Our portfolio for hybrids

Our engine oils for hybrids cater to customers who prioritise performance and protection. The right lubricant can make all the difference in dealing with the impacts of rapid acceleration to high engine speeds, stop-start driving conditions, cooler engine temperatures, oil contamination and system efficiency requirements.

Understanding our engine oils for hybrids

We have two levels of assurance on our products:

  • ‘Delivers against Castrol’s HYSPEC standard’
  • ‘Suitable for hybrids’

Castrol HYSPEC

Only products tested to the HYSPEC standard, and which have demonstrated at least 25%1 benefit across the three critical hybrid areas of contaminants, engine intermittency and system efficiency are considered HYSPEC certified.

As of 1st January 2024, the following Castrol products that have been validated as delivering against HYSPEC:

  • EDGE 0W-20 C5
  • EDGE 5W-30 LL
  • EDGE 5W-30 A3/B4
  • MAGNATEC Hybrid 0W-16
  • MAGNATEC Stop-Start 5W-30 A5
Castrol EDGE 5w-30-a3-b4
Castrol EDGE 5w-30-ll
Castrol MAGNATEC HYBRID 0w-16

Suitable for Hybrids

If you see HYBRID referenced on the front label of any Castrol product, it means the oil performs in hybrids and can be used in a hybrid vehicle where the manufacturer specifies the viscosity and specification shown on pack.
