The Fleetline™ GL5 series oils provide outstanding resistance to lubricant breakdown caused by high temperature oxidation. They also reduce deposits of varnish, sludge and carbon residue on gear teeth and oil seal surfaces. The Fleetline™ GL5 lubricants increase reliability and reduce maintenance costs. They provide excellent lubrication up to 500,000 km as the fluids do not thicken or produce acids while in service.
