Indicative Equivalents

Equivalents are indicative, matched on SAE grade, base number and ISO viscosity. Always confirm against the engine or equipment maker's approval list before switching. Interflow provides product data sheets and OEM approval letters on request.

Castrol TLX Plus Replacement

TLX Plus 303 and 304 map to Servo Marine 3030 and 3040; TLX Plus 404 maps to Servo Marine 4040, also the closest SERVO grade to TLX Plus 504.

Cyltech Cylinder Oil Users

Cyltech 70 users on HSFO with scrubbers can move to Servo Marine 7050 (BN 70). Cyltech 40 SX and ACT users on low-sulphur fuel map to Servo Marine 4050 ME (BN 40), which carries MAN approval.

Biostat Stern Tube Users

Servo Marine Stern grades are mineral oils. If your vessel needs an EAL under US VGP rules, contact Interflow for the current SERVO bio-based option.
