PS: manual says 5-30 or 0-20.. but thats not suitable for our very hot climate in summers.. synthetic grading is bit different as their COV is different from organic oil. ie synthetic are much thinner, organic are thick and viscous..
using synthetic has many advantages.. google them or search here at PW. . thats why cost is a bit high, but compared to 3-4k km for organics, synthetics last 5-6k km, and liquimoly can last upto 8k km.. thus price is justfied.
Donot use SGO.. preferably semi synthetic 5-30 or even better fully synthetic 5-40 is better option..
Kixx, Shell, Zic +/// all are good.. you will feel a noticeable chagne in drive. my experience with 2 cars is just that.. others can tell their own..
