Nothing drastic , just the engine didnt feel as smooth as i was expecting, especially when i would rev the engine. it was smoother and responsive when compared with the oil the car came with but not the level i was expecting , i had used Ultra prior in my city 1.3 so i was hoping for that smoothness . but with Hx7 its great . I am getting the same millage i.e between 10.5 and 11.5 .
i guess may be liqui moly is better but havent used it mainly cause i am afraid i might not be able to find genuine one. With shell or havoline etc u can atleast get genuine one from company operated pumps or oil change stations, like shell helix lane one .
