I have 2007 E60 550i with 85,000 miles.
I did recearch a lot about oils and I know BMW is group III and Castrol same pictures.But question is not that, I want to ask would you use Mobil 0W-30 or 5w30 on this car while a winter time.
Thanks

No. These oils don't meet BMW LL01 spec. M1 0w-40 does. If you like M1, then I would run the 0w-40 grade all year long.
 
VA is not that cold, although 5w30 is approved for your car. Your car calls for: Grade 1......SEO[1]

Synthetic 5W-40 European Oil (EFMQT)
All TEMPS......5w30, 5W-40

[1]To prevent potential engine damage, use only BMW
High Performance Synthetic Oil part No 07 51 0 017 866 or
an equivalent meeting BMW Long-Life rating LL-01.

I would use what it calls for. You didn't specify what Mobil Oil you had in mind? I assume you meant Mobil 1. BTW, 8.5 quarts is a BIG oil pan !

You have to use ONLY BMW LL-01 oils.
Mobil 1 5W30 or 0W30 that you can find in Wal Mart or Auto Zone DOES NOT MEET these requirements.
You can go with Castrol 0W30 (I would use this) or Mobil 1 0W40!
Either way, you will not make mistake with one of these two oils.

No I don't have to use LL01. I'm not planning to use this oil for 15,000, that HTHS number is [censored] by BMW and other motor companies, you have never used your car at such temp while driving to work. Yes I could agree you need more viscosity for race track and it will help at 200 mph in Germany, but in US its all baloneys. I went this reading too much already and arguments. Just read this Ferrari guy (Ferrari forum I guess).

Also as I said before BMW and Castrol is [censored] oil Group III when Mobil 1 Syn is group IV, it's only Mobil 1 and Redline real Group IV, what is this days real syn.

Aha, so you argument is that you know better then BMW technicians and all that designed engine in that car?
Way to go man!
My question is why you asked then here what oil to use if you are so sure in that philosophy?
Also, Castrol 0W30 is PAO Group IV oil!
 
Castrol doesn't claim anymore that Euro Castrol is Group IV.
Why am I asked? I asked because I thought people has knowledge about Mobil 1 oil, to see if 0W-30 is too light for that engine even in winter time, as HTHS 3.0 and Vic 100 C 10.9 compare 5w30 HTHS 3.1 and Vic at 100C 11.0,
Your operational tem is 100C. The 150 C I saw on M3 (used be owned) only when I drove like a mad men switching gears at 5,000- 6,000 rmp.
Also why AMG, Porches, Audi engine are using Mobil 1, did you think for sec it's better oil then Castrol?

1. You're looking at average sump temperatures. Cam lobes, rod bearings, and piston rings get MUCH hotter than that. Those areas are also the toughest on the oil in terms of shear, which is why HTHS viscosity is relevant.

2. I hope you're talking about a pre-2000 M3. For any M3 from 2000 on, shifting at 5,000-6,000 RPM is nowhere near "driving like a madman," and you should be worried that your sump hit 150º C under those circumstances...

Then again, if your idea of driving an M3 hard is shifting at 5,000-6,000 RPM, you probably drive mildly enough that a lighter-than-spec oil wouldn't do much harm in winter. I would never ever try that, but... it's your car.
 
Well then please can you make me think different that I have use only LL01 oil?
I have put to you my augments, about Benz, Porsche and ect, temp share, HTHS numbers, viscosity and type of driving.
I know for fact, E90 328 was making bad sound during start up (it’s well known problem on newer 328 engines), we tried oils: BMW, Castrol 0W-30, and then Mobil 1 and problem gone forever. So I guess Mobil is protecting well on the morning start ups, and as you know, the biggest harm to engine is morning start up.
And one more, I thought same thing, blind believed in BMW oil that is best one as BMW marketing this oil , well until I read a lot and 6 years later I would never use BMW oil on my car, unless it's lease and I'm not planned to keep it. BMW oil is cheapest Castrol ever, which is a blend; it's not 100% synt. oil
 
I'm thinking your visit will be short.

You ask a question, get relevant answers, then choose to ignore them and spew off some more irrelevant facts about factory fill:

Just read BMW/Audi/Benz sites.


For what it's worth, if the Porsche, BMW, MB AMG do indeed factory fill with M1, it isn't 5w30 or 0w30, it's 0w40.

Ummm... not quite. Not that it matters. It's the mfg specs and performance that matters.

They use mobil 1 as factory fill on those vehicles because it meets the spec,and I'm sure mobil pays in 1 way or another to have their name on the fill cap. No different than product placement in the movies.
Why not use what the manufacturer says to use. They built the car,they know what it needs,don't they.

And no mobil product is group 4 bud. The AFE line may contain some group 4,as well as the EP line but NONE are pure group 4.
The only oil that I know of that is pure pao is co-op diesel 0w-40. And we all know pure pao is not good for additive solubility.

Audi uses Castrol

MB, Porsche etc are using Mobil 1 same as BMW is using Castrol, VW is using Castrol etc, it is agreement between those companies.
Now, those oils that are used by MB, Porsche or Nissan GT-R is 0W40 oil which is LL-01 oil, HTHS 3.8.
Do not be naive man, 100c? 150c? Are talking about your coolant temperature? I hope you do understand that coolant temperature does not indicats what is happening inside the engine, on camshafts, valves etc.
Also, 5-6000 rpms? Man I do that everyday on my VW CC.
Also, no Mobil 1 is Group IV, and yes Castrol 0W30 is Group IV bcs it is made in Germany and it is sold overthere as Fully Synthetic oil, which means it has to be made from Group IV or V.
Anyway, putting M1 5W30 in BMW 550i is crime against that car manufacturer:)

No. But you can change your mind if you want.

Making less noise is not the same thing as protecting better.

I agree, the correct grade would be 0w40. Which does have a significant dose of PAO in it. The previous version, the SM version we still get in Canada is a PAO-based oil.

The AFE oils also have significant PAO content.
 
If you are dead set against a straight 0W-40, then why not do a 70%/30% mix (or even an 80%/20% mix) of M1 0W-40, and M1 AFE 0W-20, especially for the winter OCI??

You get all of the benefits of BOTH oils (decent V.I., fairly high content add packs, and a decent dose of PAOs) along with a slightly thinner HTHSV than the straight 0W-40's 3.8 number.

As others have indicated, use a 0w-30 (German Castrol), 5w30 (BMW's oil), 0w40 (Mobil 1 Euro), or 5w40 (Pennzoil Ultimate Euro) oil that is BMW LL01 approved. The 0w (indicating more pour point depressant additive) oils will give a little better cold starting. I lived in NoVA for 35 yrs and owned/drove about 15 BMW's during that time, including several M cars with factory specified Castrol 10w60 in the sump, and never had a problem starting/driving in the winter with BMW spec'd oil even when the temp was sometimes in the teens.

Your contempt for factory approved and specified oils is misplaced. Oem's and their lubricant partners do a lot of research, development and testing, in the lab and in the field, arriving at their engine oil approval specs. There was an excellent article to this effect in the journal of the Society of Tribilogists and Lubrication Engineers in May 2012. I can't provide a link because its been archived, but a similar source is available in a slideshow presentation by Lubrizol (Google "pdf Lubrizol Value of Performance"). Finally, this short article describes the tests involved in getting an engine oil approved by BMW: http://www.top1oil.com/USA/newsletter/2011/July.pdf. Here is more info on one of the testing labs BMW uses in its lube r&d and approval: http://www.isp-testing.com/en/.

BMW's 5w30 oil is a quality, top tier oil, and most BMW dealers sell it at a pretty reasonable price .
