An oil level indicator assembly for a vehicle engine including an elongated indicator member removably housed in a tubular sleeve which has spaced upper end and lower end portions with an interior passage therebetween and an internal shoulder-like formation therein. The elongated indicator member has a coil spring formation adapted to engage the shoulder-like formation when the indicator and sleeve are in an assembled relationship, thereby establishing a predetermined length of the indicator to project into the engine oil. The effect of oil on indicia formed on the indicator member when withdrawn from the sleeve member shows the level of oil in the engine.
