Wondering how long my Turbo will last on my 2017 E300 2.0 (w213)
1. Mercedes never used "nissan parts" in the M274. The M274 is a Mercedes designed engine. The M274 was used in Infinity automobiles. Where the heck are you getting Nissan from now? You're trying way too hard dude.
2. I have two S Classes, an E Class, a GT63, and i'm looking to buy a CLS63 AMG in a few months. I have a Mercedes ML, and a 2020 VW Passat in Europe. I literally don't care that it happened to me. I have other cars to drive every day of the week on two continents. I take apart my E300 engine for fun and put it back together. So even if my S class did blow up, I wouldn't be mad about it. It's life, sh*it happens. I also got mine covered under warranty and sold it, so I never lost any money on it. So don't care.
3. I had to use lower grade octane because 93 octane wasn't available you flaming moron.
- Since you don't know the english language and can't read, i'll explain it one more time to you. My E300 that blew up I used 93 octane always. It still blew up. My current E300 i put in all kinds of low grade fuel and sometimes even 91/89 and I have 140,000 miles. Still hasn't blown up.
You literally sound stupid by repeating your self. I would suggest you just quit. No one said your car is affected by the bad wrist pins, no one said your cars going to blow up. It was said that hundreds of M274's engines failed from 2015 and on. The thread got derailed by you believing your cars going to blow up, which it more than likely won't.
Also another FYI - Using 89/91 octane won't destroy your engine over time. If your cars NOx sensors/ECU detects that you are using lower octane, your car will change the timing to compensate the lower fuel octane you put in to prevent pre-detonation. That in return will cause your engine to run less efficiently and lose some power.
If that didn't make sense let me explain it even further: It won't blow your engine.
If that doesn't make sense then go get your head checked.
You are dismissed, clown.
I never said they would blow up using bad gas lol!! Just a slow death.
GO bother someone else, you imbecile!
This is the second time i've ever put 89 in my Benz. I'm just telling you that It won't blow your car up. As I said before I don't think my brother ever put 93 octane in his E300 once. HIs car is at 130,000 miles. Still running like new. So not sure what drugs you're smoking but I would really like some of it.
And only reason i put in 89 octane is because I had to drive through Vermont. If you did drive through that state you would know there aren't many gas stations on the highways. The gas station I went to didn't have any 93 and the nozzle for 91 wasn't working for some reason, so I had only 89 and about 20 miles left of gas range, so I couldn't drive to another gas station.
FYI the gas cap also tells you that you can put in 91 if you didn't know. So you can use "bad gas" like you say (btw it's not "bad gas", it's just lower octane. I thought I sounded like an immigrant/foreigner but you really take the cake on that one).
You're also being laughed at by Mercedes technicians.
I'm too tired to converse with you anymore. I've literally lost brain cells. I am going to end this here, and unsubscribe from this thread to put everyone out of their misery. For the last time have a great night, thank you for the laughs and for making all of us more stupid. Cheers.

Modern day engines do have an electronic timing system for lower octane gas, but using lower octane gas consistently will eventually carbon up the engine. This is not an issue if you take apart the intake manifold and clean the carbon every 20K miles but that could get expensive if you are not a DIYer/

as for your carbon statement, that’s all true, but you’ll get carbon with 93 and higher octane fuels as well. I’ve already cleaned my intake valves twice. Used to clean carbon from customers engines all the time. It’s just the nature of the DI engines.
using 93 consistently I saw carbon build up at 20,000 miles after cleaning it. but the point is it won’t blow up the motor. Massimo thinks that using lower grade fuel somehow attributes to more wear on the engine or something that’ll cause catastrophic failure, which isn’t the case.
He’s just a guy who’s throwing sh*it at the wall and seeing what sticks. But unfortunately that’s not how the world works, and facts are facts.

I would call my AAA to have them bring me 91 octane gas or have it towed before putting anything less then 91 in my E300! :-)

I think your brain is seriously underdeveloped. You literally haven't proven me wrong once. I know English is hard for you so let me explain and dumb it down for you once again:
This is what I said: "#1. Mercedes never used "nissan parts" in the M274. The M274 is a Mercedes designed engine. The M274 was used in Infinity automobiles. Where the heck are you getting Nissan from now? You're trying way too hard dude."
I was talking about the M274 engine. If you want to get technical Nissan is partnering with Mercedes to make the new 1.2 and 1.4 liter "M260" engine that is replacing the M274 model. N O T H I N G you said makes any sense or has anything to do with what i said. Literally didn't prove anything. You/re just making your self sound really stupid at this point. But keep going, I keep sending my buddies that work at Mercedes screenshots of this conversation and we're having a good time laughing at you.
I would just stop if I were you Mr. "your engine will explode if you use 89 octane" 😂 😂 😂 😂 😂 😂 😂 😂
(BTW - my name isn't even Billy LOL)
I also said putting a lower octane in a Mercedes DI engine is a slow death of carbon buildup- the minimum required octane is 91 for most all Mercedes engines, my 10-year-old knows that, you moron.
Out of the hundreds of thousands (Millions really) of the M274 engines that was made- maybe only 2% had piston failure you moron!
Stuttgart and my local Mercedes dealership both also confirmed and stated the same thing: The affective bad wrist rings came from engine # 274 920 30 406602, not all of them- Not even close to my engine numbers moron!
SOME COMPLETE FROM A- Z PARTS FOR THE ENGINE WHERE MADE IN BERLIN, HUNGRY, ETC AND THOSE COUNTRIES (EUROPE) ARE NOT SHOWING PISTON FAILURE!...These cases are specifically in the USA, a lot coming from California- moron!
I talked to my local Mercedes dealership after giving them my Vin and other information and they told me as well my engine/car is not affected by this piston failure, NOT EVERY M274 ENGINE IS, MORON!
Never in my life have I seen such a hater- just because one of your E300s had a piston failure- you think everyone else will have it lol, it's just isn't going to happen moron!!!
Not every M274 component engine parts came from the Nissan plant, that was years ago and production for the engine parts for Mercedes M274 was short lived- Moron!
If that was the case- hundreds and thousands (MILLIONS REALLY) of the M274 engine would have gone bad by now moron!
PLEASE remove yourself from my thread, I can't dumb it down for you any longer and stop using my words like: dumb it down, find your own just like find your own thread- you babbling imbecile!

Sorry to heard about your E class cracked piston, did you have any engine mod of any form? Did you drive the car aggressively?

NO hes just a moron that thinks because he's M274 engine had a piston failure, everyone else will.
Common sense, which he apparently does not have, will tell you- out of the millions of M274 engine made, only 2% had the piston wrist failure, specifically in the USA.
Remember this is a guy that used 89 octane in a newer Mercedes engine, even if the engine electronically compensates or forgives, it is still very bad for a engine that is very complex and has low tolerances as these newer Mercedes engines do! :-)

You guys are ruining an otherwise good thread with your bickering! Nothing either one of you say is going to change the other's mind. So, please, let's focus on learning and the original question, which has nothing to do with pretty pistons.

At first I just thought he playing dumb, then I realized he was not playing dumb, he really is! LOL
Lets get back on topic for sure! :-)

You keep mentioning "low tolerances" like the M274 is a Ferrari engine or an F1 car. It's not that low tolerance. It can take a beating and isn't that sensitive to "low octane fuel" or "lower quality oil". I don't know what the hell you're smoking honestly. Again, i put 89 in because I was in a state with little to no gas stations for miles and needed gas badly.
Just to remind you, my engine has little to no carbon inside of it, look at the pictures i posted. The proof is in the pudding. and is more than likely healthier than your engine at 143,000 miles. So go touch grass and play with your little YouTube videos Mr "your car will explode if you put in 89 octane fuel"

"I also said putting a lower octane in a Mercedes DI engine is a slow death of carbon buildup" - Every DI engine will have carbon build up whether you use 91 or 93. Just differs from the quality of fuel and how you drive. The TINY bit of carbon that it might accumulate from using 91 vs 93 or 89 is literally so small that it wouldn't hurt anything. Again - not sure what the f*uck you're smoking buddy. No engine is going to "die of a slow death" because you put 89 octane in once. Literally the dumbest thing i've heard all year. And I deal with a lot of stupid people on a daily basis.
Literally a moron.
