14 Gl 63 burning oil
Hello
I have a 2014 GL63 and I've always had to add a quart of oil around the time my service/maintenance would be due.
because of the pandemic we haven't been putting nearly as many miles on the vehicle as we usually do but I've gotten the message to add a quart of oil three times since my last oil change. I've added twice and just got the third message last night.
I don't see any visible oil leaks on the floor or in the engine bay, but where is the oil going?
Anyone else experiencing this or know what I should look for?
not sure if there's any correlation or not but I did get a message to add coolant last night also but I think it may be to do with the temperature fluctuation.

Was it completely full after the oil change? If so, you could have an issue with cylinder scoring or bad valve seals. Valve seal leaks are a known issue with the engine.

I've been using them for a couple of years now and never had a problem before with their service. They've been the best dealership I've been to in about 20 years so far.
I'd have to go through my paperwork, but I'm pretty sure I had a cylinder misfiring and fail. I think it was replaced or rebuilt and that was about 2 years ago.
I hope that's not where this is going because it was a nightmare and they had my truck for about two months. Luckily I was covered through extended warranty, otherwise it was the worst experience ever with a MB dealer.

I always noticed that the top up when the light came on was not the same "full" as an oil change, I needed to top up regularly when topping up but not for a several thousand miles when it was changed and fully brimmed I guess.
Not to say you aren't experiencing a leak but the top up with 1 quart will not fully fill it in my opinion.

My ‘13 GL63 M157 asks for oil regularly aswell. I put 1L in it a couple of days ago and noted the km to keep track.
i hope there isn’t and compression issue. The mechanic said there is a leak at the front somewhere that will be repaired at the next service when I do the fan belt. No oil makes it to the floor though.

I just returned from an approximately 800km drive and used about 1 litre of oil in my 2013 GL-63. It doesn't seem excessively smokey - it puffs a bit out when I stick the boot into it, but I suspect this is fairly normal. It has a bit of an oil leak coming from the front of the engine, but nowhere near bad enough to account for 1 litre.
I've put a couple of bottles of Ceratec in it, thinking it could be cylinder scoring, but it's not throwing any fault codes.
I think it's time for a compression test. Any other suggestions what to check for?

I added about 1.5 litres of oil to mine and I think it was only about 2k kms since an oil change at the dealer. I noted the mileage so I'll report back on how much it's using when I top up again. It's currently waiting on a new transmission from Germany...
