Product Description
Shell Caprinus® XR are premium quality, zinc-free, and chlorine-free railroad and marine engine oils with
an established history of providing outstanding engine cleanliness. Caprinus XR oils are available in SAE 40

locomotives
• stationary engines requiring oils with API CF and API CD (obsolete) level performance
Features/Benefits
• formulated with a unique Shell additive system that is both zinc free and chlorine free
• provide excellent engine cleanliness, especially engine top decks
• provide superior in service retention of Total Base Number (TBN). (Note: EMD and General Electric,
as well as the LMOA, recognize that new oil TBN is not an indicator of an oil’s performance and do not
include TBN in their oil specifications)
• provide extended oil drain interval capability
• multigrade Caprinus XR 20W-40 contains a shear-stable viscosity index improver additive that provides
reduced oil consumption and better fuel economy, allows for longer oil drain intervals through control of
used oil viscosity increase in severe applications & provides better lubrication and oil flow at low
temperatures and during engine warm-up
