Benefits of Castrol RX
Castrol Oils like Castrol RX Super 15W40 use Castrol's System5 technology to focus on maximizing five key areas of engine oil performance —fuel consumption, oil consumption, oil shange interval, component life, and power. This is combined with Castrol's incredible Durashield booster technology that reduces engine wear, corrosion and the formation of deposits by up to 40%, significantly increasing engine protection in three vital areas.
Castrol RX – Unparalleled Protection
To prove the ability of Castrol RX to protect truck engines over the long haul, Castrol enlisted the help of Scott’s Refrigerated Freightways. Together, they selected a particular truck engine, stripped it down, and inspected. After putting the engine back together, the engine was returned to its ordinary duties, now protected exclusively by Castrol RX. The results showed that Castrol RX offered excellent protection in several key areas, including its ability to control soot and wear.
