I had been using Mobil-1 0-40 and then switched to Castrol Euro Edge 0-40 and my motor became much quieter. Then my mechanic put in Liqui-Moly 0-40 and it became even quieter still. Just my experience

I've also noted zero oil loss over the last 7.5K miles with LM vs. some loss with the factory fill over the first 7.5K.

Where?

I've just had the MB dealer service my recently new to me 2013 MB AMG C63 with Castrol Edge 0w/40.

Since the service (circa 2,000 klms ago) it hasn't used a drop, no longer occasionally blows blue smoke on startup and the cam adjusters have only rattled once on startup since the service - unlike all of those traits that were commonplace with the previous MB dealer fill.

I've also used the same Castrol in my Ford G6E Turbo since new 9 years ago, on the recommendation of a couple of tuners and engine builders of these motors and can't fault the oil. Although it is pricey here down under but I usually wait until it comes on sale.

6L of German 5W40 science.

First UOA after ~7K on the first DIY LM fill after the factory fill came out after ~7.5K. Note I am tuned and run a K&N. Seems to be just fine.

Was curious as to the tune (possibly more fuel due to higher boost pressures) and of course the "OH MY GOD K&N WILL RUIN YOUR ENGINE". I like the comment about "excellent air filtration".

Always good to know for sure. Of course if you hang around on most forums if you do more than 5k changes it is only a matter of time before your car explodes.

Truth!

So I am looking at the PDSs for M1 0W40, Castrol 0W40, and LM and only LM carries the BMW Longlife-01....I keep seeing that Castrol carries it but it doesn't that I can see. M1 also doesn't carry it...so only LM has this? Is this a mistake on the PDS?

 

[TiGeo]

No BMW LL-01? Isn't that the big one that folks hang their hat on for this oil vs. M1? Does this mean that LM is a better oil?

 

[kschachn]

Every container of Castrol 0W-40 at every Walmart I've been to here in southeastern Wisconsin has Longlife-01 approval. Others here have reported the same, such as Quattro Pete. Whether it is different in other areas I do not know. My advice is that if you're stuck on that approval you should check what is available in your area. Either that or just go with Longlife-04 approval or realize that Porsche A40 is an equally demanding spec and go with an oil that has that approval.

Or just use Liqui Moly because you like the name and the cool container impresses visitors to your garage. It's up to you.

 

[TiGeo]

I'm not stuck on it, just curious as it's been stated that this is an important spec that differentiates from M1. I'll check at Wallyworld next time I'm there and see what we have in VA - just odd that it's not listed on their spec sheet.

 

[kschachn]

I agree it is odd. Some (at least one) poster showed containers that were clearly missing the approval. Others like myself have never seen one without it.

I also agree that approvals, certifications and licenses are the only accurate method of distinguishing one oil that is "better" than another. However in this case I don't believe you can come to that conclusion by simply counting the raw number on one and comparing it to another. BMW Longlife-01 approval is becoming a dead approval and compared to Longlife-04 the primary technical difference is the ability to compensate for high sulfur gasoline. That is no longer a consideration in most of the world. And beyond that, a value judgement as to the different approvals and certifications shows that Porsche A40 is a highly demanding approval, which Mobil 1, Castol and Liqui Moly all have. Therefore I do not believe that the isolated instance of not having Longlife-01 approval is technically relevant.

 

[TiGeo]

I also note that some of these oils have MB-229.3 AND MB-229.5 and some only have 229.5 - I assume 229.3 is again, an older more-dated approval and its absence probably means f-all.

IIRC, LL-01 is going away, which is why reformulations aren't being re-approved for it. M1 0w-40 was one of the first to lose it with the FS product, SOPUS 0w-40 "Euro" never had it, and now Castrol 0w-40 has lost it. I wouldn't be overly concerned about it as long as all the other current approvals remain.

FWIW, the Amazon listing already shows the new label without BMW approval, alas, like you, I have not seen one of these in the wild yet.

[kschachn]

Isn't that odd? The picture I posted shows the new label with BMW listed, and had Longlife-01 on the back.

Either the picture from Amazon is the latest new label or the one I posted is.

The one from Amazon is the latest, AFAIK.
