How to Reduce Vehicle Weight with Lubricants

As automotive manufacturers face increasing government regulatory requirements and consumer demands for more fuel-efficient, lightweight vehicles, they must find more innovative ways to reduce vehicle weight. The main challenge improving fuel economy and reducing CO₂ emissions without sacrificing performance and safety.

The key to achieving this can be found in the use of high-performance lubricants.

Manufacturers can reduce vehicle weight through the use of new, lightweight materials, downsized components and design innovations. These solutions often require high-performance, environmentally-friendly lubricants in order to be fully adopted into the vehicle design. Without the use of proper lubricants, these solutions can require lead to increased rates of maintenance, re-lubrication and repair, resulting in increased costs and decreased customer satisfaction.

Lightweighting Challenges in Vehicles

In order to reduce the vehicle weight effectively, lubricants must be:

  • Capable of withstanding high temperatures and pressures effectively
  • Compatible with new materials (aluminium alloys, carbon fibre, high-strength steel, magnesium alloys, and polymer composites)
  • Inert when in contact with dissimilar substrates
  • Long-lasting, in order to avoid re-lubrication of hard-to-reach components
  • Unable to be diluted or contaminated by exhaust gases or corrosive fumes
  • Unable to discolour or harm nearby components
  • In line with environmental standards

Krytox Lubricants for Lightweighting

High-performance lubricants offered by Krytox can help reduce vehicle weight by offering unique advantages:

  • Non-flammability
  • Long-lasting lubrication; don’t crack or cake with time
  • Full compatibility with plastics, metals, elastomers, coatings, and fabrics
  • High-performance under extreme, harsh conditions
  • High density; creating a thick lubricating film to separate surfaces under load
  • Low evaporation and volatility; leading to no discolouring or harming of nearby substrates
  • Meet environmental and safety standards
  • Odourless

These benefits allow vehicle manufacturers to reduce weight, improve efficiency, meet CO2 reduction targets and reduce the frequency of re-lubrication. Krytox lubricants are used extensively in the automotive industry, including in the process of tyre moulding, EGR valves, NVH and underhood applications.
