Thanks for the reply,
Actually I bought the car 6 months ago, from some one I knew, so I didn't got it checked by a mechanic, one month after purchase I was told by a mechanic that there were xli coils rather than mitsubishi ones in the engine so i changed those. now about a month back, smoke started but only in the morning, major issue is the oil which it burns, otherwise it is giving no problems
It still has good fuel economy, ac is good, everything else is fine, I am just worried about the burning of oil.
