Hi pakwheels users
My question is that i have lancer 89 model with engine 4g13 it was running on cng when engine was swaps but i shifted it on petrol, as cng was not available. My question is that first 2 plug have oil in it. I have tuned the carb and i am getting 10 to 12 kmpl in city with soft foot. What is causing the oil in the plugs is it valve or piston rings plus what will be the cost coz i am a student and i really like my car.
