Next year Dec would be the end of the COE, this is probably the last time I am servicing this car.
Using Lexuis brand of motor oil for it is not expensive as compare to some other more premium brand.
Change the battery too for the last one has been in service for the last 2 years 9 months, in fact still does its job well, but there sign of bloating observed, so better change than sorry.
Amaron 55B24L HI-LIFE, well recommended brand.
Also change the spark plug to standard Toyota Denso.
