Lots of different oil choices are rare, if not impossible, to find at the moment. I think my car calls for 0w-40 European Blend and last time I was in Walmart, they didn't have any, nor did Costco. You may have to change brands or delay changing your oil a little.
My Walmart had it this morning, probably a logistics thing, I use the 10W40. why would you use a 0 weight oil unless you have average temps below -5 F ?

PJ, I'm sure you meant to write -5° Celsius (+23° F)
The local MB dealers here in DALLAS -- at most 3-5 days yearly below +32° F -- use Mobil 1 0W40 for oil changes, and the car came new in Florida with 0W40. The local Walmart has 0W40 and 5W40. I can't say I've ever seen 10W40 here. I'll have to look next time I'm there...
I've used 0W40 for 21 years in the much older C-Class without any issues at all. I guess I'm not an oil ****, any more than I am a fashion wheels ****.

No I meant Fahrenheit like the chart in the manual says, I have used 10W40 for 20 years as well without issue. ??????? Inference ????

So, to review (another way of looking at the chart)... All five viscosity grades are GOOD at +23° F, (equal to -5° C), and each of the three, left-hand viscosities are equivalent to -4° (-20°C).
In short, I don't see any reason to choose one oil over another among the three viscosities on the left. Except (subject to correction) if you like the quick warm-up in the Winter afforded by the thinner (0W40) grade. I certainly appreciate it.
Last oil change I got from the dealer (they were running a special) was 5W40 according to the receipt, I live in Cali and we don't get sub-freezing temps very often.
I was planning on sticking with Mobile 1 if I can, but I've also considered Liqui Moly Leichtlauf from FCPEuro. Does anyone have any experience with this particular brand?
Many oil suppliers are having a very hard time fulfilling orders. I was told by an oil rep that it was due to the winter weather in Texas shutting down the chemical plants that make their additive packages, and not actually the oil itself that's the problem. I hope people are not just looking at the weight in their owner's manual, but looking for the Mercedes spec 229.5 on the back of the bottle which is as important as the weight for long term health of your motor, as it indicates what additives can be used.

I've also heard good things about Motul.
Thanks for the help.
Walmart carries 5 quart jugs of Mobil 1 (pick your visc.) for $27.XX. Buy two jugs during Mobil's annual rebate (Sept.-Nov) and it makes no sense to experiment with other brews.

@DFWdude Yes, I know, but the point is walmart doesn't list it anymore, and several others have said it's not available anymore. That's why I started this thread.

Walmart website DOES list Mobil 1 0w40. I just checked for it
Website shows it is in stock at one of the 4 stores in my area, so you just have to look for it. The other grades are also hit-and-miss available, so it may just be a temporary supply chain issue, or as suggested in post #10 above.

None. I use 0w40 because both of my MBs were delivered to the US with 0w40, all the Dallas dealers use 0w40, and that weight has served my older Mercedes well.
I imagine there is nothing wrong with 5w40, either. Spec 529.5 is the only necessary item, and almost all Mobil 1 grades conform.
Well local Walmarts didn't have any Mobil 1, but I found Napa had it on sale so picked up a bunch and used the Mityvac to change to 0w40. Pretty happy with the process, FCPeuro for various parts and filter.

I've used Liqui Moly 5w-40 2 times on my sons oil change and Mobil one 5w-40 once and 0w-40 Mobile once since we owned it. I can honestly say I'm not a oil **** either but seems like to me the Liqui-Moly runs a little smoother. Between the Mobile 5w-40 and 0w-40 I noticed no difference and I stay in the south.
Dnasty: There is no way to tell if it runs better, it just seems obvious to do it. It's like taking a multi-vitamin, can you tell the difference? No. Is it better you? Yes.
So I think it's funny when people say their car runs better on xx oil, or when I changed to xx brand oil it runs better. Comparing old oil to fresh is what they notice and probably all they notice is it's quieter because that's what thicker oil does.
There is little to no zinc or other goodies, viscosity included, in most oil today, thanks to the EPA. My car never sees 32F and I'd imagine 99% of the time it's 50+ when I start it so there is zero no need for substandard oil. It does see more abuse and heat so all the more reason to use thicker and additives that can help. Of course there is a thickness limit as well, so there is a sweet spot in the middle and you just have to decide what it is. Guessing 20wt may not be perfect but it beats 0wt.
The oil the dealer suggests is dictated by the EPA and they doesn't give a crap about your engine. I've never followed what the mfg says for tire pressure, antifreeze or anything else. I probably use what the mfg suggests if nothing is preventing them from suggesting the right thing. Nothing comes to mind but I'm sure there are things. Or I may use what they suggest if it's easiest or all that's available.
Each car and conditions it sees are different so each ones needs will be different. Will any car eng run on 0wt? Sure. Will ANY car eng be better off using 0wt instead of 10wt? I can't imagine how that is physically possible so I'll say no.
It is entertaining how oil posts play out, and sometimes you get some hard cores that believe doing anything other than what the mfg says makes you an idiot. I'd imagine these people would be easily lured to Scientology :o
If you read the oil requirement chart in your owners manual, you will see, as Chivota says, many oil viscosities are recommended. I always go with the highest viscosity for the temps I will be in and the fact that even though I'm in a tundra climate for the winter my car is parked in heated garages, so rarely parks for long in 30 degrees or less. I use 10W-40 and will use 15W-40 regularly. That said, I have 84k on my '13 and have no leaks and little timing change rattle on start-up. I have used all the big name oils, based on sales, but it's hard to beat Walmart with a Mobil One coupon.
The trouble with manuals is they become trapped in time whilst oil can progress .
The whole ambient temperature higher viscosity recommendation seems archaic to me and seems based on an air cooled engines .
So how hot does your oil get ?
Certainly not beyond the capability of thinner modern oils with very high thermal breakdown resistance and higher oil film strength of some of the thick gloop recommendations here .
+1 on Walmart, and Costco. The Mobil 5w/30 is perfectly fine here, but I prefer the 0w/40 as the mobil spec sheet shows higher zddp content than the 5/30, which as many know is good for valve train and such.
Either viscosity, these are easy to get, cheap to buy, perfectly suitable for most all our ambient temps, and perhaps most importantly offer all the right additives to keep the engine happy.
Just for reference, I mentioned zddp/phos content as coveted additives because innumerable engine gurus have recommended this over decades (particularly in the aircooled 911 world). But not limited to the old 911s, this additive is beneficial for engine longevity (for exactly what specific purpose escapes me right now, sorry), and it's not a debatable point in the 911 world, fwiw. And of course, too much is bad ...high amounts in excess of 1400ppm has been known to damage cats, but Mobil doesn't go that far so zero worries. The guys who track with cats removed, they use oils with 1400+ ppm as routine.
For anyone who really wants to geek out about this stuff, check the Mobil 1 data sheet: the 5w/30 has something on the order of 800ppm, the 0w/40 "Euro" formula you find at Walmart/Costco has like 1000ppm (if memory serves ...it's been a while since I've read it). I know the aircooled wrenchers recommend north of 1000ppm ...the 15w/50 we use in those engines have around 1200ppm I think. In any event, there's the range that has stuck in my mind. All fwiw, YMMV, do as one will sort of information
HTHS oil film strength , everything else is secondary as numero uno is to prevent metal to metal wear , this is neither high ZDDP , or high viscosity related , two huge misconceptions about engine oil , the #1 misunderstood subject on automotive forums , a bit like car tyre sizes and those pesky tyre & wheel calculators that decieve what actually happens real world....
Engine oil is a balance of ingredients and oil film strength is determined by the oil basestock groups and additive package concentration .

Mobil 1 5w40 Discontinued?
