Learning to navigate lubrication challenges for hybrid vehicles
For hybrid vehicles, compared to conventional engines, many unique challenges exist. These struggles occur because hybrid vehicles have distinct operational features. Adding to it is the fact that hybrids need a blend of combination of an internal combustion engine (ICE) and an electric motor which can exert multiple demands on the lubricants. In this blog, we will examine these challenges while exploring possible solutions to combat it.
Obstacles that hybrid vehicle lubricants face
The continuous start-stop cycle of hybrids is one that can lead to persistent low engine temperature. This in turn causes condensation inside the engine which can amass and result in water buildup, corroding the cylinder walls and piston rings.
Then there is the cooler operating condition of hybrid engines. This can cause the oil to thicken due to increased viscosity and compromise its lubricating properties. The denser oil with its inability to circulate effectively, will be unable to fully lubricate the engine components thus reducing overall engine efficiency.
Hybrid vehicles are no exception to experiencing fuel dilution. Moreover, with the tendency to occur more frequently in hybrids due to their lower average operating temperatures from irregular engine use, it can result in reduced oil viscosity, increased wear, and potential engine damage, if not detected early.
Another challenge is the formation of sludge due to oxidation. Water contamination in hybrid engine oil can escalate the oxidation process, leading to the degradation of the oil which can result in accumulation of sludge, ultimately resulting in below par fuel efficiency, and reduced oil pressure.
Where there is a challenge, Caltex presents a solutionWith hybrid vehicles’ unique challenges that require specialized solutions for engine maintenance, it is imperative to turn to lubricants that can address it. This is where Caltex Havoline® PRO-DS Full Synthetic ECO SAE 0W-20, is a game changer.
It uses the latest fully synthetic base oils and advanced additive technologies including special antioxidants and friction modifiers to provide outstanding protection and performance. It exhibits outstanding protection against heat, pressure, corrosion, and wear while providing excellent oxidation protection and volatility control, and superior cold temperature performance compared to mineral motor oils.
To conclude, while finding the right hybrid vehicle lubricant is key, it is equally important to keep in mind not all hybrids require specialized oil. There are some that use the same range of lubricants as non-hybrid vehicles. Using the wrong oil grade or type can compromise the efficiency and durability of the hybrid system, causing damage to the engine. Additionally, remember to adhere to the recommended oil change intervals and specifications mentioned in your car’s owner’s manual to ensure optimal performance and longevity of the engine.
