ZDDP MAXX VS NEO PROTEC GT-EM BRASS FRICTION TEST

[@NeoProtec]

Thank you, very informative. And what kind of pure oil had wear indicators without additives under the same conditions?

[@edogsx]

You're right, it's a lack of me ... You can see the result of only 5w40 engine oil in the WS2 vs h-BN test: kzbin.info/www/bejne/a3bCo4SJaa91bZI

[@TaiLe-dr5ve]

According to you, which protect-oil is the best?

[@godselfmv6]

So NeoProtec provides better wear protection than hBN & WS2?

[@edogsx]

On timken the result is better.

[@alouisschafer7212]

Technically yes but conditions inside engines are not like this test. Dry solid lubricants like WS2 powder is very effective in engines because it forms a lasting protective layer that's even visible to the bare eye on components like camshaft lobes. The bearings in engines are different the two surfaces never really touch they basically float on pressurized oil. The dissolved additives like ZDDP do most of the work in an engine while WS2, h-BN, MoS2 just provide some extra wear protection on top of that base layer established by the additives already in the oil.

@@alouisschafer7212 I agree with what you say even if I am not a fan of solid additives, they have a tendency to accumulate and form agglomerates which can lead to a reduction in tolerances, an increase in friction and in extreme cases at high concentrations, damage to the components. On Timken the pressure in relation to the surface is very high, the best results are obtained with halogen-based additives such as sulfur or chlorine, these react chemically with the metal, increasing its surface hardness without altering the dimensions of the components, there is a problem with the formation of acid halides but with the right chemistry it is possible to avoid this problem.

@@edogsx the best Additive testing method would probably be using test engines and running them with different additives in them for a longer period of time and then disassembling them. This is not something anyone would be willing to do as it would take years and a fleet of vehicles. I don't discredit your testing method. Its amazing to have these tests done regardless and to see that different additives are as effective as they should be. I have bought 25 grams of WS2 powder and want to use that next oil change. Might also buy this NeoProtec GT-EM additive aswell since its not too expensive and people have had very good experiences with it. According to forums its best to add 1-2g of WS2 per Liter of oil. Any more seems to have no additional effect and you want to use as little as possible. I agree with you on the solid additives. You need to be cautious with them. My car is 17 years old, has 242.000 Kilometers on the odometer I don't think that a small dose of WS2 can hurt the engine at all. I want to test what happens when I use WS2 and NeoProtec GT-EM at the same time. Its a crazy idea but I mean there is no risk of any engine damage. To me it is absolutely amazing to see that NeoProtec GT-EM is so effective I mean you are supposed to only use 25ml in your engine and that is enough to condition the oil? What magic chemical is this? Everybody who used it says it immediately reduces engine noise and makes it run smoother so its kind of the same effect as adding Ester to the oil but its even stronger and you only need 25ml thus the engine oil isn't diluted since 25ml on top of 4-5L oil is nothing.

@@alouisschafer7212 Neoprotec is a polymer, one issue I've noticed is that it increases foaming.

[@indravatar]

nice video. very lube turbo looks better result than neo protec.

[@edogsx]

Yes, Very lube turbo has a better result in the Timken test, but the percentage concentration must also be keep in consideration. From the tests I have done with lubricant at very high temperatures I can tell you that the NEOPROTEC GT-EM has a thermal stability superior to any other additive that I have tested. Further on I will publish tests in this regard. Thank you for your support!

Invalid test ... Alot of heat is needed to be applied to ZDDP inorder to do it's job

[@edogsx]

"At very high temperatures, typically above 150 °C, ZDDPs react slowly to form films on solid surfaces even in the absence of rubbing and such films are termed "thermal films". However, when surfaces rub together in a ZDDP-containing lubricant, ZDDP films are generated rapidly and at much lower temperatures, at least as low as 25 °C
