International Lubricants Inc. announced the launch of its new LUBEGARD® Heavy Duty line. The line is ideal for servicing heavy-duty equipment — particularly if it is past warranty. Heavy Duty Engine Protectant, Gear Protectant and Power Transfer Protectant are three of the four new products. The fourth new product is Heavy Duty 2-in-1 Coolant Treatment. LUBEGARD® Heavy Duty products are a smart way to keep your equipment running longer and with minimal down time.
