So my baby is at about 5.3k miles at the moment. I'm wondering if I should do a early first oil change or wait for the appointed 10k.

on a side note does anyone know of a DIY thread for coils and subs? I did a quick search and nothing on coils and subs were all self contained subs.

I am going to the dealer tomorrow for the first oil change at 2450 miles, really low miles. I am not worried about the one-year service requirement at all, but worried about not having a dealer recorded service causing a voided warranty.

I will see what I would do after the first oil change.

Your warranty cannot be voided because you did not get service done at the dealer.

Google the Magnuson-Moss warranty act. Unless they can prove you caused it/something you did to the vehicle directly caused a problem, they cannot void your warranty or deny a claim. Additionally, they cannot void the entire warranty on a vehicle over something such as this.

Example: You replace your stock exhaust system, now they will not cover warranty issues for the exhaust. They can't deny you a broken power seat motor because of this... etc.

Thank you for the info. Yes, I hope MB warranty is the same as my other Japanese cars. What about something "kind of" related to my mod. I installed my rear-view camera. If other electronics fails, and dealer found this after market added on camera, they might say "oh, you added that thing which might be the cause of the other failure...". No one can install it exactly the same MB way so there is a hole there for dealer to reject customer's warranty repair. Hopefully they are not that picky.

holy good lord that was a long read. Basically all I got out of that was.. YES CHANGE IT, but not because my oil needs it, but because my filter needs to be replaced from all the crap that settled during my break in period. Correct me if I'm wrong.

Total out of pocket is $98. Although oil change only, they included lots of "visual" check and fluids under the hood.

Service advisor received an email from his manager saying if it is not a full service such as Service A, he can't reset the service reminder. I got an email before his recent email and was told they can reset it upon customer's request. I said I will reset it myself.

bringtherain

wait $98? thats just for the labor right? Oil alone is near that amount

MarcusF

You are 100% correct. As your engine breaks in, parts wear. As they wear, the oil filter gets loaded with particulates (metal bits mostly). MB does a fantastic job at engine assembly, BUT every engine still has break in wear. So like Nike says –

C300CA

$98.13 includes everything, oil, oil filter and labor. It is a discounted price. The other closer dealer wanted $120 + tax for oil change.

C300CA

Forgot to say $98.13 is the out-the-door cost. Before tax is like $89. This dealer is about ten miles further than the $120 dealer.

awesome time to do my oil change then

how did u get a discounted price? at only $90 i'll definitely do it. 8 quarts of oil alone is gonna $70 as it is + the oil filter and labor $90 is a steal for a dealer price

C300CA

I called Smythe European. They wanted $120 for oil change and would not reset service reminder. Then I called Beshoff Motorcars. They wanted $89 but said they could reset service reminder if customer request it. I didn't ask for a discount.

bringtherain

sweet i live 10mins away from beshoff. wouldve gotten my car from them if i didn't know the sales director from autobahn

C300CA

Mine is also from Autobahn, sales person is Ernesto. He gave me 11.55% off MSRP, plus an additional $1000 off if I show him I have other Luxury cars (RX300 and QX4). No one else seemed to really want to match that, or they wanted but had no car I liked.

Yes, that is the logic for replacing the fleece filter earlier than the standard interval MB mandates for filter & oil. But, if you are close to 1 year use, consider it your 1st official oil & filter change.

I'd do 1st filter and oil change early in 6 mos and/or 5K miles if you live in a very hot climate, as the factory fill is a relatively light 5W-30 oil.

Many MB Dealers are now using Mobil1 ESP Formula M 5W-40 oil, which had recently been limited to diesel engines only. Most suggest Mobil1 0W-40 instead, a better oil. ( Castrol 0W30 for cold climates ).

What model C300 do you have?

sport RWD, and fixed my garage

10k is not outrageous with 8.5 quarts of oil even in this first fill. I actually went 13,000 miles on mine, and the car runs and analysis look good on it today. The break in oil is a 5w30 Shell product and it's stout. It's actually nearly as thick as Mobil 1 0w40 once the 0w40 Mobil 1 gets a few hundred miles on it, it sheers. The TBN is very high on the break in oil too. It can go the 10k miles.

However, if I could go back in time, I'd probably change the oil or take it in for an "oil only" change about the 5k mile mark.

There will be a good bit of break in metals in there right now and there still will be for the first 2-3 oil changes, however, the most will be right now.

Therefore, if I could go back in time, I'd take the car in at about that mark for an oil only change (and still do my regular service when the maintenance indicator recommended it).

Now, if you are close to the regular service, like just a couple months, you might not want to do this now.

Also, if you're only going to be putting on 1-2k more miles before regular A service, that would be another reason to just wait.

C300CA

A side question: MB service advisor said once a car goes from regular oil to synthetic, never switch back. I think he means switching back will cause damage to engines. However, lots of people say it is perfectly ok to switch back and forth, and there is a reason why it doesn't hurt anything but I don't remember.

mac911

As Mobil 1 says in one of their YourTube videos, "Absolutely, Positively, False." On a car that doesn't require synthetic oil, you can switch back and forth between synthetic and conventional, all you want. You can mix them too.

However, the Mercedes cars of today require synthetic oil, so you won't be doing any switching. On a gasoline powered Mercedes, you must use 229.5 spec oil.

If the metal is in there, and not in suspension with the oil, by just changing the oil and not the filter, not sure what you accomplish, as the metals must be lying on the pan. Unless you are suggesting the metals are in suspension and too small to get caught by the fleece filter.

He already stated his miles, and I said "But, if you are close to 1 year use, consider it your 1st official oil & filter change." Sounds the same, no?

mac911

Yes, this would effectively be what I meant. If you look at an analysis on a factory fill, you can see iron numbers of 100+ PPM, not always, but not a surprise if you do. If you change the oil, that will drop dramatically until some more wear occurs. Once the engine is broken in, over the entire OCI, this number will be as small as +/- 10ppm. There is also more copper and other metals in the oil, when the engine is new.

Got-it, thanks.
