5W20 API SN/GF-5

API SN designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control systemcompatibility, and protection of engines operating on ethanol-containing fuels up to E85.

The Resource Conserving supplemental category requires further properties. The former supplemental category, which was called Energy Conserving required only fuel saving properties from the oil. Resource Conserving requires further properties like:

• emission system protection
• turbocharger protection
• compatibility with engines operating on ethanol containing fuels, up to E-85

The requirements of API SN with the Resource Conserving supplemental category are identical to the requirements of the ILSAC GF-5 standard.
