Dark engine oil

[jmpet626]

The oil getting dark on a diesel is normal, heck after driving it home from a fresh oil change in the casa it could already be black. What I'd like to know is how long the oil should stay in the engine (actual kms driven vs actual running time). Does anyone know if Caterpillar still does EOA's?

+1 Pag uwi ko galing PMS ng montero pag check ko dark na ulit yung oil parang hindi bagong change oil
