Is this overkill?
Am I too much? I for one plan to do oil every 6500 miles (and not the 13000 the book calls for), but even with that, I feel that the first 1000 miles worth of driving leads to too much contamination of the oil to keep in the engine for another 5500 miles, let alone 12000...
Anyone else agree?
I'll tell you what really is "overkill": $120 for an oil change. Yeah, I know synthetic oil is costly, but $120?

I've changed oil religiously on all my cars every 5k miles without any engine damage whatsoever. With synthetic oil, 10k frankly seems reasonable.
Happy customers are repeat customers - you can argue all you want about planned obsolesence, but in the end it's the repeat revenue that sustains any business.
I know that some feel that the break-in is not as important as it used to be, but you can never be too safe I always say.
Thanks for the opinions.

Count me in among those who agree with you about the 1K initial oil change. I don't think that's as necessary as it used to be in the olden days (since technology now builds things to much better tolerances, there's fewer particles floating around) but even at the $120 ripoff price point, I'd sleep better knowing it was done.
As far as 6,500 thereafter, that's all a matter of opinion, but unless you're particularly hard on how you drive (lots of short trips, rapid acceleration all the time, high revving to shift points, etc.) you should be good at least until 10K. In my old domestic car I changed to Mobil1 at 35K when I bought it used. At first I was doing changes at 5K and then went to 10K with a filter change at 5K. The oil always came out looking excellent and the car ran great until after 150K (when I bought the Benz) with no more oil consumption than it had at 35K, which was very little anyway and much less than it's brethren with fewer miles. No visible sludge, etc. and better mileage than others of it's ilk as well. Made me a BIG believer in Mobil1. Based on that experience I decided when I bought my Benz I'd follow the FSS but never more than 10K; but that's probably still overkill, particularly with the oil capacity in these engines.
Hey, there's my 2 cents worth! No matter what, enjoy the ride, man.

Of course of you lease or trade every few years, it's not your worry.
Every European auto manufacturer that I know about recommends a break-in procedure. They do it for a reason. If one or more American manufacturer's don't do it, so what. They aren't interested in long term relibility anyway. They never have been.
They're more interested in playing games with their CAFE averages than in building cars that will run for decades.
We drove our 190D for 17 years and only sold it because we moved. It still got more than 4K miles on a quart of oil when we sold it.
My 1991 300E gets over 5K.
My new E320 appears to have only used .3 liters in 7,000 miles. Each one of these cars was carefully broken in.
I also plan to change oil before the FSS system tells me to. I should have done it before now but I have two new knees which has kept me from doing the work. I simply won't pay a dealer $100/hour to change the oil.
I know that some feel that the break-in is not as important as it used to be, but you can never be too safe I always say.
Thanks for the opinions.

You guys ever heard of changing your own oil and saving $100? It takes about 10 minutes total and you can get the filter from your dealer. I for one am leasing so I'll stick to the schedule but honestly I would change every 4000 miles if I owned it.

At $120 is a bargain from the dealers, considering Mobil1 super synth costs $4.99 each quart we need 8.5 qt for E350, that around $48 for oil $20 for filter and $30 for a local shop to change it. Plus getting those parts takes a lot of driving around and shopping on the net to buy, where at a dealer it's a one stop shop.

Talk about investments.... I only wish I invested in Mobil and was your mechanic....
It is hurting your wallet, and my Scottish nature to see you wasting so much money!
'Course if you've such deep pockets so that you can afford to throw good
money away for no good reason, that's entirely up to you.
It's too bad that those old ideas die so hard.
The days of three thousand mile oil changes are long gone.
Even VW used to say for the TDIs and maybe still does with the new PD
diesels to NOT change the original factory fill until five thousand miles.
Then it's every ten thousand miles thereafter.
Those of you that insist on changing your oil so early are only making the oil
companies richer, and aren't they getting rich enough already?
Why not do an early oil analysis and let that relatively inexpensive 'blood test'
for your CDI determine when you should be changing your oil?
I think you'll be surprised!
That said, my point was, since in my case I'll be keeping for about 7 years (at least 2 years into the next E class) and well over 100,000 miles, a $90-120 extra service 2 times per year (costing me not more than $1000 or so over the 7 years) is a lot better than $3500 for a new engine or major fix at 51,000 miles.
Consider it "self insurance" and not an investment that I am doing this. As my original question asked... "am I overkill?" .. I guess it is overkill, but then I'll sleep better at night doing it.
My curse was to study Mechanical Engineering as my undergrad, and all of my memory of various labs where metal grinds on metal comes to mind. Even with the best oil, metal is going to come off... this is far more likely at 500 miles, than at 5000 miles.. so the majority of your contamination is going to happen early on.. do you want to keep it in your crankcase for the next 12000 miles? I don't... but you can if you'd like.
As for MB telling me I can change my oil ever 13000 miles... that's fine, but they want to sell you parts and new cars, not keep you in that same car for 20 years. That may have been the mind set of a MB of the past, but todays MB is more American in their corporate planning, and less German. Think "quarterly earnings, and sales growth"

I agree with you on changing the oil earlier than the FSS intervals. I have talked with several of the techs at the dealership. Many of these are driving MB cars themselves. They give lip service to the factory FSS intervals and change their own MB car's oil at 5,000-7000 miles.
I disagree with your point about MB wanting customers to change their oil at longer intervals so to sell more cars. But do beleive its the oil companies that are the ones pushing the early oil changes for obvious reasons... Its been that way for decades, and as Green E-300 DT pointed out these are old habbits that seem to be hard to break. Yea, oil is alot cheaper than engine wear and the oil companies are also well aware of this and prey on the paranoia and "old school" thoughts of consumers... You call it cheap insurance and I call it a waste of money. That being said.... Its your car and your money, so do as you will...
Goodluck and enjoy your purchase

Since you are "only" going to keep the car until approx. 100K, then don't strees yourself. Granted you spent a lot of money on a vehicle that you want to make sure will be problem free for the duration of your oenership but changing the oil so early without any objective results is indeed overkill.
I too was interested in the oil change interval on my diesel, so I perform oil analysis to objectively show me what is going on with th eoil in my crankcase. On my E300 with the OM606 diesel, I can safely travel 8,000 miles on the same oil and keep going a safe additional 4,000 if I wanted to. Keeping in mind that my engine is indeed broken in with 168,000+ miles while your's is brand new.
Also you need to consider the increased efficiency, cleanliness, etc between your diesel engine and my OM606 are worlds apart. I would definately give that oil in your crancase some more time to do what it needs to to let everything settle in and seat properly.
