I see an opportunity for you to compare the stuff of 6 years ago to the newer stuff of today (ie within the last 3 years according to the attached documents) and report back what has changed.

My observation is oil companies change their branding and advertising hype to sell the product more often than the actual formulations themselves. Recent postings of Castrol, Valvoline are “x” times better than attest to that.

SL & SM formulations aren't all that different and have been with us over that timeframe stated. I recall some SL formulations were so advanced that they call pass the SM tests.

The recommended grades for vehicles in Australia have not changed that much either eg Holden 10w30 from 1999 VT.

Anyway point taken, not to let this debate flare up again, I have said my point of view.

very informative forum!

ive got some Castrol Edge Sport 0w 40 to go in my N54 soon....coming from Mobil 1 0w40 so would be nice to see how it compares or if i will notice any difference!
 
I'd be looking for LL01 approved Castrol Edge 0W40 as used by dealerships here, not the LL04 approved Edge Sport 0W40 a low SAPS oil better suited to diesel engines. Castrol here mark the Edge Sport 0W40 containers as NOT TO BE USED in gasoline engined BMW's. Castrol tech said the oil should have been rebranded and has caused massive confusion in the BMW commiunity. 2001 325CI here.
 
Hhhhmm, interesting debate about Castrol Magnatec here. I used to use Magnatec 10W-40 on my Turbo Nissan Silvia S14 from 1997 (the year that I bought the car brand new) till about 2002. Changed the oil every 5th kilometers (I'm from the Philippines BTW). I stopped using the oil when I changed my valve cover gasket and my mechanic told me that my engine parts were so black with sludge it looked like a diesel engine.

I remember back then Magnatec was marketed as a "fully synthetic" oil. Because of this experience, no Castrol oil is ever going in any of my cars in this lifetime.
 
I'm surprised the Magnatec sludged up your engine with 5000km OCIs. How many km did you do in total when your mechanic changed your valve cover? SR20DETs are not a 'clean running' engine and should run a full synthetic whenever possible. I use Motul 300V in mine. I've used Magnatec in ordinary 4 cyl passenger cars which have remained spotless with 10k OCIs. I don't mind Magnatec - I just wished they sold the 10W30 viscosity here.

I'm not really sure but I've also made the switch to Motul 300V, but I'd also like to try Mobil 1 0W-40.

Where is this information from? (about Edge, I'm aware that VISOM is used in Mobil 1 0w40)
 
Not sure if it is significant but i have only seen 10w40 Castrol Magnatec available on the shelf as a Semi Synthetic.

And it is also the next cheapest to Castrol GTX mineral oil.

As you are in the Phillipines is there any chAnce that it wa a counterfeit product or was the Semi Synthetic product with altered branding.

Just thinking out loud as in my wife's native Ghana it is very common for such things to be done in the pursuit of profit.

Which is why I am in the process of sending some UK purchased oil and filters over to Ghana for a vehicle that my mother in law rents out as a Taxi.

Just waiting on the exact mechnical specs. Only been told it is a Hyundai saloon, lol, I said I would need to know more.

I have used Castrol products a lot and have never suffered any mechanical problems, all were turbo diesels.

All Ford dealers tend to use Castrol products as do a large number of Volvo dealers in the UK, in fact if you buy a new Ford it will come with a Castrol oil flyer in it saying to only use their products.

Even the new Ecoboost engines are specced up for a new to the UK market Castrol product 5w20 full synth. Branded as Magnatec Professional.

I don't see any mention of PAO in that MSDS.

I see "Dec-1-ene, trimers, hydrogenated" at 50-100%, no mention of any polyalphaolefins (PAO) in there

Now I'm no chemist, but to me, that means it is Group III (Hydrocracked).
 
Maybe a mix cuz second CAS number is PAO number...... ....... ...
And in Germany it is not sold as HC. You know about German laws..
 
Can you link to where either of these numbers are PAO:

68037-01-4: Poly(1-decene)
157707-86-3: Dec-1-ene, trimers, hydrogenated

I couldn't find anything other than what I've put beside them above.

But as you say, the German version:

German PDS:

Fully synthetic.

However, the PDS is different:

With no mention of that 50-100% section and the CAS #'s

Also, interestingly enough, the properties are different:

1. Kinematic vis @40C:
UK: 79.3 mm2/s (79.3 cSt)
DE: 80.2 mm2/s (80.2 cSt)

2. Kinematic vis @100C:
UK: 13.5 mm2/s (13.5 cSt)
DE: 13.3 mm2/s (13.3 cSt)

Making me wonder if perhaps they make a different version for Germany? (that wouldn't surprise me.....)
 
68037-01-4: it is a kind from the PAO
family. One kind of PAO. Or am I wrong?
And yes, for Germany EDGE can be
different, with more PAO % than the
EDGE from other countries. The question
however is for the German version - see
the picture please.
Castrol wouldn't have named it
Vollsyntetisch. Some EDGE products as
5W-40 Turbo diesel are written to be HC
on the label for Germany and it is just for
Germany
_________________________
 
It is not theory, PAO is there for sure. Both oils are top products.
Mobil 1 new life should be as good as the old Mobil 1 0w-40, so you may try to ask if there is difference people who have used old and new formula.

German Edge 0w-40 is the oil of Bugatti Veyron, so don't underestimate this oil.

I would personally preffer the Castrol Edge 0W-40, maYbe it keeps the motor cleaner.
Please check these tests. Maybe need help with russian? Oils were exposed to 400 degrees C for 1 hour as far as I remember.

You can see how other oils perform at that test....
