I hav'nt tried that shop. I bought it from Makki Oil Store, Akbar Chowk, Faisal Town Branch. That was fine. In my experience and many of my freinds n Family , using to change Engine oils from Makki Oil Store, and we are satisfied. it have three to four branches in lahore, One is at PIA Society Road, and one is in Cavalary / DHA Road.
In my experience and by some friends knowledge Filter House is Good also, Can be trusted. Their new branch opposite Qazzaffi Stadium is well.
