I think we do not understand each other, here there is a problem that we have a by pass filtration with 2 micron efficiency of 98-99% that does not allow us to see the real damage, everything else is unnecessary, all the justifications of low wear are not valid because the result of the UOA is...

https://amsoil.com.au/blog/what-is-fuel-dilution-in-engine-oil-and-why-is-it-bad/ This brand is also well respected in the forum and worldwide, they claim 3.4% and the user uses their 2 micron bypass filter with absolute efficiency. In general there are many brands like Castrol, Total etc that...

Don't get me wrong, I also use by pass filtration but I am aware that here is an Amsoil with 2 micron and 98-99% efficiency and this partially filters out wear that is not going to show up in the UOA so the low wear rule is not valid to establish non-condemnation of the change. If the unit is...

I did not say that, what I mean is that if we have an increase in oxidation there can be oxidative thickening and the oil thickens, to condemn an oil for oxidation it has to be out of grade, i.e. go over 16cst. All this is to make things clear, we cannot pretend that after 400 hours the oil...

Oxidative thickening, this oil with 270 miles showed 23 oxidation and with 10k miles is 32, basically we can see that the value increases and we can deduce that the oil has thickened and at the same time diluted by this 1l of combat that is inside the engine. The viscosity shown for me is not...

With use the oils can thicken, here we have about 400 hours of operation, we have soot in play and can not rule out thickening. If we doubt the % of fuel we can also doubt the viscosity, at the end we can doubt everything and send double or triple samples in several laboratories and thus have no...

@mattd I just read your post of 15 July 2022 with the 185 hour analysis and I am realizing that there is 20 micron full flow filtration and 2 micron by pass filtration. This changes everything, personally I think with this filtration capability the wear shown in UOA is not representative to get...

I think it is correct that HPL has positive observations, the only thing is that as an amateur I try to reach clear conclusions to protect my investment and I have been very shocked by the 10% condemnation. I have detected cases of TDI engines with broken oil pump belts and totally trashed...

@fantastic Indeed, the wear is reasonable for the moment, we have a 5w40 lubricant that can still be called 5w40 according to the viscosity of the analysis, we have low wear values so carte blanche to continue using the lubricant for a longer period of time. My question was a little more...

As I understand the criteria for maximum reasonable fuel is 4-5% according to many labs. At 8% fuel it is well above what is considered a safe %. Driving with more fuel can cause wear on copper parts and in many tests with the presence of fuel copper and iron are elevated. Actually to see if...

My only intention was to be able to see more clearly the soot and the fuel content since they are two absolutely critical factors for wear in euro 6 TDI engines. It seems that when these levels rise, wear increases. Just edited my previous post that translators sometimes fail, the amount of...

It is curious that from 14k to 18k there is a noticeable increase in wear. Nobody noticed that? I have made a decision to change the analysis laboratory basically because the accuracy of measuring the soot does not convince me, and the fuel measurement is without measuring the biodiesel. I need...

No my nick is Pedro I, it is confused with another one.

I know that concoctions are very frowned upon and the use of mixes between different additives, but here we are dealing with Euro 6 diesel that is continuously regenerated and dilution is a critical factor for engine wear. I have said it on other occasions that when the oil industry releases a...

@fantastic The silicon is due to the use of 25-30ml of Neo Protect additive which raises the levels, it is harmless because if it were dirt entering from a bad air filtering the wear should be seen in piston rings and piston noticeably with these amounts of silicon. Depending on the dosage...

Here is my 18k analysis, it seems to be all under control. Various oils and additives are still being used, Neo Protect raises the silicon AR 9100 raises the potassium, ester raises the oxidation. . Bu pass filtration system from the 60's that uses toilet paper filter, the amount of oil is...

I have a new by pass filter change on both cars. I attach pictures of drop test,even the soot is around 0.1% ,according to my experience with previous analysis could deduce it. I have samples of both cars and I will send samples to analyze the A3, the A4 I am still hesitating whether to send...

MB 229.5 is not the standard for commercial vehicles, it is the standard for cars without particulate filters. This engine is mounted in Vito and Viano where the standard for commercial vehicles MB 228.5 is used, they are generally 5w30 and 10w40 oils with TBN 13-15. You can use MB228.51 as...
