oh well I used toyotas oil in my rolla 12 model 1.3 and it used to give me not more than 9.5milage .. i changed it to zic OW 0w30 and believe me the milage in return was outstanding..it was always above 13.5kml and I used the car in Abbottabad city ..when I changed to Zic xq 5w40 on the next oil change the milage dropped to 11kml and it didnt give better than this in local .. so the oil matters alot..
i used my corolla in peshawar and it served me pretty well without any problems with zic ow 0w30 .. ill recommend this oil for your wagon R Jamal .. try it once you will feel the difference .. i can give yu an authentic distributor address shop location which was given to me by Zic manager who used to come and I always poured oil from him. Anyways try your luck .. temperature does matter but these oils have been tried in hottest weathers .. try it yu won't regret your decision ..milage and thr K series engine with this oil will be smooth for the years to come .. dont use PS crappy oils.These jahils have no idea.. K series engines are new it requires better oil instead of these thick muddy oils poured by them which they also pour in mehran [emoji16]
lastly it doesn't mean the expensive will return something exceptional in return .. ZQ 5w40 was expensive but it didn't impress me in the milage ..the changing interval was 8 to 9k but who we dont risk this much milage because of dusty environment plus the filters ..
