Poll: Draining Engine Oil; Warm or Cold?

[midnytwarrior]

I think the best would be if your engine temperature is warm when draining oil. DIY oil change is not an easy task as it requires enough tools and skills. You just need to know the proper procedure to avoid any mistakes. Draining your oil also requires proper disposal to avoid the mess in your area. However, it's still best to bring your car to your trusted car shop if you're still hesitant about the process to avoid any problems that would affect other parts of your vehicle and lessen its functionality. Hope this helps!

Mostly laman ng discussion is yun pag drain lang ng oil. Nakalimutan na pag tanggal ng oil filter. Unlike oil drain plugs na accessible, may mga oil filters na hinde basta basta. Bukod sa naka siksik ang location, minsan mapapaso ka pa sa ibang engine parts like the exhaust manifold, then meron pa yun need ng SST(special service tool) para lang matanggal ng maayos. After maluwagan is next problem saan dadaloy un used oil na lalabas.

The manual states atmospheric temperature not the engine temperatureAttachment 35355

Be careful changing oil while the engine is hot..dripping hot oil could scald you

Atmospheric temperature based on cold starts.
If you look into an oil data sheet, it states specs like "KV*100°C"(engine operating temp), "KV*40°C"(cold)

It's not in conflict with what OJ888 said. The manual specifies operating ranges according to ambient temp, but the second rating is indeed for viscosity at 100°C:
Oil viscosity and oil grades | Lubricants

Viscosity is notated using the common classification “XW-XX”. The number preceding the “W” (winter) rates the oil’s flow (viscosity) at zero degrees Fahrenheit (-17.8 degrees Celsius). The lower the number, the less the oil thickens in cold weather.

Even if you look at SAE tables the second measurement is 100°C/212°F:
SAE Multigrade Oils - Viscosities and Densities
