Salam my fellow Pakwheelers. I have a 2013 altis 1.6 which is driven 70,000 km first hand by me. Maintained by toyota and currently on 20w50 toyota petron.
Kindly suggest if i should keep putting 20w50 or change to a 10w or 5w as i will not be getting further oil change from toyota and if 20w , then kindly recommend a brand other than toyota petron.
Thanks
