I have been getting 8Km/L on my 1.6 after using a Guard Oil (mineral) which pretty much destroyed my fuel average.
The fuel average is improving each time I take it on the highway. Mostly my route involves local areas, whereas I am dropping my siblings to school + grocery shopping, which again makes the car idle for 1-2 minutes at most + potholed roads of Gulshan-e-Hadeed, requires a lot of breaking.
The oil is great, go for it, you will NOT regret. Value for money and cheap. VERY good oil.
