I have noted that engine oil gets black soon (even after 800 km) after i used to drive FX on patrol but it was ok on CNG. i am using mobil super since a long time.
when i inquired the situation from oil change mechanic He said oil is OK but it is dirty as my car's carburator is using more fuel than is used for eginition.
My average in Lahore City traffic is 12km/L. i think this is much low as compared to 800cc car.
i inquired the situation from another mechanic he is telling carburator needs service.
2 months before when i shifted to patrol i got it serviced along with tuning from my regular mechanic and he is of the view that this average is ok. my mechanic is good for CNG cars and i think not much for Patrol.
suggest me what is the problem and how it would be solved and where i should i go.
