OTR® 8334ULS is safe for use in heavy-duty, diesel powered equipment for on-road, off-road and marine use. It should be added to the storage tank prior to each delivery to ensure a homogeneous additive/fuel mixture. As with any fuel additive, exercise care by handling it in well ventilated areas while wearing proper eye and skin protection. Refer to the MSDS for more specific information.
