Lubegard Power Shield Bar and Chain Lubricant features the best performing lube, even under the most extreme operating conditions. The Lubegard power shield bar and chain oil is by far, the best performing lube available anywhere. This is mainly due to LXE technologys unsurpassed heat sink and heat transferring properties. Any bar and chain application will run cooler and longer with this lubricant. Less heat equals less wear. Less wear equals longer life. LXE technology actually possesses polarity to metals. This polarity occurs due to the charge distribution of the electrons in the carbonyl group of the LXE molecule and gives the molecule longer residence on the metal. Simply put; it is attracted to metals and improves heat transfer, which reduces wear. This is especially important to maintain constant hydrodynamic lubrication and in applications near-boundary lubrication, making it by far, the best lubricant during start-up conditions. It is 100 percent biodegradable. Sacrificial oils leave a tremendous amount of waste behind. Since this is not a petroleum based lubricant, you can maintain trees and brush on your property, without being worried about leaving bio-hazardous waste behind.
