Hi. Just got a 2021 glb250 13k mileage. Very low mileage with Amg package with 20inch rims. The car said service A1 is due in 114 days.

want to know if you guys do 7500 miles oil change or wait until 10k miles to do it .

I drive city 90% about 40miles each day stop and go traffic. Want to maintenance and not get the m260 misfire chance . What other maintenance I can do to prevent the misfire.

TIA

 

did u buy it certified?

I do it every 10k miles

 

No

im the third owner. The second owner got the car at 6700 miles as certified. They did service B and change brake pads too. According to carfax at the dealer. Then I picked up the car at 12.9k miles. I have about 14k miles and car say 115 days until service. I just want to maintain to prevent misfire haha.

 

We average about 55 miles per day 60% highway/40% lower quality secondary roads with very little city driving. The actual trips are 75-125 miles with days off in between. Our oil change interval is 10,000 miles.

For mostly city/suburban driving with stop and go, our preferred shop recommends 7500 mile oil changes with period not exceeding 6 months.

As for preventing the misfiring, I’m not sure anything beyond maintaining the best lubrication can be done. The problem is due to excessive valve guide wear from lateral forces. It is a design defect that is said to have been fixed in late 2022. There is an extended warranty in the U.S. covering some, but not all of these failures.

 

Attached find the "Service Sheet" for a '22 model, when you visit the MB Dealer ask someone in the Service Department for a copy of the '20. As you review the attached you'll notice it's an either-or trigger for a given service. One year or 10K miles whichever occurs first. For someone like me that puts 5-8K miles a year it's obviously less than 10K. I've read other threads and people say with the new oils 10K is reasonable.

 

@SRNH would this apply to a 23' AMG GLB 35? I called my local dealer and in short, refused to give me any details since it was an AMG model...

 

I'm looking for the 2024 GLB250 Service Sheet.. Anyone got it from their service department? I asked my Sales Rep and he went to the service dept and they told him that they are not suppose to give that document. What a BS.

 

If you look at the top of the 2022 specific Service Sheet I posted it indicates the Model/Chassis Code as "247.6". I've been looking this morning after your posted question and several sites indicate your GLB 35 also has a Chassis Code of 247, HOWEVER, they didn't indicate a suffix. So, determining your total chassis code is key to answering your question then you can seek the correct service sheet by Year and Chassis Code.

NOTE: The Service sheet is used by a mechanic with its call out to a specific "AP" task numbers in MB's service manual. Internally in their Service Manual DB It contains labor hours required for each of those tasks to ultimately determine a cost estimate.

 

247 is used in both GLA and GLB, H247 is GLA, X247 is GLB.

 

247.6 if I recalled correctly is the FWD version GLB 250, 247.647 is the 4MATIC version. Both codes applies to both pre and facelift.

The service sheet might be talking aboyt 247.6 lineup which might therefore include 247.647

 

Ok, so confirmed, I just checked and GLA 250 4MATIC is 247.747 while the GLB 35 is 247.651

 

As the GLB 35 only comes in 4MATIC.

 

Use the 2022 one, it is likely applicable to the 2024.

 

In 2016 I became aware of the Service Sheets during a conversation with my Service Rep and he provided me one for my W166 2014 ML350 BT 4MATIC. When I asked for one this go-around he had my Service Record Up for my '22 GLB 250 4MATIC, never paid attention to the suffix before, good info coming out on this subject.

 

I see.

 

So the service sheet I am looking for must indicate 247.651 or does that mean the 247.6 would suffice?

Happy to see the forum is still active and engaging; most other forums I'm a part of are dead.

 

Anyone doing 10k or even anything over 5k miles is just being foolish. 10k+ intervals are nothing more than marketing hype. Sure, your engine will be fine during the warranty period, but total engine life is shortened if you are thinking about keeping your car for a while. Oil is cheap compared to a rebuilt engine.

 

I agree @JettaRed we are planning on doing 5k intervals for oil changes.

Would everyone agree that the brake fluid must be changed out every 20k as well? Even cabin filters every 20K? Cabin filters are inexpensive enough, but the brake fluid job seems a bit extreme...or am I being ignorant? Any insight is appreciated!

 

247.6 should suffice.

 

Every other year.

 

Yes exactly, it is the blood line of the engine, think of it like the blood in a human body, it carries the contaminants to the oil filter (like the kidney) and you want good quality blood (I mean oil) circulating that engine. Otherwise, the contaminates acts like plague and clogs things... Okay this latter statement is a bit extreme but you get the idea.

 

I have another question for ya, boss - does MB have proprietary oil? Specifically, for the transmission fluid? My wife's 21' Touring Subaru Ascent had proprietary fluid and advised not to use anything else...the kicker was that that very fluid was on back order for about 8 months before we finally had it serviced.

 

not one at all : ) just sharings things learned from other forum members. You just need to look at the manual and it will list the specification needed for the trans fluid, it has a particular requirement of level of fluid and what temperature to check the fluid. Best to do the tranny fluid change with the help with XENTRY. It is not impossible to do it without XENTRY.

 

Once you have the specifications handy, go to operating fluids mercedes-benz and you can see all the fluid that is approved by MB from many engine oil brands.

 

Fortunately, being a car enthusiast over the years, I've made some good friends with the proper tools so if a scanner helps, I'm sure we can have that area covered.

Over on the Subaru pages, there were mass concerns about using anything other than the proprietary trans fluid, even tho companies like Amsoil claim to compatible, the community highly advised against it as it could damage the CVT transmissions. (The CVT may be the bigger culprit.)
