Thermal stability
Helps resist thickening in stop-start and high-load running compared with a conventional mineral oil.
Engine Oils
Semi-Synthetic Engine Oils
Balanced everyday protection for gasoline and diesel engines, including turbocharged applications, with reliable thermal stability and wear control.
Product family
A practical blend of synthetic performance and everyday service.
Semi-synthetic oils sit between mineral and full-synthetic families: enough synthetic content for cleaner high-temperature running, with a cost profile suited to mixed fleets and older engines still in daily use.
Use this family where drivers want stronger oxidation control than a mineral oil, without moving the whole park onto a full-synthetic grade. Placeholder specs below can be replaced with approved product data.
