Asalam o alaikum. I have a Mira 2013 car bought back in 2015, At that time i Had zero Knowledge about Viscosities and oil grades and different companies, At first i used shell 10W40 Yellow Bottle, then when i started using my car more, my mechanic suggested me to use MOS2 Liqui Moly 10W40 so that i have to change oil less often, My car gives good fuel avg 16-17 KM/L. Now my frequency of use has dropped as i have shifted to different car. (Haven't Changed my oil for 6 months Because very less driven, Currently having MOS2 Liqui Moly 10W 40 in it)
Reading the comments on forums, the recommended oil viscosity is 5W30, Given my engine history and milage 72000 kms, What is recommended oil Viscosity as well as the brand to be used (a Picture would be very helpful).
Thank you in advance
