ahmedfaraz79,
for your Suzuki Mehran 2008 model, we would recommend you go with our Valvoline XLD 20W-50 SG grade in 3L pack.
Even though this is an SG grade, it is made from Group 2 base oils, so it will be gentle for your engine, as well as give you greater drain interval and smoother running.
We will attach a picture in our next post.
Thanks.
