RIDGID thread cutting oils are free of chlorine and other halogens, PCBs and heavy metals.
Dark Oil - Traditional mineral oil with low odor and anti-mist formulation. Nu-Clear® Oil - Clear mineral oil with low odor and anti-mist formulation. Special low temperature properties maintain workable viscosity to -20°F. Extreme Peformance Oil - High performance mineral oil formulated to produce superior quality threads on stainless steel and black pipe. Features Cools threads and pipe during operation. Speeds metal removal. Improves thread quality. Now Chain Saw Oil Chain grooveThe chain has tremendous potential for friction and power loss as it travels around the bar. Energy used overcoming friction is energy that isn't available to remove wood fibers from the log. There are deep grooves in the bar to keep the chain from flying off the bar and to keep the chain cutting straight. There is much metal-to-metal contact. For this reason, there is a constant stream of oil pumped through a hole in the bar to the chain. oilIf the oil is too thin, it flies off the end of the bar by inertia. This leaves the underside of the bar and chain dry of oil. There will always be a little oil coming off the nose of the bar. However, if the oil is too thin, large amounts will splatter from the nose of the bar. To determine this, the operator revs the engine with the bar pointed at a clean surface (like snow), looking for the oil splatter. If the oil is too thick, as it might be in the cold of winter, the bar and chain don't get enough oil. There is great wear and power loss due to friction. In subzero temperatures we often thin bar oil with gasoline or kerosene. The operator should listen if the bar sounds dry. If the oil level hasn't gone down considerably when the gas tank is empty, thin the oil until it flows freely at that temperature. If the oil is the proper consistency, it will pump freely, and will stay with the chain all the way around the bar. Many saws have an adjustment for the oil flow. Longer bars require more oil than shorter ones. The location of the adjustment isn't always obvious, so refer to the owner's manual. While many people use 30w motor oil, professional chainsaw bar oil is more effective because it is sticky. All chainsaw manufacturers discourage the use of old crankcase oil from generators or cars for bar oil. I used to think they just wanted to make money when I bought their expensive bar oil, so I used crankcase oil. What I didn't realize is that there are many small iron filings in crankcase oil that cause excessive wear on the bar and chain. Filings can also plug up the oil filter. Once I understood this, I immediately started using bar oil or 30w oil from large containers. Bars and chains have lasted longer with commercial bar oil. So you can see there are many different Oils for many applications and they have been made for that purpose. Use the right one for your specific need.
