  5. CHOOSING THE RIGHT OIL FOR YOUR HYBRID ENGINE

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

Engine oils that deliver against Castrol’s HYSPEC standard

Castrol EDGE Hybrid HYSPEC standard product

Castrol EDGE hybrid

Unlock the edge of hybrid performance

Castrol EDGE Hybrid delivers against HYSPEC, Castrol’s new hybrid performance standard – demonstrating at least 25%1 benefit across the three critical areas of contaminants, engine intermittency and system efficiency. It can also deliver more hybrid power for the same amount of fuel2.

Castrol MAGNATEC Hybrid HYSPEC standard product

Castrol MAGNATEC Hybrid

Non-stop hybrid protection from every start

Castrol MAGNATEC Hybrid features DUALOCK Technology, which ‘clings, locks and protects’ to provide 50% better protection from low temperature3 and restart4 wear. It also demonstrates at least 25%1 benefit against the HYSPEC standard across critical areas.
