I want to share my personal experience regarding the mobile oil, i live in Peshawar, here roads are so jammed because of work on BRT my car was giving me around 13 in local which was absoloutely fine because of roads condition, i have Passo 14 just done 30k on odo.
Last week i changed my mobile oil to zic 5w 20 fuel economic, i felt a massive change in car perfomance and the car is giving me average of around 15+ and on gt road crossed 22kmpl.
I was really surprised so i'll suggest you all ZIC 5w20 for your rides.
