I have altis 1.6, same engine as of GLI 1.6
oil filter can be removed from under the car, but it is not like old oil filters it looks like it but you do not have to change the mettle part only the internal filter needs to be changed which is of 270 rs of guard, 300 rs of any other Malaysia kind like FA and toyota sells it for 1100 i think.
if you are changing oil every 4 to 5K km then you can even use guard. but if you put grade 4 oil which last 10 to 15K km then use original toyota oil filter.
Any person can remove oil filter by going under the car if the oil changer has that kind of facility, else you cannot remove it from the top.
