This shear-stable petroleum transmission case lubricant is specially designed to withstand the punishment of second and third gear starts, so you can count on exceptional clutch engagement and temperature stability. Recommended for all modern 2-cycle moto-cross gear/clutch cases where SAE 10w30 or SAE 10w40 SE/SF/SG or 80w lubricants are recommended. Eliminates clutch "drag" and "slipping," and exceeds all known manufacturers' warranty requirements and recommendations. Not to be used for an engine lubricant.
