I am not sure if the price difference between the fully synthetic oil versus the semi-synthetic is practical now because of the high costs of fuels. I am more inclined to do a more frequent oil change thus I am leaning towards using semi-synthetic which is what is in my fortuner right now.
My other gas vehicle is using synthetic ever since but since this is a sedan, I only need 4 liters per oil change. The Fortuner needs 6 liters so the price difference is substantial. I also noticed in my other car though that when I do my 10K kilometer oil change, the oil is already very dirty by this time so it might be helpful for the car engine to change the oil more frequently.
But then since the fortuner is still new, the oil won't be as dirty after using it for 10K kilometers.
I need your enlightenment on this.
Thanks in advance.
