    really 3126 is made for 15W40

    This engine was used by LIAZ Bus in Russia and we had many problems with oil, secondary oil pim HPOP, frozen oil filter and pressure regulator.

    ECM reads code of low secondary pressure and we had do all this stuff one by one to find the problem..... (((( sometimes it seems to me it is easier to fit injection pump from 3106!!!!!!

    well, you gotta some pain to find this problem
