Silk 3500 SAE 40 API: SF/CD

Silk 3500 is engine oil manufactured from a blend of selected high quality base oils and additives. It is particularly suitable for use in engines of older design and engines operating under less severe conditions. The higher viscosity grades are also suitable for use in certain engines in maritime use. The products may be used in certain diesel and petrol engines where the viscosity and performance level is appropriate.
