Chelation?Where else should the elements come from except from wear and tear?
Chelation?Where else should the elements come from except from wear and tear?
Yup. Its getting to the point you almost need to even order just regular off the shelf products lately. UGHBeen hunting for this oil without any succés Really Hard to find...
Chelation (chemical leaching). I already mentioned this. Esters and AN's, both of which are polar, will liberate material from a surface as they fight to adhere to it (hence my remarks about aggressive chemistry) which in turn shows up in UOA's, which cannot discern between these particles and actual metal. Probably the most common example of this is huge increases in copper from oil coolers showing up as "wear" with oils like Redline, but this applies to other metals as well.Where else should the elements come from except from wear and tear? So if I have a low concentration of elements smaller than 5 micrometres, then this is certainly a good sign. Larger particles are much rarer than is always propagated here. You can make an assessment of the condition of the plant.
This reads like you copied and pasted it from Wikipedia.The PQ index, on the other hand, informs about all existing iron particles that are magnetic, regardless of particle size. Especially for oil samples from gearboxes, diesel engines and hydraulic systems, but also for grease samples, it provides meaningful information about abnormal and usually acute wear processes. The two values are interpreted together, because the PQ index provides information about the size distribution of the iron particles in addition to the pure iron value. Finally, important statements about the condition of the plant can be derived from the combination of both results.
The dimensionless PQ index, the Particle Quantifier index, for oil and grease samples is mentioned in every OELCHECK laboratory report under the rubric “Wear”. This value informs about magnetisable iron abrasion in the sample and is an important supplement to the also declared value for iron content in mg/kg. The iron content is determined with ICP spectrometry, but this only works if the particles are smaller than 5 µm. By contrast, the PQ refers to the total amount of magnetisable iron particles in the sample. Especially for oil samples from gears, diesel engines and hydraulic systems as well as grease samples, it provides useful information on abnormal and mostly acute wear processes. The two values are interpreted together because the PQ index provides information on the size distribution of the iron particles in addition to the pure iron value. Important conclusions concerning the condition of the installation can be drawn from the combination of both results.
Thank you for sharing this!"It's fitting that ExxonMobil, as a long-standing Porsche development partner, also offers special high-performance oils for the Mezger engine family, namely the Mobil 1 FS x1 5W-50 and the Mobil 1 FS x3 10W-60 (from the second half of 2020). . These revised high-performance oils ensure even better wear protection, very good engine cleanliness and low oil consumption thanks to even better sealing. The focus of the lecture from Mobil 1
However, developer Haris Junuzovic had the Mobil 1 ESP x3 0W-40 with the new Porsche C40 oil approval, which is approved for use in all current Porsche V8 and boxer engines. The outstanding properties of this new development range from optimized friction behavior to even greater wear protection compared to the already very good predecessor product Mobil 1 FS 0W-40. Especially in the area of connecting rod bearings, high temperatures and speeds place extreme demands on the engine oil.
len. Lower fuel consumption has also been demonstrated in numerous engines compared to 0W-30 oil. The risk of LSPI pre-ignition occurring in some modern turbo engines, which can lead to major engine damage within a very short period of time, is eliminated by specially tailored additives. The same applies to the protection of petrol and diesel particulate filters. Maximum aging stability, even when using low-quality fuels, enables extended oil change intervals of up to 30,000 km. The result of ExxonMobil's research and development efforts is a high-tech product that combines outstanding technical properties with fuel saving potential. New and performance-enhanced air-cooled 'Wicked Sixes' are supplied with appropriate high-performance oils in a species-appropriate manner. PC Hamburg would like to thank you for this exclusive specialist lecture."
C40 is a low SAPS ver of A40 and C40 will only be a 40 grade just as C30 is only a 30 grade, and C20 is only a 20 grade. There are probably regulatory reasons for the lack of backward compatibility being that Porsche like everyone else is moving to 20 grades and consequently receiving fuel efficiency credits.How much value is C40 to the vast majority of us who don't have a new Porsche. Both M1 and Porsche have said it is not backward compatible for engines requiring A40 or C30. Surely there must be some technical reason and I am for sure not willing to take that risk given that A40 is already plenty strong.
Porsche is not moving to 20wt. Their previous oil standard was A40, which were only 40wt, and that continues with C40.C40 is a low SAPS ver of A40 and C40 will only be a 40 grade just as C30 is only a 30 grade, and C20 is only a 20 grade.

BMW for example is removing heavier 30 grade and 40 grade approval from an engine family which previously recommend them.
C20 is a Porsche approval. They may not use in in their 911 and HP V8's but it exists.Porsche is not moving to 20wt. Their previous oil standard was A40, which were only 40wt, and that continues with C40.
You said it yourself, we're talking about A40 application backward compatibility. Show us an A40 application that's migrated to C20.C20 is a Porsche approval. They may not use in in their 911 and HP V8's but it exists.
If you strictly believe in the approvals then yes, it is not interesting for anyone without a new 911 or 718. Even A40 is probably not very interesting for the majority of BITOG members, let's be honest. Most of the interest is because these oils are also ACEA C3 or A3/B4 and not because there are many Porsche owners here. Since it has API SN+ there's nothing stopping you from putting it in almost any Japanese or American car anyway.How much value is C40 to the vast majority of us who don't have a new Porsche.

Most value in A/C40 is track test sequence. Other than that, it is nothing special.If you strictly believe in the approvals then yes, it is not interesting for anyone without a new 911 or 718.

You mentioned A40 and C30 (see below). Porsche is unlikely to say C40 is acceptable for C30 because C30 is giving away to C20. That was my point.You said it yourself, we're talking about A40 application backward compatibility. Show us an A40 application that's migrated to C20.
C20 is irrelevant in the discussion of C40 backward compatibility.

Thanks.first time i read this old topic.
@OVERKILL beside your scientific knowledge in oils, my compliments for your rich vocabulary and use of words.
A high VI tends to point to high quantities of VII (Viscosity Index Improvers), which are not desirable, as they can lead to deposit formation, and the kind used in most oils are prone to experiencing some shear in service, which means permanent viscosity loss.i wish this oil had bmw approval. why doesnt it? i might cant find still new sp mobil 0-40 but this one i can easily find it near me..price is reachable ,78 euros 5 lt.,10 euros more expensive than normal 5-30 or fs 0-40.
one question though.whenever you guys or some of you ,see viscosity index of 200 you say yikes . is there something i am missing here or isnt it always bad for the consistency quality of engine oils? first time i see it in a mobil oil and i know that mobil is maybe one of the companies that knows why it does what it does.
Yep. The rumor from our MIA friend Argentum was that this oil contains some kind of novel VII that had exceptional shear resistance.Thanks.

The star VII that HPL uses isn't really "novel", just expensive, lol. And yes, insanely shear resistant.Yep. The rumor from our MIA friend Argentum was that this oil contains some kind of novel VII that had exceptional shear resistance.
