oThe "40" represents the oil's viscosity at high operating temperatures: it maintains sufficient film strength even when the engine is hot.
API CH-4, CI-4, and CI-4 PLUS: These are diesel engine oil classifications developed by the American Petroleum Institute (API), outlining performance requirements for diesel engines.
20W40 CF-4 engine oil offers a blend of viscosity characteristics suitable for a range of operating temperatures and provides performance benefits crucial for heavy-duty diesel engines. While it's important to consult your engine's specific requirements, this type of oil delivers reliable lubrication and protection, contributing to the longevity and efficient operation of engines operating in demanding conditions.
DEF AUS-32, also known as AdBlue or AUS 32, is a non-toxic, colorless, and odorless fluid used in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. It's a solution of 32.5% urea and 67.5% deionized water, conforming to ISO 22241 standards.
Purpose: Reduces NOx emissions from diesel vehicles by chemically converting them into harmless nitrogen and water.
Usage:Primarily used in trucks, buses, and other vehicles with SCR systems.
Safety: Non-toxic, non-flammable, and safe to handle.
Standards: Conforms to ISO 22241 standards, ensuring quality and performance.
Storage: Should be stored in a cool, dry place, away from direct sunlight and contamination.
Not a Fuel Additive: DEF is not a fuel additive; it is stored in a separate tank and injected into the exhaust stream.
