The color does not say much. To be more certain, I would send a sample of the oil after 5K km for analysis, if the results say it is still OK I would leave it for another 5K km then get it analyzed again.
I'm surprised no one has mentioned fleece vs paper filter? I moved to a fleece filter and a 10k change. With the regular filter I was at a 5k change. Always using the Mobil1 0W40
Good question texholdem. I thought MY 1998 was the 1st year MB went to the FSS system that requires the synthetic oil and fleece filter. If the threads are the same I guess the never filters will fit.
By following the FSS... I change mine every 10-12k miles (whenever the wrench tells me to). My oil is still a honey color at that point... darker by all means, but still honey... but like texholdem said, color doesn't mean much.
I guess you've done the research and it's not available?
I purchased mine at autohauz and have seen them on ebay.

I use a 5W/30 synthetic GT-1 blend oil. Change it every 3,000 miles with the filter. Call me crazy but with 174K miles on the engine now it makes me feel better......and thats all that matters. I guess its like blood to my mind. If its got dirt in it it might be bad for the engine.....................
When I changed the oil guide tubes last year I was amazed at how clean the engine was on the inside. At that time it had about 165K miles on the engine. I'll just keep my 3,000 mile oil change schedule.
PS: I NEVER ADD A DROP OF OIL BETWEEN CHANGES. It never uses any. Whatever amount goes in the filler cap at the oil change comes out the oil pan drain 3,000 miles later. Try saying that about any 1997 American made V-8 engine with 174,000 miles............... :thumbsup:

Okay, you're crazy (hey, you said to call you crazy...).
Seriously, I appreciate the OCD aspects, but you're throwing away oil that is better than what is poured new into lots of cars on the road. Pay $25 and have it analyzed, and run it until you're into the 80% range. You won't hurt your car one bit and you'll be doing the environment a favor as well as your pocketbook.
FWIW, it's no wonder it doesn't use any oil, you change it before it has a chance to.
(Yeah, I'm joking.)Not an American V8, but my last car was an American V6, a 1994 Grand Am. I bought it used with 35,000 miles. Started it on Mobil1 immediately and changed it every 5,000 miles for a while, did an analysis and extended it to 10,000 miles with a new filter (and top-off) every 5,000 miles. At 150,000 miles it still did not use oil and peering in under the oil cap it was still clean atop the valve train, usually got around 30 mpg on the highway. Yeah, I attribute all of that to Mobil1. Engine was still running strong when I gave it to a struggling family who were happy to fix up the other little niggling things (leaky PS hose, noisy CV joint, I think that's it).
Take care and enjoy the ride,

I've run synthetic oil (Mobil 1 and now Castrol Syntec) in all my cars (American, German, and Italian) for the past 20 years, and always changed the oil at 10K mile intervals. Mobil used to claim their oil was good for 15K miles, and I took their word for it.
I've had no problems whatsoever. I've driven two Audis past 250K miles on the odometer with no issues, and now have 160K on my E420. I pulled the oil pan off my car this past winter to change the oil level sender, and there was not a speck of sludge anywhere. And I have not had to add oil to my cars between changes.
I used to change non-synthetic every 3,000 miles, but with synthetic oil why bother unless it makes you feel better?

Don't be so quick to slam detroit. I can point to 3 examples of good old detroit Iron that don't use oil. at 185K miles, my 95 s-10 doesn't use any oil between 5k changes, when I sold my 87 chevy van with 190K didn't use any either, nor did my 84 pontiac at 160K when I sold it. My dad had one of the last big lincoln town cars with the 460, late 70's maybe. Didn't use oil, didn' leak, (engine or transmission) when he sold it with 290K miles on it. All of these engines had conventional oil changed every 5K to 7.5K miles.I use a 5W/30 synthetic GT-1 blend oil. Change it every 3,000 miles with the filter.
