ULTRA 8 SAE 40 is a mono-grade heavy-duty diesel engine oil formulated
from high quality virgin base oil and selected additives. Created for high speed
4-stroke diesel engines, Ultra 8 shields the mechanical components from high
temperatures and wear, extending the engine’s operational life. Due to high
sulfur content in fuel, Ultra 8 offers good alkalinity to battle the sulfur’s acidic
effect.
Recommended for naturally aspirated and turbocharged heavy-duty diesel engines. Suitable for passenger cars, light commercial vehicles, and an extensive range of heavy-duty applications. Designed for highway and off-road applications. Used in all diesel engines where the manufacturer recommends API CF or earlier specification, also suitable for gasoline engines with API SF.
