recently i had a bad experience with local oil change shops in my area which is Wapda Town/PIA society.
the name of shop is Jan-e- Janna and situated on the main PIA road.
due to ramadan timing, the oil dealer i regularly visit was closed and i had to travel on motorway so i had no option but to find any other option.
in vicinty i found this shop open, late in night so i decided to give it a try, the owner seemed nice and trust worthy guy, so as usual Kixx G 20W-50 was poured in my car, 10% discount was given and on the top a free car wash.
i left happily but the car didnt behave the way it used to do, normally i feel the engine more quieter and smoother after oil change, but as i didnt change the air filter so i blamed that and carried on with routine considering the Toyota engines are bullet proof, lolz
after 1k reading, in morning i cud hear the oil pump rattle, working overtime to pump the oil, this noise was new to me but i thought it might because of age of engine blah blah ...
NOW, this time i got the oil changed from regular place used same oil, the engine immediately became smoother and after driving almost 850 KM, there is no oil pump rattle in morning.
so it made me believe with sufficient evidence that the previous oil change was not legit.
