lubricant additive solutions for hybrid vehicles:
unlocking the opportunity

hybrid vehicles are a bridge to the future – a natural step in the evolution from internal combustion engines (ICEs) to full battery electric vehicles (BEVs)

Lubrication implications


As regulations governing ICEs become increasingly stringent, a number of automotive OEMs are working on hybrids while developing plans to transition to BEVs over the next 20 to 30 years. Given advancements in lubrication technology toward lower viscosities and synthetics, a common belief is that oils engineered for the latest generation of ICEs are suitable for hybrids as well. Currently, OEMs are recommending standard PCMOs for their hybrid models, and have not introduced specifications for hybrid vehicle engine oils specifically.

Oronite research suggests that hybrid engines can benefit from specialized solutions designed to perform in their operating environment. Demand for hybrid-specific solutions is likely to grow as hybrids evolve and comprise a bigger percentage of vehicles on the road.


the need for differentiated oil

The ICE component of a hybrid electric vehicle shuts down while the battery powers the vehicle, the average engine oil temperature is approximately 25% lower than equivalent ICE. 

Plug-in hybrid vehicles (PHEVs) require the ICE to run infrequently and at a lower temperature than a conventional ICE. When the engine oil does not reach its normal operating temperature, there is an increased chance of water condensation from the engine blowby and higher levels of fuel dilution into the crankcase, creating engine oil emulsion that can impair lubricant performance and raise the risk of rust, corrosion, and increased sludge formation.
