Synthetic blend, or Semi-Synthetic Engine Oils, are blended from premium synthetic base stocks and highly refined petroleum-based oils.

Synthetic base stocks are crafted in a laboratory to deliver the highest-quality and most efficient performance characteristics to high-performance engine oils - blended with petroleum base stocks, these compounds harbor the many benefits of both synthetic oils and mineral-based oils.

Combining these two types of lubricant bases makes for an affordable, yet high-performance lubricant that is formulated to extend oil and engine life, protect internal components, and reduce the formation of rust and deposits.

These oils have a unique additive technology to prevent oil breakdown and the corrosion of engine components. Their semi-synthetic bases provide exceptional thermal stability which allows for extended intervals between oil changes.
