to run the 506.01 spec oil in my 2001 TDI) or doing UOA. It's just safer and easier, and the cost difference is tiny. In this case, you can do a 0W30 229.5 instead of a 5W40 229.3 for something like $10 more a change. That's a tenth of a cent a mile, which just disappears in the overall cost of ownership.

>> With these long change intervals..

I wouldn't call 10,000 a long interval - 9 to 12,000 has been a reasonably standard interval for many cars in the UK for at least the last 20 years.

Using the 229.5 oil in my OM606, I'm currently using 9,000 mile oil change intervals, which is the originally recommended oil change interval for my W124. However, I think this is rather conservative as oils have become a lot better since 1995. What is the oil change interval for the OM606 in a W210?

TMAllison · #35 08-22-2008, 03:06 PM

97 on using syn and FSS, it is whenever the FSS goes off, one year, or a max of 16K miles.

Number_Cruncher · #36 08-22-2008, 03:21 PM

Thanks Terry,

That's very helpful info. I didn't realise W210s had their oil changes controlled via a computer.

I suspect that I could extend my change interval from 9 to 12,000 without needing to think twice. Considering the high quality of the oil, and the long runs (for the UK!), perhaps I should be more bold, and extend the interval to 15,000.

Now, I need to go and change my oil to a 0W40 or 5W30 or anything except a 0W20.

You still don't get it. Gently step away from that E300 and leave the keys on the driver's seat. Walk Far FAR AWAY from it....

TMAllison · #38 08-22-2008, 03:43 PM

NC - The computer monitors trip length, coolants temps, etc and extrapolates oil life.

I drive 110 highway miles a day, FSS has let me go between 13k and 16K miles during the last 140K miles.

Lots of city driving and/or short trip durations will drastically reduce the interval. It goes off on others at 8 and 9K miles if that occurs.

Thecorrupterx · #39 08-22-2008, 04:14 PM

how much oil would need to be added to just change the filter and not the oil?

when I had my crown vic I would use mobil 1 EP and go 15,000 miles between changes with a filter swap at 7500 miles.

Your crown vic wasn't a diesel. With a diesel you have much much much more soot in the oil and it needs frequent changing. I change it all every 7-7500 miles.

Thanks again Terry,

Your usage patterns are quite similar to mine. 50 miles to work, and then 50 miles back home is, by far, the most common journey I make. Perhaps my considering 15,000 miles oil change intervals might not be anywhere near as bold as I had been imagining.

Not so. My 30 years old commercial Detroit diesel calls for oil testing at 30,000 miles and with testing every 10k allows 100,000 intervals. Mind it is running on low-ash dino oil and 2-cycle diesel is famous for dumping lot of soot.
I just went thru the oil shopping for my MB diesels. I was trying to find one with 229.51 rating for 320cdi, but didn't find it at 3 local suppliers. Mobil 1 0-40 is 229.5 rated, what is good for older MB diesels.

Isn't a big part of acheiving that interval due to the large amount of oil in the sump as compared to our MB's with a measly 8 qts?

I'm sure you would be fine at 10 or 12K miles easily. An analysis at 10k would tell you a lot. IMO the 606 runs much cleaner than the older engines and as you said, oils and filter technology gets better every year.

The 8 qts in 3 liter MB is large amount of oil. My old 5.7 liter diesel Oldsmobile had less than 4.
The 15-liter Detroit holds 24 quarts of oil.
As far as I know the newer diesels we are driving are allowed in Europe 40,000 kilometers intervals.
