Hello all, please the car's oil gets black very fast (it's lanos automatic 2000)
I put mobil oil, & it gets black after less than 1/2 it's supposed kilos
when I went to my mechanic he told me that the engine is really fine
he told me that i have to put regular cheap oils & change it many times for the engine to be cleaned & after that put the good kind of oil like i used to
Is that right? cause i didnt believe it, & please can anything else cause that
Thanks all in advcancel
