Guys I would like to ask if its ok to use again the ordinary engine oil (usual type of engine oil used on brand new cars) on my 10,000 pms? 6L and 1L (tap-up daw?) were used on my 1,000 PMS and 5,000 PMS respectively. Can I go back to its original engine oil? To those who have done 10,000 PMS with same Innova model (Gas AT) magkano nagastos nyo on fully synthetic and non-synthetic naman? May iba pa bang papalitan aside from engine oil, oil filter, etc? How about automatic oil? Thanks in advance.
