Congrats on the car , Allah naseeb achay karay
All the questions are answer by Dr Usman perfectly
Filter house is good. But the choice of oil and filter they gave you is strange for me.
10w40 is thicker than required IMO , was it "fully synthetic" oil atleast ? also they should have used malaysian oil filter , its strange why they recommended local guard oil filter
dont ever compromise on engine oil / filter to save a bit of money.
