    In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.13 may 2020

  • What does 0W-40 stand for?

    "0W" stands for the viscosity at low temperatures (W=winter). It is still pumpable down to -40 °C, i.e. liquid enough to spread in the engine at these low temperatures. The number "40" describes the kinematic viscosity of the oil at 100 °C. It contains the range of 12.5 - 16.2 mm²/s.
  • What happens if I use 0w30 instead of 0W20?

    Essentially 0w-30 does not protect your engine nearly as well as 0w-20 but is ideal for more extreme temperatures (temperatures of over 400°F). According to stikkitnow: While the 0w30 motor oil promises to protect your engine from tear, the 0w20 motor oil does this in a more outstanding and dramatic way.
  • Should I use thicker oil in an older engine?

    A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.23 may 2013
  • What oil does a 2016 BMW 328i take?

    A 2016 BMW 328i will require 6.1 quarts of 5w-30 synthetic oil to operate properly.21 nov 2021
  • Is Castrol Oil Good for BMW?

    BMW has been endorsing Castrol since the early 1990's and I have to say that I've never had anything but good results using Castrol. I think it is a great oil and seems to do really well in BMWs. It is reasonably priced, and you pretty much can get it anywhere. If you are using it and like it, stick with it.11 jul 2008
