The reason they should measure the oil temperature is that the gas analyser then knows that the oil is at the correct temperature and alters the parameters of the test on certain vehicles. It may or may not affect the overall outcome of the test BUT at least you know it was given a fair chance to pass.
Many texting station do not do this which is wrong as so.e vehicles fail when they ought to pass.
Some testers are ignorant of the fact also.
