    Re: Ulei Motor - ce tip de ulei folositi

     Din cauza ecologiei s-a renuntat la multe substante benefice motoarelor. Reguli stupide. 

    Every fluid is a compromise. Oils recommended by the auto manufacturers seem to compromise protection from wear under severe conditions to gain fuel economy and catalyst durability.

    Re: Ulei Motor - ce tip de ulei folositi

    Asa este . Interesant link-ul tau . Mai ales la pasajul uzura motor .

    Antiwear Property Changes
    Another change that occurred in passenger car motor oils with GF-2 and GF-3 is a more stringent limit on phosphorus, which is part of the zinc phosphate (ZDDP) antiwear additive. The auto manufacturers are concerned that phosphorus will deposit on surfaces of the catalytic converter and shorten its life.

    This is a complicated issue, and the deposits depend on the specific ZDDP chemistry and the finished oil formulation. The industry was unsuccessful in designing an engine test for an oil’s catalytic converter deposit forming tendencies. Therefore, the auto manufacturers set an arbitrary limit for motor oil of 0.1 percent phosphorus.

    Antiwear additives are important in the absence of a hydrodynamic film, such as in the valve train. The antiwear additives are activated by frictional heat, which causes them to react with the hot surface and form a chemical barrier to wear.

    The mechanism by which phosphorus deposits form on catalytic converter surfaces is not fully understood. It does not correlate directly with oil volatility or oil consumption. On the other hand, if engine wear causes oil consumption to increase, the risk of forming phosphorus deposits in the converter would increase dramatically. It seems that preventing wear and oil consumption should be a priority.

    In the past, oil formulators could make a premium product by simply adding more ZDDP. A similar move today would result in an oil formulation that would not support new car warranties.

    P.S. Concluzia : ramane cum am discutat !!!!

    Re: Ulei Motor - ce tip de ulei folositi

     Trebuie sa fac si eu revizia acum. Am folosit ultima oara Mobil 1 0W-40.... si as fi vrut sa schimb acum cu Castrol 0W-30 sa vad cum se misca masina...Unii spun sa nu le schimb asa intre ele ca nu e ok si sa o tin tot pe Mobil 1 0W-40..

    Pana la urma ce este recomandat pentru modelul  2.0 Turbo cod motor z20LEL.

     

     

    Multumesc

    Re: Ulei Motor - ce tip de ulei folositi

     Am facut schimb-ul si am pus Castrol Edge 0W-3, curat ca lacrima :P totul bine si frumos pana acum!

    Poate cineva sa-mi spuna si mie, sau sa-mi dea un link despre ulei in general:

    eu am o intrebare:  ce inseamna indici 0W - 30 

    ce indica primu , ce indica al doilea?

     

    Scuze pentru intrebare!

    Re: Ulei Motor - ce tip de ulei folositi

    Salut, daca ai pana in 100000 de km, eu zic new-life, din cate am vazut in specificatiile pentru turbo diesel, se adreseaza mai mult camioanelor si a masinilor cu incarcaturi.Eu am 0w40 new life si sunt multumit de el, nu a mancat deloc ulei pana acum(si am aproape 10000km de la ultima revizie) si arata si foarte bine uleiul la ultima verificare pe care am facut-o.Acum tu decizi.

    Re: Ulei Motor - ce tip de ulei folositi

    Salutare. tocmai ce mi-am luat filtre si ulei pentru a-mi face revizia. m-am dus chitit pe Castrol Magnatec 5w-30 A1. Mi-au spus baietii de acolo ca ala e pentru ford. OK. Am luat pana la urma Castrol Magnatec diesel 5w-40 dar pe care mi scrie nicaieri ca ar fi si pentru GM. Ati mai pus pana acum din asta? E bun? Trebuie sa iau strict ulei care are norma GM pe el?

    Re: Ulei Motor - ce tip de ulei folositi

    Castrol Magnatec diesel 5w-40 folosesc de 2 ani (ultimele 2 revizii) si n-am avut probleme absolut deloc.

    3.5 litri de ficare data au fost suficienti pt motorul meu
