Chain and Bar Oil is a tacky lubricant designed for lubrication of the chain, bar, and sprocket on all types of chainsaws and chain driven machinery. It is formulated with high-quality paraffinic base oils and additives to optimize performance. Anti-wear agents reduce metal-to-metal contact wear between the drive sprocket, the bar guide, and the moving chain. Highly effective tackiness agent to resist throw-off during operation. Tight control of viscosity allows for better calibration of oiling rates, and cleaning agents reduce the amount of pitch build-up on various parts. Chain and Bar Oil is applicable for all brands of chain saws – including today’s high performance and industrial saws, as well as older models. ISO 68(SAE 20) is recommended for winter conditions when temperatures are consistently below 0°C. ISO 100(SAE 30) is used for cool weather conditions of 15-0°C to help assure a proper flow from either hand-operated or automatic chain oilers. ISO 150(SAE 40) and ISO 220(SAE 50) are a good choice for use in mild climates and provide excellent wear protection under hot weather operating conditions.
