New Total Engine Lubes

Total Canada has launched the new Rubia Optima range designed for heavy-duty diesel engines and complying with the new API CK-4 and API FA-4 categories to meet greenhouse-gas emission limits. The existing CJ-4 category, developed nearly a decade ago, will be replaced.

CK-4 oils will be backwards compatible.

The new lubes are said to provide better engine protection and what the company calls “an unparalleled level of performance”. They’ll help limit carbon dioxide emissions while improving the engine’s fuel consumption and allowing the longest oil drain intervals authorized by manufacturers thanks to improved oxidation resistance, says Total.

The new oils actually surpass the new CK-4 and FA-4 specifications.
