    ### ICHIRO Mineral Diesel Engine Oil - SAE 15W40 - 4L

Plan your marine servicing around ICHIRO Suzaku SAE 15W40 oil in the 4L container size. This listing identifies the particular grade and carton configuration, so the lubrication requirement and purchasing quantity can be checked together before ordering.

Suzaku uses hydro-treated base oil and an additive package intended for demanding diesel-engine service. The formulation addresses the lubricant demands of engines using exhaust gas recirculation, where the engine’s specified oil performance remains a key selection detail.

The stated viscosity is SAE 15W40. Confirm that grade and the exact performance category required by the engine before ordering; a heavy-duty diesel description does not establish compatibility with every diesel installation.

Use the engine service instructions to determine the oil quantity, filter requirements and change interval. Check the current oil label or technical data against any required API or ACEA category rather than relying on a general reference to those standards.

This code is supplied as 6 containers of 4L, giving 24 litres per carton. The larger containers are useful when arranging the oil quantity for servicing or maintaining a workshop supply. Check the carton quantity as well as the container size when calculating the amount required.

The ICHIRO range is produced in Singapore and blended and packaged under licence from ICHIRO Corporation by a member of the REPSOL group. The blend uses fresh oils rather than used oils. These manufacturing details identify the range; the particular grade and performance requirements remain the deciding factors for your engine or gear assembly.

### Choosing and using this product

For fuel treatments or additives, follow the product label for the required dose and conditions of use. For oils and greases, use the equipment guidance to identify the correct service points and specification. Avoid mixing guidance from different formulations.
