With the advancement of modern, electric vehicles, the way in which oil and lubricants are being used within the automotive industry has shifted dramatically. Not only do electric vehicles use these types of fluids in a different way, advancements in oil development mean that fossil fuel-powered cars have also benefitted.
Petrol and diesel engines
Traditional petrol and diesel cars rely on oil to ensure proper movement of parts and components in the combustion engine. This also means that oil changes should take place at certain intervals, usually after the vehicle has reached a set number of miles.
However, modern lubricants have been developed that now allow vehicles to cover more mileage before a full oil change is recommended. In some cases, this might even be up to between 10,000 and 15,000 miles if fully-synthetic oil is used. This type of oil is more expensive but offers greater protection and performance.
Electric vehicles
With sales of electric vehicles in the UK hitting an all-time high at the beginning of 2023, more drivers than ever are experiencing the difference in maintenance compared to that of diesel and petrol engines.
Driveline fluids
Synthetic-based oils are commonly used in such vehicles as they allow a good balance of thermal protection, lubrication and electrical performance. Driveline fluids are a type of lubricant that offer these properties, plus they can also improve energy efficiency.
Thermal management fluids
As these types of motors are liable to become extremely hot, an important aspect of developing new oils for EVs is their thermal capacity. Advanced fluids are being developed that have outstanding heat transfer and cooling capabilities.
An integral part of their function is to assist with battery temperature management, as poor thermal stability can affect the life of the battery. Advanced fluids are designed to reduce corrosion and general wear on the cells and therefore help extend battery life.
EVs also require a range of oils and lubricants in the components that make up the chassis, wheels and brakes.
Ultra-high-performance grease
Greases are often used for a variety of other components in electric vehicles. Superior products that are designed to reduce friction, as well as protect against wear and tear, are the preferred choice.
Grease is also designed to provide protection against corrosion and oxidation, helping to extend the life and performance of components and increase safety.
The future of oil developments
As further advances in technology are made relating to electric vehicles, new oil and fluid innovations are also highly likely. With new petrol and diesel car sales due to end in both the UK and the EU by 2035, the performance and safety of electric vehicles is set to be high priority. And that means ensuring that each individual component is able to function at its optimum.
