Asalam o Alaikum,
I have already read 4 page long tread @ Pakwheels about recommendation of engine oil for Coure 2007 but i still confused.

I just learn driving and buy a Suzuki Mehran 2005. Kindly guide me for Key points regarding maintenance, especially engine oil (Please keep in mind "the age of engine").

As when i buy it i change with:
Suzuki Mehran - 2005/Mileage/Interval of change/Brand/Your Rating
Suzuki Mehran - 2005/40,000 KM/3000 KM/ZIC HIFLO 20W-50

Thank you in advance
