Why am I getting a service indicator at 5K miles?
On a side note, they recommend you to flush your first oil at 1K km which I did... so if you are at 5k miles on the initial oil, I would flush it for the first time to get rid of some metal debris that might be in your oil.
I received it in March. It is probably close to a year now that it came off the production line and the service indicator calculates both mileage and elapsed time, then calls out the need for service when the first of both criteria is hit. I will observe the interval between the first and second and see whether my theory gets confirmed or disproven......
Edit: missed the other posts while I was writing. Guess I'm due for full service A then. Looks like it's time for me to get a vac pump, filters, etc.!

Yes, only oil & filter change for 1K & A service.

My dealer never said a thing about this.
When you say its recommended, by who ?
Thanks !

Alot of people will tell you to change at 1K because the engine is still new so there may be a considerable amount of metal shavings coming off from the engine so that's why.

In fact I had 5 oil changed in 4 years of ownership & within 12k km.. Overkill? Maybe but lately I get my oil changes for a great deal @ my friend Indy shop. I no longer go to the dealership since I found this option 2 years ago.




As an example I did my first oil change at one year and 6499 Km (~4100 m) and the factory fill M1 oil sheared from a 0W40 to a 0W30. Also wear in metal levels were a bit high. The TAN (Total Acid Number) outran the TBN (Total Base Number) and its ability was reduced below zero as acids built up. The factory fill M1 was done and needed to be changed now and not run further to the 15000 kilometer (10000 mile) factory service interval.
Here is a copy of the oil analysis that was done at the time.

I start seeing the same pattern throughout the forum: There are lots of posts with guesses, speculation, opinions, emotions, etc. They keep going with dozens of equally unhelpful add-ons.
Then there are others, with a factual, well researched answer, and wham: The thread is dead. Many times not even a thank you. Strange really.
Well done, Mort! :-)
Thanks again - ordered my filter yesterday and will change it before putting it away for the winter :-(




If the factory fill in your C63 is similar to mine the TAN is > TBN and the oils ability to fight acid wear is depleted. The longer the oil sits in the sump, in this condition, the longer the acid has to wear at the engine internals even if no further acid is produced from combustion. Mind you at a decreasing rate. I don't think the TBN will reduce further without being run. I generally let mine sit until the year is up and change it in the spring, just before putting it back on the road after the winter. This year I think I will change it up and do it this fall as the registration just lapsed and it is off the road. That way it will have fresh oil in the sump sitting over the winter and my year cycle will advance from the spring to the fall.
