UM je koktel aditiva za stare motore i kao takav nije prporucljiv za iole dobar motor jer ce ga zapusiti.Imao sam Z128 koju sam vozio na original Liqvi Moly ulje u koje sam stavljao MOS4 aditiv i Verlost stop aditiv...
ne slazem se sa ovom delom koji je boldovan. kako mislis da ce ga zapusiti i cime. MOS4
da skapiram ovo kao gresku pri kuckanju jer iskreno za isti nisam cuo. kako moze zbog radi nedosipanja aditiva da okrene lezajeve radilice tj kako moze da ga zapusi. ako ga zapusi zapusice dotok ulja u glavu motora pa ce podizaci ostati suvi a radilica je uvek u ulju tako da ne vidim sta moze lose da joj se desi . u ovom sliucaju ce pre biti da je nesto drugo izazvalo kvar a ne nesipanje aditiva. UM se sipa na 100.000km tj to mu je radni vek, toliko se zadrzava na stublinama cilindara i pravi film. kazu da jedna boca MOS2a ostaje dve zamene ulja. ne znam tacno nisam proveravao. ono sto on moze da uradi je da zapusi filter pa da nema filtracije ulja ali opet zbog toga ne mogu da stradaju leteci. opet nadjem na netu da je prah toliko sitan da prolazi kroz filter...
koristan ili ne (diskutabilno) veci efekat ima na motorima koji zaptivaju nego na onima koji duvaju. jer ako su karike gecrkt nema tog aditiva koji moze da ih vrati u zivot, eventualno mozda da podigne malo pritisak ulja i poveca kompresiju posto smanjuje koeficijent trenja a samim tim snizava temperaturu i to u kombinaciji sa MOS2 (navodno dokazano, covek nema razlog da me laze stim da je kombinacija bila MOS2+METABOND koji radi na skroz drugacijem principu nego UM).
evo sta sami rusi kazu za isti

takodje kolala prica i reklama pa ljudi uzeli i uradili expertizu
Tempting, is not it true fill in the engine magic bottle of liquid and forget about the overhaul forever? Restore worn surface, to return the lost compression, in a word, make the old new engine. The peak of research in this area took place in the 80's, when the urgent problem of reducing friction and wear large scientific research institutes. But until universal victory over the accursed scourge but not gone. But as things now?
<BR> ATTENDANCE AND JUDGES. Of the great number of products that promise to reduce friction and wear, for the tests took four (see photo): two domestic, one American and one Swiss. Our - cheaper foreigners - expensive variation in prices - nearly fourfold.
<BR> For maximum objectivity and accuracy test conducted in the test center GSM 25 GosNII RF Ministry of Defense, inviting leading experts in the Interdepartmental Commission, Russia. The methodology used to conform to two requirements: the situation in the State Standard Commission adopted in 1990, as well as GOST 51176-98. The work was carried out on a special "car of friction" SMT-1, where a pair of friction comprise cast iron block and a steel disc.
<BR> Carrier oil additives has been the Castrol GTX SAE 15W-40 API SF. It is the starting point for comparison, as far as reduced coefficient of friction and reduce wear and tear after the introduction of oil additives tested.
<BR> RESULTS. Antifriction properties of pure oils and oils with additives evaluated imposed on three indicators: the moment of friction, oil temperature in the area of friction, and friction. The lower of these figures, the better. This good result showed only two foreign additives - a relative decrease friction coefficient compared with a net oil from the "American" was about 12%, the "Swiss" - 4%. Reduce the temperature in the area of friction in both - 6 ° C or 3.2%. Domestic preparations for seats in this category chose not to fight.
<BR> Protivoiznosnye weight loss properties are defined iron pad for the same time in a pair of friction. It was the first U.S. air conditioner metal ER, wear down compared with a net oil by 22%. Second place - home "RiMet" - 13% in the third - domestic same "universal modifier" from 8% in the fourth - Swiss remetallizant to 7.5%.
<BR> If you try to summarize the relative reduction of wear and a relative decrease friction can be obtained conditional 'roster. " The highest rating will have an American drug ER - 34%, the second will be "Swiss" Metalyz 6 - 24.5%, third - "RiMet" from St. Petersburg - 13% and complete list of "universal modifier" - 8%.
<BR> CONCLUSIONS. Despite rumors of a disability of some drugs that reduce friction and wear, would like to note that in our experiment all four gave a positive effect. The latter may vary (and in different ways) of the concentration of drugs in motor oil, specific pressure and temperature in a pair of friction, finally, from the regime of friction is simply - the thickness of oil layer. In our case, the effect amounted to an average of 10-15%, but given that in real life motor has to work in different modes, one can hardly expect to increase the resource by more than 10%.
<BR> Get comparable results in changing the viscosity of motor oil at one or two classes, for example, in the transition from SAE 15W50 to SAE 5W30, or vice versa: for more viscous oil will decrease wear, the less viscous - friction loss. So, when using the additives can kill two birds with one stone, but should not expect, for example, the apparent decline in fuel consumption. Loss of friction in the engine are usually no more than 5-7% of the maximum power. Therefore, at full power fuel consumption will decrease by not more than 1-2%, at idle - 5-10%.
