Certain heavy-duty diesel engine oils can improve fuel economy by reducing frictional and pumping losses.  However, it is critical that the oils also provide the right level of protection to avoid engine wear.

Shell has been at the forefront of development of fuel economy lubricants.  Working in our laboratories and with leading companies and original equipment manufacturers, we have clearly demonstrated the benefits that a high quality fuel economy oil can bring. 

Shell Rimula’s adaptive technology gives outstanding wear protection with reduced viscosity for improved fuel economy.
