Koje si sipao? Gde si pronašao? Jel' u pitanju mineralno ili polu-sintetika?

Based on the results of this study, the following conclusions are drawn:
At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel lubricity.
All diesel fuel sold in South Africa has to meet the SANS 342:2014 lubricity specification to ensure the proper protection of diesel fuel pumps and injector systems.
The low sulphur diesel products sold by Sasol contain lubricity improver additives which are far more effective than 2-stroke oil.
At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number.
No measurable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel.
2-stroke oil can contain around 16ppm zinc, or higher depending on the formulation and batch.
Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits.
Engine test results show that a 200:1 blend of 2-stroke oil in diesel results in a 2% loss of engine power in a 16 hour test due to injector fouling, a risk that would apply to any common rail diesel engine, but could also worsen fouling in older engines.
Vehicles fitted with a diesel particulate filter (DPF) in the exhaust system could experience reduced DPF life due to the collection of ash and metal based contaminants in the filter over time with the continued use of 2-stroke oil.
The abovementioned results should hopefully clear up many of the public misconceptions around the use of 2-stroke oil in diesel and highlight why both oil companies & engine manufacturers do not recommend the addition of any after-market additives, ie. 2-stroke oil, to the fuel tank. It is also good advice to use fuels from reputable outlets backed up by the technical support of a competent fuel company to enable the best engine performance and durability.
Ko zna kako i ko testira sve zivo, hranu, odecu, gorivo, bebi pelene, vazduh, vodu, zemljiste...mi mozemo da verujemo ili ne, da preispitujemo, teorije zavere, svasta nesto. Ovi sto su zagrizeni pobornici 2T ulja isto ne vidim da u vecini slucajeva imaju naucne dokaze (sem ovog linka sto sam stavio, a opet moze se osporiti tacnost), sve je vise bazirano na placebo ili efektu "bolje radi", "tise radi", "lepse radi"...to meni nije nikakav krunski dokaz.BobanR je napisao:Upravo ovaj "zato što ja kažem" princip je najveći problem, i to ne samo kada je ova tema u pitanju. Čitao sam blog kada sam birao motorno ulje. Vidi se da se čovek razume u motorna ulja, ali nigde ne daje odgovor na pitanje "zašto ne?"

Hvala. Jedino tako i možemo da dođemo do nekog zaključka. U protivnom, sve se svodi na puko eksperimentisanje i subjektivne osećaje.Milos je napisao:Dubok naklon za poduhvat i dokumentaciju istog.
1:50 Je možda i previše. Čitao sam da neki prvih par rezervoara sipaju i po ceo litar (1:75). Ima li kakvih promena? Od promene rada u motoru do promene dizni, nešto je moralo da se desi?Ivan je napisao:Pfff pussy 1:200, ja sam probao sa cca 1:100 i 1:50
