I have nissan Dayz highway star model 2014. Everything is great mashAllah, but i am having problem with its pick. what should i do? Using Jixx engine oil. Not changed the gear oil as yet, purchased the car back in 2016. At the start of the trip and specially going up the slope even if i am going up on any flyover in lahore, it slows down very badly. I really feel the difference when i pushed the accelerator, engine makes noisy sound and acceleration remains same. please help what should i do?
