i'll wait to see the many used oil analysis tests that should appear within this thread to then decide.

I was thinking of going with Liqui Molly.

I was wanting to as well but as a previous poster noted above, it does not meet BMW requirements!?...

My mistake. Reread the post on previous page and it states 0w-40 Liqui Moly does not exist as LL-01. Maybe they are misinformed on that as well? Everyone has their own opinion and information outlet I guess.

I have used Mobil 1 0W-40 Euro car formula and the BMW twinpower 5w-30 factory oil. I changed every 5k more or less.

Was thinking of this kit.

Top three easy picks, Shell for BMW, Castrol, and Total. Perhaps Liqui Moly 5W-40 is also exceptional. Every expert (as in petro-chemist, chemical engineers or PhD in the field) you may ask or see on youtube will tell you that the OEM, recommended and approved are mandatory checks. These are found on the material sheet, perhaps the most important, overlooked piece of oil documentation and are a simplified way of saying that the oil's construct/molecules/polymers are actually compatible with a specific engine design.

The N55 is a high performance engine that runs hot. In the US, I regard the 40 a minimum, and higher if tracking. Some manufacturers make an LL-01 5W-40, but, Liqui Moly's full 0W-40 synthetic does not exist as LL-01, but part # 2327 5W-40 is LL-01 certified. Shell's Platinum Euro version (repackaged as Penzoil) makes LL-01 starting with 5W-30/5W-40 but not with the 0W-40. Very specific oil batches exist, for example, for 1980s/1990s oil-cooled race cars that require one oil change per 30-50 lap weekend or 5,000 km intervals other wise.

The specialists say that, under no circumstance one should use oil not meeting the key manufacturer checklist: SAE approval, viscosity and LL-type specifics. The certification process these products go through are very extensive, everything down to the last polymer is analyzed in labs and then actual kinematic testing in test engines. When certified the product sheet will say BMW LL-01 approved. LL-04 is for diesels, different chemicals, not for petrol engines. If a product does not have the BMW approval even though another grade from that same company does, it means that the company has not bothered certifying it OR the manufacturer has not approved it, i.e. it failed testing.

Brand wise, BMW switched from Castrol to Shell (Penzoil in NA). That aside, from Autobahn to race tracks, everyone using French Total swears by it as besting Shell/Castrol and being largely superior to Motul. Total Quartz 9000, made in Montreal, would be the latest LL-01 iteration, with a new 5W-30 just launched February 2018:

Tests with non-approved oils reveal faster oil depletion rate and more engine wear as, in missing metal. One could get by shortening oil intervals to 3-5,000 kms. However, if compatible, certified oils exist, that is the route.

liqui-moly leichtlauf high tech is LL01, I just checked on my jug.

Nice! Looks like the switch is on. Now if the weather would break and STAY nice I could get the 'ol girl out!!!???...lol...

Just for accuracy, note that BMW letter is dated Nov 9, 2013 and the approval is only good for 2 years. An additional 2 year approval must be requested.

I use Castrol Euro 0w40. Bought it from Walmart when it was on sale for $20 otherwise its $25 and Mann filters

Sorry about last image:

[harkes]

WTF..? Ok, so attaching images from the app does NOT work.

[harkes]

OK...this works

i use this oil

[Orion4]

Wonder why while all the rest of sample read below or right at the Universal Averages, Manganese, Titanium, Magnesium and zinc read high? Are they considered sacrificial elements in engine performance?

Here's mine with over 10k miles on BMW oil:

And this is another after I added a magnetic drain plug. As you can see the oil test reflects the plug being added:
