5w40 oil

5w40 oil the standard for engine oils before the arrival of 0w-30 and 5w-30 oils

As early as 1997, most car brands filled up with engine oil for the first time with SAE 5w40 viscosity oil.
Many car engines in circulation today (before 2005) require an oil with a viscosity of 5w-40, 10w40 oils having been completely outdated for 15 years.
Certain 5w40 lubricants can be used with particle filters (FAP) and pump injectors on VW engines
Since 2005, 5w40 viscosity oils have been increasingly replaced by more fluid oils: 0w30, 5w30 or 0w40.
