For no 4, really not much outstanding than others? I'm curious to asked because my car is using Mobil 1ep 5w-30, my car very responsive.
Maybe i not sensitive, as long as no weird sound, i ok already QUOTE(Kagekiyo @ Jun 3 2020, 11:04 AM)
In general when it boils down to car lubricants:
- 0W-20: Recommended for better fuel economy
- 5W-30: Geared towards performance as the oil is thinner resulting in better engine smoothness
- 5W-40: Can be used in most car engines (unless stated otherwise in the OEM service booklet) both new and old
- 15W-50: Aimed towards high mileage i.e 200,000km above but feels "heavier" on the engine since this oil viscousity is thicker
Also, to take note is the difference between semi-synthetic & fully synthetic grade lubricants with the latter being able to last anywhere between 8,000 - 15,000km and the former, 5,000km - 7,000km.
To be safe, follow the recommended oil grade and viscousity in your user manual.
high milleage doesn't mean need to go 15w-50. If just to prevent engine oil consumption, time to replace the seals (namely the valve seals and piston rings).- 0W-20: Recommended for better fuel economy
