Choosing the right oil for your hybrid car

The right lubricant can make all of the difference in dealing with the unique challenges of hybrids. We have a range of oils suitable for hybrid technologies.

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:

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

If you see hybrid in the fuel type section on a 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.

If you see the HYSPEC logo on a product…

It means our oils demonstrate at least 25%1 benefit across the three critical hybrid areas of contaminants, engine intermittency and system efficiency.
