ABSTRACT:
A device for conveniently sampling and testing oil from the crankcase of an internal combustion engine comprises a tubular member, installed in the dipstick guide tube of the internal combustion engine and having a chamber above the guide tube inlet, and a vacuum filled sample receptacle having a seal which, when the receptacle is inserted in the chamber, is opened causing oil from the crankcase to be drawn into the receptacle. When the receptacle is withdrawn from the chamber the seal automatically closes, providing a convenient container for the oil sample to be sent to a laboratory for analysis. Optionally, to test the oil for acidity at the time the sample is received in the receptacle, the receptacle may contain a reagent which will indicate by color the pH of the oil sample.
