And just because the "thicker" oil is 3-5mm2 thicker when warm, does it stay in the storage centres and the thinner one does not? Sorry, that's ridiculous to say that, for example, 13mm2 stays longer in the warehouse and on the surfaces when the engine is switched off than an oil with 7mm2...

The faster a layer thickness there is, the faster it can protect. Therefore, I already wrote that a thinner oil is three to four times thinner in the cold state and thus flows faster, that is physics.

You're right, I should have stated that, sorry my mistake, wanted to set the PQ index or the explanation. Despite your description and explanation, for me, an analysis that consistently shows small elements in several analyses in a row is an indication of a small engine wear. You probably have a...

You misunderstand me. It has nothing to do with speed at the very beginning. When I start the engine and it is completely cold, then the engine runs minimally "dry", depending on how quickly the oil is conveyed at the lubrication points. This moment is the high wear, not what comes after when...

Mercedes' tests only refer internally to their engines and do not allow any conclusions to be drawn that prevents the 229.5 standard LSPI. If an engine has no problems with LSPi, fullsaps will probably not be a problem with this engine.

The starting process alone until the oil has arrived at every point where it should be, the wear is higher than when 200 kilometres of highway. Can also be read in textbooks about the function and operation of an internal combustion engine, among other things.

The PQ Index provides information about this, if I understand what you mean correctly...

„Wenn Sie sich Sorgen über den Motorverschleiß beim Motorstart machen, haben 0W-8, 0W-16, 0W-20, 0W-30 und 0W-40 alle die gleiche dünne Viskosität beim Motorstart“ . That comes from Bill7. This statement is wrong, that's what I meant by my comment. For me, any "faster" cold start is...

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...

What I don't understand yet is how great the influence higher sulphate bag really has. The description says at mobil1 that it is suitable and made for direct injection. The a40 Porsche test also presised internal engine cleanliness even after 160 operating hours. If you have no problems with...

Most particles are smaller than 5 micrometres and are caused by wear and not due to oxidation. This can also be recognised by the values. It is certainly not a complete cure, but an oil analysis says more than they describe it. Even Porsche works with it at the 24h of le mans because they know...

I claim that there is no difference between sae20 and sae40 in approved engines, several analyses have shown this.

They say that a 0W20/0w30/0W40 have the same cold viscosity. Unfortunately, this is wrong. A 0W40 is about three times as thick as a 0W20 at -5/0/5/10C. If I start an engine at 10C with a 0W40 then it is about as if I start the car with a 0W20 at -10C. There are already considerable differences.

For oils SAE40 and higher, for example, phosphorus is not limited in the API. Not everything is identical to the viscosities up to sae 30.

However, your overview is only valid from 0W20 to 10W30. Unfortunately, what applies to the viscosities about it is not listed.

With a fresh oil analysis and a trend analysis series, you can already see how an engine oil performed. You have to pay attention to what an analysis can show you. It cannot show coking or compatibility with seals, for example. Make an analysis immediately after changing the oil from the engine...

Porsche and Mercedes use on gasoline Engines only fullsaps until 2018. No midsaps may be filled in the Porsche gt3 rs up to and including 2017, excluding Porsche A40. Only since 2018 with the gasoline particulate filter came the C40 standard and this midsaps engine oil. The user manual of most...

What do you mean?

I don't think that should be dramatised. There are several absolutely clean engines on the Internet which are and have been operated with Full saps mobil 1. Porsche and Mercedes rely on fullsaps not without reason until the start of the gasoline particle filter. Every advantage also has a...

So I understand correctly that midsaps was really introduced mur because of the exhaust aftertreatment? Cars without particle filters would still be better served with a fullsaps?
