Specifications and Approvals
- Alexia LS is approved by Wartsila (Sulzer).
- An approval trial with MAN B&W is in progress.
Applications
Shell Alexia LS is a special 40BN, SAE 50 cylinder lubricant, for improved piston running conditions in low speed crosshead diesel engines burning low sulphur fuels.
For use in:
- Cylinders of low-speed crosshead diesel engines burning fuels with sulphur content below 2%wt, where the designer recommends a lower Base Number (BN) oil to reduce the risk of “sudden severe wear” or scuffing.
