I seriously doubt if any special additives are added at the factory as the factory recommends against additives, and I doubt they would use moly. Moly is a great friction reducer. But it could also prevent the piston rings from properly seating. You need some initial wear for piston rings to seat properly. All these people have "sources". Show me something from MB that is official.

After 15 years in auto manuf. across 3 major OEM brands, none add anything special.. (Toyota, Mercedes, MTU).

The grade we use in factory is designed to permit correct running in, performance and engine preservation over the first service interval.

Little is gained (piece of mind maybe ) from early oil change out IF the specified grade and spec of oil is used under "NORMAL" operating conditions.

This last point is the important one... if you are going to subject the vehicle to extreme conditions, track use, extended towing, extreme climate, then it is of course advisable to adjust maintenance in line with usage. With so many variables in usage generalising here is largely worthless...

"Recommended" factory service for your GLC - every 10K miles or 1yr - whichever comes 1st.

Your 1st/10K service is termed "A" service - and the 2nd/20K service is termed B service.

I have attached a link below which you can use to download the Maintenance Manual for your GLC which will give you more specific on the recommended service. SUV&engine=undefined

Please note dealers are allowed to set their own prices for service - so if you have more than one dealer in your area - when service becomes due it can save you a bit to call and ask/quote.

Going into your 2nd/20K service - if you are planning to keep your GLC past 40K miles - before your 20K service - before checkin - you can save a bit by asking those dealers to quote you "3yrs Prepaid Maintenance" which will cover you 20K/30K/40K and save you a bit more.

Enjoy your new MB - keep the beat !

Sorry to revive this old thread, but it appears finding the maintenance manual for the GLC300 SUV is harder than I expected. The link above doesn't work and if you go here: SUV&engine=undefined the GLC SUV isn't even there but the coupe is. Anyone have a known good verified link to the proper "booklet"?

I looked through the manual and it doesn't say anything about when to do an oil change. Only that the car takes 6.9l of oil.

I'm at only 5,000 miles now but my understanding is that the on-board screen will show a notice that "Service is needed" at or before 10,000 miles.

Ok. Thanks. May will be 1 year and the car just passed 7,000 miles.
I usually do my own oil changes. Is there anything tricky about a change on a GLC?

I like the oil change interval on the newer class 8 trucks - the big ones - 100,000 miles. Twenty five years ago it was 25,000 miles.

Interesting in Australia the first service is at 25,000kms, 12 months or when reminder pops up on dash, which ever occurs first. Whilst this appears long, my dealer reassured me. I just follow the manual and just had 2nd service at 50.000kms. All good.
