The color thing isn't trivial. Non colored oils or those that are red make it hard to tell if there is oil in the gas. I am paranoid about running a saw with no oil in the gas!I dropped and bucked about 25 locust trees in Maryland Friday and Saturday. The Yamalube really is impressive oil. It is a much thinner viscosity oil, and mixes very well. It had no scent that I could smell, and the saws seemed to burn really clean on it. Oh......I like the color too.
