This is the replacement silicone damper oil that is included in many of the Traxxas kits. It is approximately 30 weight oil (Traxxas does not list exact weight), comes in a 1/2 oz (approximately) bottle and is clear.
Silicone damper (shock) oil is better than petroleum shock oil because
silicone oil is not affected by temperature.
One approximately 1/2 ounce bottle.
