I bought my Corolla in Jan 2005 and have been maintaining it at Toyota dealership during the warranty period. Then I started using Shell Helix semi-synth oil but kept buying original Toyota filters from Hamza Younus autos in Rawalpindi. For the past two years I am changing my oil (Havoline 10-30) at Caltex pump F-6 super market and it is exact quantity fill 3.5 liters from drums/dispensers.
For all fluids change after 40K kms I go to Toyota dealerships (Capital I-9 or Rawal GT Road), for break service I also go to 3S and buy pads from them.
My car has done 117,000 kms and I have never allowed anyone including 3S to do the tuning. When your car gives you 14kms/lit in city drive with AC and there is no missing or starting problems, there is no need for tuning these EFi cars. I have never done throttle body, injectors etc service also and the car engine response is still like new.
If you go to Saddar, you can check with shops oil you need.
